I just go tone of these in the shop I work in. I really want to take it home before someone buys it and throws it in a low pH freshwater tank. But I have small Brackish blennies, leaf fish, and a knight goby that would all be tasty morsels for it

.
I could set it up by itself in my 10 gallon brackish tank as the current inhabitants are all basically big enough to go into the larger tank, but ill then have to figure out where to put it before it outgrows the 10g, lol.
