i have recently picked up a 6" disc motoro ray for a steal, and was wondering what people think to possible tank mates. he is currently with a 5" male argentea, a red tail ruby shark and a couple of plecs. i was thinking of adding a group of geos and a small group of red neck sevs due to the argentea being a soppy ba$tard. but i am stuck on catfish ideas and whiether i can get away with a hystrix and arowana aswell. tank is plenty big enough and water turn over is around 8x per hour.
any help would be great
