I will be getting a 120gallon (my first monster tank) with my bonus at the end of the year. Currently I have 4 tinfoil barbs in my 55 gallon, they are about 3" now, and was curios on how big they will be by the time I get my 120 (January next year). Everywhere I looked says they grow relatively slow like bala sharks, but they eat like crazy. Also what are some good tank mates for them when I move them?
