thanks for the thought, I was gonna get another one with similar size, untill some folks in the lfs told me that its too risky mixing the same species together even in a large tank. Right not I am keeeping my 48cm aba2 in a com tank together with some catfishes. I havent notice the aba2 biting my catfishes yet, with the present of feeders fish in the tank. They always stay piling up in the corner of the tank, and they get really active at night, so I guess I'll keep an eye on them till I get a bigger tank.
