i realy like them..... i got one to go in my reef once i put the sump up, because i was goign to drill it and add a DSB, but i decided not to, so there is like no room for him because there is only like 2 inches of sand and all is covered in LR or frags, and id otn want him killing any frags. And i have an orange spotted diamond goby in my 29, so he cant go in there. So im just going to trade him
