Smelly Fish Tank
Dear Vet, My concern is with my fish they are oscars. The problem is the fish tank always stinks. I've talked to the pet store they tested my water and it was fine. They told me that they are dirty fish, and if I have them in sunlight that may be the problem. They eat alot of fish about 30 in a 3 day period. After they eat they sit at the bottom of the tank. I always think they are dying. The main problem is they are my husbands and I'm sick of cleaning out their tank. Do you have any solutions to my problems do I need a bigger tank?
Because of their fish meat diet and high metabolic rate, they produce a large amount of foul smelling feces. If your filtration system is not adequate or the fish density is too high, then the smell does reach intolerable levels. Sunlight also alters the algae balance in the aquarium, and can increase the fishy smell. You may consider a larger or more efficient filtration system, that you clean out more often. Try avoiding direct sunlight to lower the algae levels. If all else fails, consider switching to a non-carnivorous species
