I've had some male guppies in my tank for about a fortnight. They are the delta variety; 2 b&w, 2 blue/lemon and 2 red/black.
The two red/black ones are dead (along with some of the endlers - even female ones) and I noticed that their tail fins have been munched on quite viciously. Now, I'm not one to point the finger but one of the blue/lemon guppies seems to have quite a distended belly - if he were a she, I'd swear it was pregnant!
Anyway, do you think I've colluded unwittingly in a bit of interguppy bullying? Also, will they start picking on the other fish now as well?
Might have known Chelsea and Newcastle would not be able to refrain from violence when contending with Man Utd!
