Are these Awaous flavus?
If so, these are freshwater gobies that will tolerate SG 1.005 but certainly don't need brackish water. Short lived, essentially annuals in the wild, so don't buy adults and certainly don't spend a huge amount of money on them. Beyond that, lovely animals. Give them sand: they dig right in, with just their eyes showing -- it's amazing to watch!

I have a 10g lightly brackish (1.005) setup with 10 Bumblebee gobies, and I saw candy stripe gobies at my lfs, would it be possible to have them in the tank?
If not, what is the min tank size for candy stripe gobies?
