Hey all, i just started reef tank 2 weeks ago and still cycling untill now, im using live sand from caribsea and liferock from LFS, and suddenly 1 snail appears in my tank in 1st day cycling, im pretry sure it came from the live rock, im worried it wouldnt survived but i have no choice to put it in my 1st day cycling tank, and its still survived untill now (2 weeks later. So does that mean im able to put another snail/hermit crab? Or maybe i can already put some fish?
