@Cory @Ben Ellison I keep her in 55g. The only fish she bickers with is her male partner. It is a bit of a busy tank with 5 adult Dwarf Neon Rainbows, 2 juvenile Dennison Barbs, three adult Yoyo loaches, a breeding colony of Hillstreams and 3 Rummy Noses.
Once my 14 female bettas in my 30g are quarantined I can move her in with them. That would be quieter. Or I can remove the male to a 35g male guppy tank immediately. Would removing her mate cause more or less stress I wonder?
