I recently set up a 30g saltwater tank for my girlfriend. We let it cycle for a week, I ran some tests and it was ready. So we got our clean up crew all settled in. I've set up many tanks, as I used to work for a fish tank maintenance company. We went to the LFS
and she really wanted these two different breeds of damsels: yellow belly and green chromis. I've never had issues with the chromis before, and I'd never had a yellow belly. I figured they would be fine because they were both babies. This morning, I got a call from her that the chromis was laying on the sandbed. I quaranyined him and medicated him to try to take him out of shock, but we weren't able to save him. He has a bruise on his side and nips on his fins and the yellow belly had been chasing him the night before.
Tl; dr: I'm wondering if anyone has ever had a yellow belly damsel and can give me some advice. Also wondering if it's even possible for two 1-inch fish to even do enough damage to kill each other.
