hi guys i have a 20 gallon long grow out for my EBJD hes about 2 or 3 inches and their are 5 other F1 Dempsey with him. i put in a maxi jet 400 power head cause i heard if u put them in with a high protein diet he could grow faster and I've done this with other fish and it seems to work, but i know that jack Dempsey don't like to much flow should it take the power head out?
