So about 7 months ago I started my tank, a 25 gallon nano. Got past the a fishless cycle, added some coralline algae and then added 5 trochus snail to handle any algae problems. The good news is I haven't really had any nuissance algae problems aside from some light bubble algae. Fast forward a few months and I noticed there were some baby snails on the glass. Great news right? Then I looked at the substrate and noticed there were at least 100 of them, I lost track. While part of me is proud that I'm a successful snail parent, is there anything I should be concerned with other than them having enough food. At what point is it safe to take them out of the tank to give away/sell?
