I have a datnoid and I'm just wondering if they are better kept in groups. I had three but i lost one to ich back in october and i lost the other one a couple weeks ago from his fins bring nipped too much. The one i have now is about 2" and hes in a 180 gallon tank. Ive had the one i have now since last august and ive notixed no growth and I'm just wondering if He would be better if there were a group of them. Hes a pig and hes just not growing. If they do better in groups how many should be kept together? Any help is appreciated.
