I am tired of spending tons of money on fish. I am a college student so money and time are limited and I want to be able to put all my focus and money into my coral. so I was thinking of just getting a lot of different kinds of Chromis and Damselfish. it seems like a good way to get an active looking reef. I have a 90g tank. I was wondering if anyone has done this? and I would love to hear some thoughts on it or recommendations.
