One of my friend bout one of them and an Hoplias malabaricus he want to put (them when they will be more big) in his big tank with Pbass and large mouss Bass, he have also an Boulengerella Lucius (golden pike characin).
The bambusa it's not to expensive, ok it's very small, but i think the craziest price it's for the batrachus !! 140 euros !!
