Anyone else having these issues? I added the amanos and within two weeks found my two smallest corys dead. Nothing else in the tank has change, I did move my betta in there because his tank got redone. But his too slow to even touch them.
Also just because the betta couldn't catch them, didn't mean it didn't harass them to death. Some betta's are relentless, especially after the lights go out. I've had fish with a betta, seemed fine, lights go out, dead fish in the morning.
20g platy, , 2 x 10g shrimp, 3 x 20g shrimp, 7.5g shrimp and 1 great dane/mastiff puppy.
