I've noticed lately, (since my snail died) that there is now and abundance of what I assume to be some kind of Algae. Not sure if its one to keep or not, so thought I'd ask. It covers most of my rocks and looks 'wispy' but doesn't quite look like hair to me. I'll up load a pic. \n\nAlso, in the algae are tiny larvae. Not sure if it was left by the snail or if its from the crabs. We haven't had fish in there for at least 5 to 6 mo. (no luck with them yet) so either the crabs got it on or the snail got busy with him/her self. Trying to figure out what they are and what I should do about it. \n\nThanks so much!
