Recommendation on Fish Stock

[Pluteaz]

My dad has. Yellow watchman with a diamond goby in a 150. They lived on opposite sides of the tank. He never saw any fighting between them but if you put three in a 90 gallon there probably wouldnt be enough space for all of them

Cool cool thanks for sharing. I still have a lot of time before I actually buy more fish, so my list might really change up. Thanks for your insight :)
