Hi everyone. I'm new to the saltwater reef hobby. I have a 29 gallon Biocube set up with about 40 lbs of live rock in the tank, and the bio balls have been replaced with additional live rock for filtering. Stock lighting for another couple of weeks until my new bluefish retro LED system comes in! Currently, I have paired Hi Fin Red Banded Gobies and a pistol shrimp they are partnered with. I've heard that Hi Fin Red Banded Gobies are tolerable of other gobies. I wouldn't mind getting another goby, if possible. Anyone know which other gobies they are compatible with in a small reef setting? I'm also presuming they are not compatible with a blue spotted jawfish in such a small tank, does anyone have a different opinion on that as well?
