Amyloodinium ocellatum – a.k.a Oodinium a.k.a. Marine Velvet Disease

»Posted by on Jan 11, 2019 in Blog, Cedes Militante, Conservation, Education, Heather, News, Saltwater Fish | Comments Off on Amyloodinium ocellatum – a.k.a Oodinium a.k.a. Marine Velvet Disease

Amyloodinium ocellatum – a.k.a Oodinium a.k.a. Marine Velvet Disease If someone were to ask me what the most deadly marine disease was, one of the first things that come to mind would be Marine Velvet. Unfortunately it is not uncommon, and the dinoflagellate infestation can frequently be found in newly imported fish. The A. ocellatum parasite responsible for premature fish loss is actually an algal protozoan and closely related to the dinoflagellates that cause red tides. ocellatum can completely wipe out an entire aquarium in the right conditions: poor nutrition, low water quality, improper life support equipment, and other stressors.     Life cycle of “Oodinium”: Life cycle is typically 6-12 (but as long as 28) days depending on temperature. Trophont stage- the only time you can see the parasite, nonmotile and hosting a fish absorbing nutrients for reproduction Encysted stage- a.k.a tomont or palmella, the parasite divides while still on the fish. Incubation period can be 3-6 days. Dinospore stage- newly hatched parasites emerge from cysts and are free swimming, looking for new hosts   Symptoms Marine Velvet is not easy to spot. TIP: make sure to look at thin, transparent areas of your fish and try to view these areas at an angle to best see affected areas. First signs of infection include rapid respiration (the gills are typically attacked first). A classic infestation has been described as a dusting of powdered sugar or a foggy or faded area on the fish’s body and can be accompanied by cloudy eyes and fins. Fins may appear clamped and fish may stop eating. You may see the fish flashing or scraping its body against décor or the substrate. Severe infestations look velvety in texture, thus the name. In these instances you will also see sloughing off of the protective slime coat. Death can occur in as little as 12 hours, without any outward appearance if the gills are severely damaged by the parasite. It has even been known to colonize the guts or esophagi of many fishes, making it difficult to spot and control.   Treatments Prevention! Especially in reef tanks, as most medications can kill coral and live rock! Have the right equipment to house your fish, proper UV sterilizer, feed a nutritious diet, quarantine new fish, be educated and ask questions when selecting fish for your tank, etc. This disease can happen so fast, that sometimes aquarists loose their whole tank in a day or two and never saw anything wrong. Repeated fresh water baths dosed with quick cure or formalin may dislodge some of the trophants on the fish (about 10-15 minutes). Fish must be caught quickly or stress of netting can cause disease to worsen. Treatment with copper sulfate (i.e. Cupramine) for 21-30 days. Chloroquine phosphate treatment could be used. Reef safe medications, though much weaker include Rally or Hypercure. Antiparasitic foods and garlic additives may also help if the fish is eating. Monitored hyposalinity may enhance effectiveness of treatments (1.010-1.013). Increasing temperature will increase reproduction rate of parasite and shorten life cycle for decreased treatment time, however, the fish’s metabolic rate and demand for oxygen also increases. If you think you might be noticing signs of Oodinium in your home aquarium, stop in to see one of our marine certified aquarists to diagnose and discuss your situation. We are experienced with this pathogen and would be happy to help you prevent and eradicate it!   Cool side note: A quick and immediate drop in salinity has dramatically increased effectiveness in controlling “Oodinium”. The parasite has semipermeable membranes and cannot control osmosis. They begin to absorb water as the cells try to equalize osmotic pressure with the change. Eventually, most strains of Amyloodinium pop like fish bags filled with too much air (in this case...

Freshwater Nano Fish

»Posted by on Nov 16, 2018 in Blog, Conservation, Education, Freshwater Fish, Mike D, News | Comments Off on Freshwater Nano Fish

