Learn how to care for Marine FOWLR Aquariums. These tanks have easier upkeep and require less testing and supplementation than a reef tank. You can keep many fish who would generally consume corals and invertebrates, making it a popular setup choice for more aggressive fish.

Check the water chemistry. Confirm ammonia and nitrite levels are 0.25ppm or less and nitrates are 40ppm or less. Use a liquid test kit or submit a sample for testing. Most pet stores or aquarists will do this for free or for a small fee. Partial water changes, about 30% can be done to decrease high levels. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. My preferences for water conditioning are AmQuel Plus and NovAqua in addition to StressCoat. Confirm water temperature between 78F and 80F. You can soak pellets in some garlic juice to stimulate his appetite.

I'm sorry you are having difficulties with your aquarium. There are several issues that should be dealt with right now. They are water chemistry, aquarium size and choice/number of fish. Any new aquarium should be set up and, ideally, run empty for several weeks (usually 4-6 weeks). This is so beneficial bacteria have an opportunity to populate the substrate and filter. These bacteria are necessary to break down wastes that fish will produce. The technical phrase for this is "establishing the Nitrogen cycle". These bacteria will break down wastes into ammonia then nitrites then nitrates. Nitrates can then dissipate or be absorbed/used by live plants. In high enough concentrations, ammonia and nitrites are toxic and can kill fish. Cycling a tank with fish is possible but it increases the risk of loss. Water chemistry should be checked every few days using a liquid home test kit. A water sample can be submitted for testing , but is not as convenient as testing yourself. Most pet sto

First, perform a partial water change, vacuum gravel thoroughly and wipe down any tank furniture. This is critical because clean water is the cornerstone for treatment and recovery. Use only conditioned water that is temperature matched to prevent stress or shock. Next, you can use any one of the commercial ich medications, such as Ich Guard (Tetra), Super Ick Cure (API) or Rid Ich Plus (Kordon). These can be found in the Aquarium section of the local Petco. Follow label directions carefully. This method will typically work with most fish. Another option would be to use plain aquarium salt ( NOT table or Epsom salt). Dissolve 1 tablespoon of salt per 5 gallons of water in a cup or two of tank water and gently pour it into the tank. At the same time, gradually increase the water temp to about 86 F. Hold it there for 14 days. The warm temps will speed up the life cycle of the parasite and the salt will kill it. Afterwards, gradually reduce water temp and perform another partial water ch

Yes it is possible, however, unless you have a lot of experience keeping saltwater fish, please do not even attempt it. Most wild caught saltwater fish will not feed when they are in an aquarium, and only a small percentage will ever learn to feed. Please leave them where they are happy and healthy and where they belong, the sea.

If it is on the glass, remove enough water to drop levels below the lotion and wipe with paper towels until clean. Avoid soaps or cleaners which can cause more harm to your fish than the lotion. Replace water with aged or conditioned water that is temperature matched to prevent further stress or shock. Use a fresh carbon filter insert to remove any residual lotion or chemicals. If the lotion is on tank furniture, remove and wash with a mild soap then rinse very well before returning it to the tank.
