I have a spare tank and a sponge filter kicking around "just in case"...well today I have my "just in case". I noticed one of my African cichlid's is torn up, bad. I don't know if it's the other fish or his surroundings. They told me at the fish store that I could mix breeds, as long as I got certain ones, which I did...I don't know what breeds I have though I could probably find out. The one that is torn is all yellow. They are all roughly the same size, there is one distinct bully...starting to see now that maybe that wasn't the case, but they all seem to get along fine, except like I said the one bully and now this. I have broken clay pots in there, I don't know if that's what's doing it or not (they are being removed regardless the minute I finish typing this and I'm going to go buy unbroken ones). Anyway, I'm going to take him out and put him in the just in case tank...till he heals or maybe forever?
Anyway, my question. I have a sponge filter for this tank, but it was missing pieces when I got it, used. I think I have it built up as it needs to be, except I'm missing the lift tube. Is this necessary or will it work without it? I'm having a LOT of trouble finding one at the local stores, and can't even find anything suitable at the hardware store. I'm going to put him in there now without a filter, but would like to have one if he's going in for the long haul.
Thanks.

Which I might end up doing anyway, I'm not sure.
