I'm afraid that my sea hare is running out of food in my tank (believe it or not) so today my husband asked my LFS about returning him/her tomorrow... My LFS told him that I should wait until all the algae in my tank is gone (it pretty much is) and then a little while longer, as they can live for several weeks without feeding. This way, we can be sure the algae will not come back. I thought this sounded a little fishy... Do any of you think it will be okay for a couple weeks more, or should I take it back tomorrow? I can't find much info on sea hare feeding online... Thanks.
