I just got this 29 gallon fish tank (a stand, heater, and filter 2) 4 christmas and upgrading my female betta tank. im gonna put her w/2 other females and thinking of putting them w/neons. so will neons work w/bettas.
I am not an expert on the cycling issue. But with regards to the compatibility issue, I have a female betta who has never even flared at my neons and the co exist and live peacefully in a 10 gallon tank.
Depends on the personality of the betta. My prior betta, Rocky, was fine with tankmates. The current Lord of the Betta Palace, Louie, hunted his roomies to extinction. :irked:
As far as Neons go, I think they'd be fine with female bettas, though I might be concerned about them being tempted to nip a male's long fins. I doubt it's much of a risk, however. Neons are pretty peaceable.
