I had thought to maybe treat the tank with erythromycin. And this is definitely not BGA. Its white & fuzzy. Its not rampant, but is more noticable around the edges of the suction cups. Its starting to grow on the driftwood again.
For the record I'm only using a sponge filter, not a H.O.T. filter. I wouldn't expect this to be the cause. In any event it sounds like I should remove that driftwood. This won't leave many hiding places for the pair of Apistos I'm trying to breed. Think they would get along with my female Nijsseni in my 32G comminity tank?
Could this be insufficient biological filtration? All I have is a sponge filter in the corner of the tank with an air pump attached to it (its only a 5.5 G tank). Is there possibly not enough water movement?
