Hey I have five 2-3" f1 blue umbees and am currently growing them out in a 125 gallon. I put some rocks, flowers pots and a vine type decoration in the tank for them to have their own territories. There is definitely one boss of the tank. I am currently keeping the tank barebottom with the bottom of the outside of the tank black basically so they can find the food easier when feeding. I was just wondering what the best way in your experience is to growing these guys out. I feed them NLS pellets and beefheart here and there but mainly just the pellets. I would like to grow them out until they get close to 5" and then sell the rest that dont look as good and try and get a pair out of them. I also do about 75% water changes at least 3 times a week. Let me know if you have any suggestions. thanks!
