Curious, but how many of you have kept dovii with tank mates? Type? And for how long? Much to my surprise, I have a 10 inch dominant male and 5 others ( 2 other males, and 3 females) just a bit smaller. 2 fire mouths, 2 silver dollars, and 3 plecos in the same tank for well over a year with no casualties. Nothing even close either. Not my first go around with dovii. Every other dominant male I have kept will barely tolerate his choice females, let alone other males.
