Seahare woe's.....If the tank water isn't purple you are probably ok..I have had a couple of incidents with seahares..I finally put sponge around all my intakes and no more sea hare accidents..works well with anenomes too. My son's tank went all purple when his seahare got caught in an intake..as for toxins..hard to say how it would affect it as he transfered all his livestock very quicly in to another tank..he did some water changes over the next few days and all the stuff on the rock was fine..no worse for wear..so unless a member has had a massive die off I dont think I would panic just yet..Do a partial water change and if you dont have any put some charcoal or chemi-pure in a filter...good luck..
