So yesterday I bought some fishes for my 125g. I got 3acei, 1 yellow top mbuna, 2 red shoulder peacocks, and 1 nyererei red. This morning I went down to see how things were going and I couldn't find the nyererei any where.

I looked on top of the tank under rocks and he was gone

! Then I looked in the overflow box and there he was swimming around

. So i fished him out and now I have to figure a way to keep this from happening again. for now I stuffed some filter foam in the top hopefully that will help until I have a permanent solution.
