After finally finishing my fishless cycle I added fish on Sunday afternoon. This afternoon my betta has a white fungus on his mouth. I have had the betta for 3 months and kept him in one of those small "betta" tanks and he was quite happy and healthy... Put him in the 29 gallon with 4 peppered cory's and 10 neon tetra's on Sunday to populate the newly cycled tank. I lost one neon tetra by the next morning and assumed it was stress/rough handling by LFS, didn't notice anything on him after we removed him. I have moved the betta back into his small "betta" tank. Have looked at the other fish in the 29 gallon and don't see anything unusual... Also have sent my Husband to the LFS to get some Melafix... My big question is... Should I treat both the betta tank and the new big tank? Will it screw up my biological filter? Anything else I should do?
