Hey everybody, I am new to this website and I was wondering, how many watchman gobies would be able to fit in a 55 gallon tank, I am thinking about a few different species such as yellow, pink spotted, common, and orange spotted. I don’t have the tank yet but I will soon. I will also have a bicolor blenny and a fanged blenny. Correct me if I am wrong but I am pretty sure fanged blennies (Midas, striped, etc) can live with comb tooth blennies (lawnmower, bicolor, sailfin, etc). So please let me know
