hi guys,i have a problem with the kids tank in that the smaller fish keep disapearing,,there is a large angle in there as well as a 5 inch black pleco and 2 gourami,,would any of these fish be responsable??about 5 fish have gone now with out a trace,,cheers chris

The same thing happened to me a few months ago, I got a 20 gallon tank that had various small fish such as tetras and a few small barbs. A couple of them just disappeared totally, never found them, didn't even find any bodies. It's very strange. I think that your plec could possibly be responsible. A lot of these are nocturnal so active at night whilst other fish are sleeping. Something may have happened and he could have eaten them. However, the finish could just be somewhere in your tank only haven't found the bodies. How do you clean the tank? Are you quite sure you haven't sucked them up when cleaning the tank?

I don't think anyone can really answer your question. It is one of those things that is going to remain a mystery, maybe you'll solve it one day.

Hehehe .. this one sounds familiar.
In my daughter's tank there was the same thing happening sometime ago, she had a group of small tetras in there. I had to put an angelfish in temporarily, and during that time, the tetras went missing although we never witnessed any chasing or hunting. So my bets would be on that one. Only had plecos in there though that were smaller than yours so I wouldn't say I'm sure.

i just use a vacum pipe to clean,,all iv ever found is part of a tale.the kids kept blaming me for feeding them to the oscar (haha),are any of those larger fish aggressive,or are they alrite as community fish?

so metoo do u think it may be the angle? its about 5-6 inchs from top to bottom,,all the fish know to stay away from him as he will chase them aroud the tank for a couple of secs

you've got an angelfish?, I did wonder what you meant by angle. Well they do say don't mix angelfish and Tetra like metoo has already mentioned, I think that possibly could be your problem.
