seahorse

I went to the painted horse in orem on saterday,and they were taking down all of the tanks. They are going on the internet only, anyway all the tanks where dead or dying and I found a seahorse among the waste with some crabs that were still alive.I ended up getting them (I felt sorry for them the heat and pumps had been off for a week).He is getting around allright but so far has not eaten as far as I khow. I have a fair amount of bugs for him and he could be having them I just havn't seen him eat. Is there anything I can do to save him? I have brine shimp hatching now.
