Generally Crenicichla have a rediculous growth rate, lol. They have to grow faster than most fish because they are predators, and in order to eat other fish, you normally have to be larger than them.
Which species of Crenicichla are you thinking of puttin in with your bichirs? Thats the really important question. If you were goin with Saxatilis group pikes you could get one now and put it in there. If you were goin with Lugubris group pikes you could still get one, but I'd aim for one in the 3" range. LoL
