I have a 30 gallon frag tank, I have a healthy supply of brine shrimp and copepods , I breed them in my garage. I've successfully kept a Mandarin dragonet alive for two years now, first in my 50 gallon tank, and now it's doing well in my upgraded 100 gallon. Keeping pods has never been a problem for me. All that aside, if they are well-fed, is there going to be any aggression between 3 males if there are no females present? I ordered three young Ruby dragonets from a website, I won't say who, but when I requested a male and two females, I was told that it's not possible to identify their sex when they're this young. Upon arrival, I could immediately see darkish green blotches on the ends of their fins, and huge dorsal fins, indicating that they are all male. I could end up putting one in each of my 3 tanks, but I'm curious if anyone has had any experience keeping only males?
