I got a baby yellow dovii and it is in a 65 gallon temporarely. It will be in a 120 gallon 48x24x24 by itself when I set it up. I think it is a male beacause it was the biggest and most aggressive one in the tank. Well in my opion doviis are overated. everyboudy sys males get 2 ft. Okay some get 2 ft but it is rare. it is hard to find a dovii over 16-18 inches on youtube. So I don't think it will be but some people will...
After reading up to about the 20th page I am considering a silver Arawana to go with my O in my new 48x24x24
