So i had my pair of dovii and my female red tiger mota in the same tank, a 40 gallon breeder since they were all around 3.5". It appeared my female mota was attacking the dovii as she was the only one with no battle scars and the dovii were both a little battered. Assuming the mota was responsible i took her out and gave her her own 55 gallon tank(she hasnt eaten a thing since) and the dovii pair is no longer a pair. One of them killed the other. So im just having the worst luck with the restart of the fish room. Only thing doing good are my oscars and azuls which will soon be going into a 1018 gallon pond.
