Ive got a 300 gal with 2 black rays 12-15'', 1 16'' silver arowanna, 1 10'' prochilodus, 2 5'' red spotted severums, 1 6'' black ghost knife, 2 small Dats, 1 synodontis angelicas. I want to get into PBASS now. what would be the most recommended type without breaking the bank too much? most popular when it comes to colours etc? i understand its best to keep 3+ to avoid too much conflict? any and all input is greatly appreciated. Thanks
