It had good extension in the prop tank before the lights went out, so I think it will do jsut fine until the new main tank gets set up. I have another blue/tan crocea in there that has been in the prop tank for going on 5 months now (I think, maybe longer, I don't remember exactly when we got it
). I built an 18" square "sand box" for a variety of reasons, the clams are it's current residents (the 2 croceas and the large deresa that we got from Xia today). The only other inhabitant is an open brain that is more comfortable on the sand than the frag racks
