Hey I'm having two small problems....the first is my sixline wrasse has been pestering my two brand new peppermint shrimps....the next is I noticed I had about 2 very small white snails...hitchikers of course..well now there is alot more....I also noticed alot of them on the glass near the back of the tank...not snails yet though, seems like the babies or something...should i be worried or are those snails beneficial to a reef tank...
