I treated my 90 gallon tank with prazipro on the advice of a fish store and afterwards 3 angelfish showed signs of being unable to breathe and died. This tank had two filters and a bubbler so it seemed unlikely that the oxygen was depleted enough to kill anyone because of the medication, but that was the only change made. Days later, in another tank which was not medicated I have two electric blue rams gasping for air and all the snails in the tank have crowded at the top. Obviously they are having trouble breathing .. but why? There's 0 ammonia 0 nitrites and less than 20 ppm nitrates. I'm thinking some kind of bacterial infection which was spread between the tanks by the fishnet. I'm not sure how to treat and it seems 2 out of 4 of my tanks has been infected. Please .. advice
