Before you buy any fish, you will need to set up the tank. A basic set up includes: a tank, filter, hood/light, heater, gravel and some decor. The tank should run without fish for at least 4 to 6 weeks. This gives it time to cycle. The Nitrogen Cycle is critical to the health of the tank and any fish you will be keeping. During this time, beneficial bacterial will populate the filter and substrate (gravel). These bacteria will be responsible for breaking down fish wastes and other wastes (uneaten food, dead plants, etc.). You will need a home test kit to monitor water chemistry (ammonia, nitrites, nitrates, pH) or you will have to submit water samples for testing. Most pet stores will do this for free or for a small fee. At first, you will see high levels of ammonia and nitrites. Over time, as bacteria grow, these levels will drop. When ammonia and nitrites are at 0 ppm and nitrates are below 20 ppm, you can consider adding fish. Regular (every 1 or 2 weeks) partial water changes as we

The Cowfish, or Longhorned Boxfish, is a marine species that should be kept only by experienced aquarists. When stressed, they can release toxins into the water which may harm tank mates. Pacman frogs, leopard geckos, corn snakes or bearded dragons are all easy to keep.

Check the water chemistry. The discoloration could be due to elevated ammonia levels which can cause "burns". Use a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites with nitrates at 20ppm or less. Perform partial water changes to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. The Neons (blue fish) appear to be infected with Ich, a parasite. Treatment is possible with commercial products found in the local Petco. Follow label directions carefully. You will need to treat the entire tank until all traces are gone. Removing a lump from your fish on your own is never recommended. You can cause severe injury. Most broad spectrum antibiotics (Kanaplex, Maracyn, Maracyn 2, etc.) found in the aquarium section of the local Petco should help treat or prevent infection. Choose one and follow label d

Hello, and thank you for using Boop by Petco. The most common (and easiest) way to clean a fish tank is with a siphon-style cleaner. Fish tanks should be cleaned in stages, generally replacing 10-15% of the water at a time. There are times where a larger cleaning might be necessary, but removing the fish and changing too much of the water at once can be quite a shock and can be dangerous to the fish, so this should be saved for only extenuating circumstances. Here's a helpful video on using a siphon cleaner: http://video.petco.com/v/18852/how-to-clean-your-aquarium-with-the-aqueon-siphon-vacuum-/ And some more reading you may find interesting on general fish tank cleaning and maintenance: http://www.firsttankguide.net/waterchange.php Hope this helps!
