Small, look like snails w/o shells, some are brown and tan, other ones are dark grey with with spots, could they be sea hares, and if so is it allright that I saw like 5 of them in my tank? Any help would be great thanks.
There are so many small creatures, there is no telling without a pic. Is there a possibility they could have soft shells or a small shell that does not rotate? Are they long and slender, round, or oblong?
and that they do I think I have about 25+ now. Most have gotten pretty big and are comfortable unough to come out in the afternoon to clean rocks and glass.
