yeah, joshua was my fault... listened to several LFS guys...put the betta in the tank, watched them for about an hour and a half. All was fine.
Next morning was a different story.... he had attacked two of the three pladies... bitten off part of their tails... turned out joshua got the worst of it, he had also bitten his mouth, and he was unable to eat but small morsels... guess it was not enough for him.
I feel really bad about that. My wife made a little coffin out of a box and we buried him last night under my daughter's tree with a goodbye note.
