Ahhhh... never heard it called that.
Balas, IMO, don't belong in home aquariums as they get monstrous and have a very large bioload. That said, if you have a tank big enough for it, they're pretty docile while they're small, but get aggressive as they get bigger. They really should be kept with bigger fish like tinfoil barbs, silver dollars, etc.. but only if you're talking a huge tank.
