I recently purchased a lipstick goby from Invertz Factory and later read that they don't care for the levels of CO2 found in high tech tanks. My goby starts climbing the sides of the tank whenever the CO2 is on and the only low tech tank I have is my blue tiger shrimp tank. For obvious reasons, I don't want to risk the goby munching on baby (or adult) shrimp but would prefer not to have to get rid of him. Is anyone keeping these gobies with shrimp other than RCS? The reason I specify RCS is because I think most of us agree that it isn't too big of a deal if we lose a few RCS but I hesitate to take the risk with my $10 a piece blue tigers.
