hes maybe 8" now. but has bulked up quite a bit. i just found what he really like, massivore, so the growth rate should pick up. before he was only eating a few cichlid gold pellets and whatever worms he stole from the the cats.
I had some pretty large live plants for several years, now they are all gobbled up and the Brycon has turned his attention towards his tankmates - note to self - Brycon have large appetites and like to Graze get more live plants so he stops grazing on my fish.
