i do not recommend it in the slightest. even though rays will only take up the floor of the tank, dovii's like ALL parts of the tank to themselves. i think it would end up nailing the ray
Yes I agree. I have a dovii pair. 10in male and 6 in female. Had 3 plecos in there with them and now they are gone. Way to territorial of a fish to keep with anything else. Just keep the dovii as a pair.
