I have a 15-gallon tank with 2 clown fish and a breeder box for the female. I plan to keep her in the breeder box so the gobies can learn where to hide and not go. Additionally, I have a fire shrimp in the tank who has been there for a few months with the clownfish, they don't bother him at all. Is this too much for the tank? My LFS assured me it was fine to put them in but they also said I could swap the female for another if any issues arise. Fingers crossed and wish me luck!
