I have a Fluval spec 5 it is nearly done cycling, and am now preparing to make a list of what I need to stock it. I was thinking when it's done cycling on adding 2 red legged hermit crabs, and possibly a tronchus snail.My question is, is this too much for such a small tank, will there be a shortage of algae for the 3, and on that note do I need to provide supplemental food for the hermits while tank is empty of fish? My live rocks have some algae growing on them, but not a huge amount, and my glass is clean
