My research hasn't been very helpful. I'm interested in adding both a purple and orange firefish to my 75 gallon. I know two of the same type may fight unless they are a mated pair. Will one purple and one orange fight with eachother? Anyone with experience?
I went through the exact same dilemma a couple days ago. I got a small 16g nano and had my purple for a couple weeks as my only fish. I just added the red firefish a couple days ago and was nervous but they were fine. They each have their own caves, eat together and haven't fought. My buddy did the same but he has a much bigger tank and his share the same cave. Its only been a few days for us. I read others killed each other. So in the end, its a matter of personalities really, roll the dice!
