Ok, So I have four gold fish in one 10 gallon tank. (And yes I know its not enough for them, but its all that I have at the moment.) And one of my poor little gold fish (technically he is a black moor) has been acting funny since I got up this morning. He has been breathing slower than normal and just floating at the top of the tank and when he does swim its erratic and sometimes he swims on his side. I started panicking, and ran the entire test kit for the tank. Everything came out normal except for the ammonia which was just a little high. We have been having some problems keeping the ammonia down. Please help, if this one dies then this will be the second one in the past almost month.