Freshwater Nano Fish               Nano aquariums have been popular for quite some time.  They can light up a desk or kitchen counter top and can easily be the center of attention in any room.  These small aquariums, generally 10 gallons or less, can be a great alternative for those that feel a large aquarium is too much work or too daunting.  Nano tanks do come with some challenges.  The main challenge is that with less water volume there will be a more rapid shift in water quality.  It is important to be consistent with regular weekly water changes for the long term success of the aquarium.  The best looking nano tanks in my opinion are ones that are fully planted.  With the use of driftwood, various stones, and lush green plants you can turn a glass box of water into an underwater oasis.  I’ve seen some professionally designed nano tanks that will make you think you’re looking at a miniaturized mountain range.  The limit is your imagination.              Now onto the main attraction, the fish!  Here at Absolutely Fish we carry a wide selection of nano fish to choose from.  One of our most popular species is the celestial pearl danio.  This fish is relatively new to the hobby, only being discovered in 2006 out of Myanmar.  This micro-danio will reach an adult size of about 3/4 of an inch.  They possess bright red fins and a brown body covered in gold spots.  They are quite active and can be kept with many other tetras, rasboras, and peaceful barbs.             Another extremely popular fish we regularly stock is the Amanda tetra, also known as the ember tetra.  These miniature tetras come from the Amazon and are great schooling fish.  They are a solid orangey-red color and are surprisingly hardy for their size.             One of my favorite fish selections for nano tanks are dwarf corys.  The two species we most commonly see are Corydoras habrosus and Corydoras pygmaes.  These cory catfish are a schooling fish so a group of five or more is recommended.  They prefer a sandy or smooth substrate and a diet consisting of small sinking pellets and bloodworms.             Another colorful option for a nano aquarium would be Endlers Livebearers.  Endlers are a form of guppy native to Venezuela.  Males reach a maximum size of 1 inch and females closer to 2 inch.  The males possess all the color and come in many different color varieties.  Some of the colors we regularly bring in are the flaming pink, electric blue, and yellow cobras.  Be careful mixing males and females because they are prolific breeders. Other than fish we do bring in some interesting invertebrates to add another dynamic to your nano aquarium.  Thai micro crabs are quickly becoming a crowd favorite.  Their care is similar to that of fancy shrimp.  They require very clean water and lots of plants to hide.  They should be kept with only other small peaceful fish.  These crabs are omnivorous and will spend most of their day foraging for microorganisms.             Recently we have seen the popularity in nerite snails surge.  We now regularly carry a few varieties of these excellent algae eating snails.  We regularly stock the zebra nerites and tiger nerites.  On occasion we will bring in fancy horned nerites and red racer nerite snails.             Here at Absolutely Fish we do our very best to bring in only quality fish from expert supply chains.  This is as important to us as well as you.  We encourage you to come to our shop and discover what you love and learn from...

Top 5 Frags to Buy at Absolutely Fish

»Posted by on Nov 2, 2018 in Blog, Cedes Militante, EricR, News, Reef Aquariums | Comments Off on Top 5 Frags to Buy at Absolutely Fish

Top 5 Frags to Buy at Absolutely Fish By: Eric Russo   5. Zoanthids/Palythoas Zoanthids and Paythoa buttons offer any hobbyist the opportunity to add a variety of color into their tank. They are relatively easy to maintain and will grow at a decent rate. Zoanthids in particular are very prone to pests such as nudibranchs so dipping new purchases in a coral cleaning bath is highly recommended. It is important to use caution when handling and particularly when fragging zoanthids and palythoa buttons due to the dangerous palytoxins they possess. 4. Montipora capricornis This montipora species is most notable for the unique way it grows in a stacked plating formation. As far as SPS corals are concerned, this is a great option for beginners, it is fairly easy to keep and will grow quickly. To enjoy the potentially explosive growth it can be known for calcium and alkalinity levels should be monitored and kept in optimal ranges. As with zoanthids and palythoas these corals are prone to pests and should be dipped before adding to the tank. 3. Acans (Micromussa lordhowensis) Knows colloquially as “Acans”, these LPS brain corals have been reclassified within the last few years from the genus Acanthastrea to the genus Micromussa.  Taxonomy aside, these corals make awesome frags that are easy to keep. Individual polyps can be found with multitudes of color, with many earning a nickname like “rainbow”. These corals benefit from semi-regular feeding and can consume food as large as a pellet or a mysis shrimp. 2. Frogspawn  The genus Euphyllia has several corals that could be in a top 5 list, but there’s something about frogspawn that gives it the edge. It features the same long polyp extension seen with torch corals but with a more interesting polyp shape like a hammer. It’s the best of all Euphyllia has to offer, and frags here at the shop are always among the first to sell. While slower growing than the other corals on this list it is still easy to keep alive and thriving. Keep in mind when placing it in your aquarium that is has a longer reach than most corals, it is semi-aggressive, and it can sting neighboring species. 1. Green Star Polyp We’ve made it to the top slot on the list and some may find this pick controversial. Green Star Polyp is an excellent choice for beginners to experts alike; it has vibrant coloration, pleasing motion in the aquarium, and it grows quickly….very quickly. This coral is probably only rivaled by Xenia in terms of potential growth rate and can be overwhelming for those who are unprepared. Careful consideration should be taken when determining placement because under ideal growing conditions, it can take up more “real estate” in the aquarium then you intended. Many hobbyists have had experiences that left those feeling like Green Star Polyp were akin to other reef pests like aiptasia, but when properly placed and tended to it makes a great addition to any reef. There are so many other corals that make great frags, but these are some of my personal favorites. Feel free to share your favorite frags or just talk coral in general with us in the shop! Stop by soon to see these and many more awesome options for your reef tank!...

