Ok, to be clear im classifying a nano tank as 30 an under. Is that technically correct… no idea. But my favorite has to be a shrimp goby pair, preferably with a dracula goby
I'm still trying to find something to put in my 10 gallon mixed reef. It needs a fish in there, but I just can't decide what I want in there. I really wanted a yellow clown goby, but with the SPS that is in there....
