Chromis?

I'm leaning to Cardinals as well. I was planning on getting one for my 30 gallon, but might just get 3 for the 84 instead. I've read that more than 3 don't do too well together, is this true? Can Banggai's count? Either way, my LFS has both Green Chromis and Banggai's in stock, so I'll see which look the best, and healthiest when I go this weekend.

Thanks for the input.

 

Hi, was just wondering about the dilated eye? why does this mean it will die? i got two chromis about a month ago and one had a bigger eye than the other, two days after one of them dissappeared and hasnt been seen since..
