I talked to the LFS and brought in the dead firefish and they explained alot to me, and it turns out it wasnt ick. To save time typing, my progress thread is in this forum and it has it all laid out in there.
The LFS lady said with firefish, the first 48 hours or so they can be quite jumpy. They try to escape by jumping alot, or trying to fit into places they really dont fit. Thats the case with mine. It didnt have ick, but it was wedged under my LR. It mustve been trying to dig a tunnel or something or find a good spot, and the LR shifted, and splat. Its not a bad fish, but just jumpy at first. Supposedly Im one of the only guys who've ever killed a firefish at my LFS, and as far as Im concerned it killed itself!
