So I've fallen head over heals for dats, I think they're incredible...will small dats (3-4 inches) go okay in a 90 with a silver aro (5ish inches) an ornate bichir (also 5 inches) and a royal pleco (4 inches ish)...They'd only be in the 90 until may, at which point they're moving into a 300 gallon tank
