Just wanted to get some opinion on this. My tank is probably 3 and a half months old right now. So far, I have a Fasle Perc, a Green Chromis, and a Firefish. Eventually, (in the near future) I want to add a Yellow Watchman Goby and Green Clown Goby to the mix. Would this be too much for a 24 gallon tank? Both gobies are fairly small. Any thoughts?
