No! Male neon gobies are very territorial. The dominant male will harass and kill all other males. I currently have several in a 40 B and there is constant fighting. On the other hand, if you do get a pair, they will breed.could i put like 2 trios of neon gobies in there, breed them, then stick em in the other tank?
