Black Neon Tetra's Have The Munchies

[ecro83]

I have a 30l biorb with 4 black neon tetra's. 2 dalmation mollys, and i did have 2 guppies.
I went to my tank this morning and one of my guppies has disappeared, there is flesh parts visable floating around the tank.
THis is the 2nd fish to have disappeared and disintigrated in my tank as i also had 4 blue neon tetra's that were munched at over night as well.
I have noticed that my tiger molly's tail looks a little nibbled, so im thinking whoever nibbled on his tail is the culprit as to who ate the other fish!
Anyone have any suggestions? Have you ever heard of black neon tetra's doing this?

I can't imagine that Black Neons would be the problem. Mollys can be nasty, though. I think that fish may be dying, and THEN get eaten. You have a LOT of fish in that little tank. Is it cycled? Have you checked the water readings?
