According to what I have read, these fish will do best in full salt. They can live in about any water, but are much more prone to disease in FW
. They also don't live as long in FW
. I'm going to try to ease the SG
up to about 1.019-1.020 and see how they do. I've read, as long as you keep them well fed, you can keep hermit crabs with them and they won't bother them. They sure do like snails though!
