Should I add one more

[ll206]

Hey guys, I need a professional opinion on this one. I have a 40 g FO; with a baby cowfish, an ocillerus clown, a maroon clown, a watchman goby, a firefish goby, a fire shrimp, and a mushroom rock. I want to add one more fish. Help please?

You might be able to get away with one more fish but depends on which one you get. You should get a small to medium sized fish. But if your water quality starts going all crazy then you should probably take one back.

it kinda depends on your setup. if you have a good skimmer i would think it would be ok to add a small fish. but you will want to be careful with the cowfish. ive heard that they actually let small amounts of poison into the water. all the fish in your tank will grow used to it, but a new fish will not be yet. also i dont know how big a cowfish gets. another thing to watch is the clown fish. ive read that the maroon clowns can get quite aggressive towards other clowns.
