oh one last quick question , it involves aquarium janitors how many should I have in my 10 gallon I read 1 snail every 2-3 gallons does this also apply for crabs or are they counted as they same?
right now I have
3 trochus snails
1 unknown (he's green with dark blue eye stalks) I don't buy things I don't know anything about but my buddy wanted something in my tank so he picked him out.
and 1 emerald crab that hitchhiked in on the live rock, pretty good deal considering there 15.00 a pop at my LFS
I know variety is the spice of life so possibly a couple diffrent snails?
