Recently, angelfish and ropefish. Never had a problem with anything else really. The angels though lately have been prone to good ole "fishy constipation". No matter how much I try, I can't seem to keep them alive, and I used to breed them! And the ropefish I get always seem to end up with ich, no matter what I do. So I give up on those two for now.

I bought some zebra danios yesterday. Hopefully, I'll have better luck than I usually do. One already tried to commit suicide by jumping into the HOB filter. Thankfully, the media basket seems to keep them away from the motor.

umm...feeders die the most because they are eaten.
i loose loaches alot too

Same here I can't keep loaches period. I've tried them by themselves in a healthy well established tank and also in a well established community tank. I have no luck with loaches.
