I've had this 7 gallon lying around for a fair while and I can't stand seeing it empty.
I thought of starting a female betta community or dividing it to get more males but my parents have banned me from getting more bettas.
I am aware that 7 gals is quite small and there are few species that could thrive in it.
I thought maybe a pair or trio of cherry barbs (max size about 2 inches). Or maybe a school of small tetras? Or... I don't know.
What would you reccommend I stock it with?
