Yeah, these are great fish! I want to start a colony soon but limited tank size means I can't do it yet. But be careful if you do try to breed them, one person I knew started out with 10 fish, 5m/5f and had over 400 endlers in her 75 gallon tank prior to losing all but 4 in a power outage. Plus, she would scoop them out every couple of weeks and take dozens to the lfs.
