Well my dream of a big dovii tank just seem to unrealistic for years... I recently have found a possible solution I am very interested in a black nasty pair I watched videos on them and they are just stunning fish and have a lot of qualities of dovii in a smaller package but not small what I have read so far is males can reach 16" but more likely 13-14" I don't know if that's true or not. I have read they get bloat easy and are best on a more plant matter diet with low protein. How low exactly? And what's a good pellet for them? Also read they like a little warmer water and need extra aeration and pristine water. All of that I can handle I am very diligent on water changes. I seen a male on YouTube housed alone in a 90 gallon tank that was about 16" and appeared very healthy. My question about tank size is would a 125 work for a pair? It would seem like the 18" deep footprint wouldn't be large enough but the one I seen seemed to be happy and fine. Also where can I find nice quality pairs online? I've never seen them for sale locally. Basically anything I should know let me know I have been reading and watching as much as I can but I'm sure keepers on here can tell me more. Thank you
