Hi I have a problem . I have a 55 gal freshwater tank. The fish I have are 2 upsidedown catfish, 2 playts, 1 irredescent shark, 3 yoyo loach, 1 weather loach, 2 kuhi loach, 2 sunburst gourami, 2 silvertip tetra, 1 pleco, 2 silver hatchet, 2 angel, 4 bumble bee, 2 tiger barb, 2 octocinclus algae, and disappearing large neons. One of these fish are eating the large neons. I had 1 neon that lasted when we started the tank, I purchased 8 more but they were pretty little they all got ate but 1, so I purchased 6 large ones, 3 were missing, the next day there was only 2 left but one was in the plants with a big bit out of it's stomach. WHICH ONE IS EATING THEM.

Upside down cat fish & pleco has trouble w/ the bumble bee... semi aggressive

What kind of neon fish is it?
Neon tetra
Blk neon tetra

My bet is on the angelfish.
They are quite nasty little beggers, mine eat all my neons.

Yup your right...
I read that post twice and never once seen the 2 anglefish.

If the angles are kind of large they will eat small tetras. Mine are old and large and eat all newcomers to the tank that are very small. Tetras should be kept in a separate tank till they are about an inch or so.

If they just die over night the Pleco will eat them off the bottom. Also, how large is the irredescent shark, he could also be part of the problem.
