I'm kinda in a bind I just found another Cory dead. The first was a small spotted I thought he must have just been stressed or something and passed but now almost a 2 inch emerald was found. The thing is they were found with no fins completely eaten.

My question is the only possible aggressor has to be the 4 yoyo botia any 1 else have aggression issues with them?

Okay:
What kind of cories are being killed here? How big is the tank? What other fish are in there besides the yoyo loach?

54g

1-spotted or peppered
1-emerald green

Other than the yoyo's are a peecock eel clown pleco a rainbow shark, and an elephant nose.

I'm positive it's not the rainbow cause he's so docile.

Sadly it must be the yoyo's they've gotten nippy with my angels.

Just wondering if anybody else had experience with this aggression.
