Hey everyone! Looking for some input on adding a second fish to my pico tank (2.5 gallon mixed reef tank). Currently I have a clown goby only and a bunch of coral and CUC. The goby is thriving and eats frozen food daily. I was thinking about adding a fire prawn goby in the future. Currently I’m actually dosing nitrate and don’t have any problems with nutrients building up. I do daily water changes to keep phosphates <0.1
Do goby’s usually get along? I’ve never had the clown goby with other fish so I’m not sure how it would be with a smaller goby. It’s a very small tank obviously but there are a lot of hiding places (about 5 lbs of live rock)
