From what I have read and heard from those that breed Beani, is that they do not have a fully developed stomach to help with digestion. Which makes it more difficult for them to digest large amounts of protein and food. Feed him a low protein diet, I would stick to flakes only until he is 3-4", and feed him once a day. Stress does not help either, so keep the temp consistent and the water clean. It wouldnt hurt to install a UV on that tank.
Good luck. This is just what I have learned. I tried for a year to grow them out without researching more in depth. That was a poor decision on my behalf. Now I have a 4-5" beautiful male that is growing more and more beautiful each day.
