I have 2 electric blue damsels with some yellow and a tomato clown in my 29gallon high tank It's been up and running for about 2 months now. My question is can I put a small school of green chromis in it maybe 4? thanks cclown
Not unless you want a school of dead green chromis. Tomato clowns- aggressive. Damsels-very aggressive, and in a 29, would be trouble (as well as a tomato). IMHO, very bad idea.