Live foods to buy, New Jersey

Live foods to  buy, New Jersey

What should you feed your picky aquatic eaters?   by: Heather H. Live foods must be chosen with care. In good condition, live foods can add to aquariums fishes’ diet as they contain fresh, active ingredients that can aid in digestion. Additionally, they tend to stimulate the innate feeding responses of a fish and can sometimes trigger breeding behaviors. However, certain live foods can cause needless problems like poor water quality, unbalanced diets, and even certain serious health issues. Below I have listed some common live foods you can use in freshwater and saltwater aquariums: Adult Brine Shrimp: Artemia spp. – As brine shrimp grow to adulthood, their nutritional value diminishes greatly. They are great aid in getting stubborn, picky eaters to start eating, but they should be enriched before feeding. You can use anything from spiralina powder, Selcon (or ay product containing omega-3 fatty oils), Cyclop-eeze, or even crushed up flakes. For best results, fortify the brine shrimp for 8-10 hours before feeding to the aquarium. Always suggest that the customer rinse the brine shrimp before feeding to their animals. Black Worms: Lumbriculus variegatus – In the wild these worms will anchor themselves to the substrate, but in the container we keep them in, they anchor to each other creating a ball. They are high in protein and can help induce breeding behavior in a number of aquarium fish (aka conditioning). Another good treat, but be sure to tell the customer to wash them at least once daily. Ghost Shrimp: Palaemonetes spp. –These little guys can be quite irresistible for aquarium animals. They are herbivores that live in rocky stretches in both fresh and brackish waters (some prefer it). They are an excellent live food that ca also be gut loaded. I feel these to the little cat sharks to stimulate them to eat frozen. It usually works. Feeder Fish: Roseys, Guppies, Goldfish – For certain predatory fish in captivity, this is one of the only things they will eat. For the average aquarium, feeder fish should only ever be considered as an occasional treat and should not become a steady diet. They lack fatty acid that many fish need to stay healthy and can be very messy (causing ammonia spikes). This course does not include every live food available, but you should be able to find these items at your local store. Ask a trained Aquarist to help you select the right food for your aquarium. Good luck in your feeding endeavors!    ...

Unique Freshwater Fish for Sale- The Four-eyed Fish

Unique Freshwater Fish for Sale- The Four-eyed Fish

The Four-Eyed Fish by Mercedes Calabro The Anableps anableps is an incredibly adaptable freshwater fish. Part of the order Cyprinodontiformes, it is related to killifish and livebearers sharing a specialized organ called a gonopodium. Females max out around ten inches and the males reach around seven inches. Anableps are found in tidal waters along the South American coastline, the Gulf of Paria, and the Amazon. In these tidal conditions, their adapted eyes come in handy. Anableps have two eyes on each side of their head that sit on top of one another and allow an extended field of vision while they search for food. During low tide sneak up on small insects and crabs using the set of eyes above water and launch themselves out of the water to grab their prey. When the tide rises they use the lower set to find small fish, snails, and amphipods (microscopic scavengers) below the surface. Anableps are fairly hardy. They need large, preferably shallow, tanks with brackish water and enjoy both open spaces to swim and built up rocks and driftwood to rest on near the surface of the water. Based on the variability of their natural habitats they can handle a pH anywhere from 7.5 up to 9.0 and like the typical tropical water temperature of seventy eight degrees. Based on the size of the tank and how many fish are present, a strong filter is needed (canister filters work well) as they produce a lot of waste.                 Anableps do well mostly in species specific tanks, but are compatible with other, bigger yet peaceful livebearers, and should not be placed with other top-dwelling fish that create too much competition for food as they have no competitors in the wild. Lastly, Anableps have a wide diet including: terrestrial insects, red macroalgae, small crabs, and small fish. So in your own aquarium, there are many options to feed to recreate their natural food sources. A basic pellet should be used for most feedings, preferably one with added spirulina would be beneficial, as they eat it in the wild. Also, Bug Bites by Fluval can substitute for the insects they usually hunt in the wild. Frozen bloodworms, chopped up earth worms, and occasionally blackworms (especially if the fish aren’t interested in pellets or frozen yet) can be used a few times a week for some added nutrition. Overall, the Anableps adaptations make it a very interesting and unique fish that would be a great addition to the right aquarium....
