I am moving around some of my fish tomorrow after some of our fish get picked up and taken off to their new homes. We have 4 red glass rosy barbs that we use as our breeders, 2 male, 2 female, fully grown. They are about 1.5 inches but very active swimmers. I was wondering if the four of them would do alright in a 10 gallon tank? If they can manage it would be ideal for us since that would give us lots of free space for raising our fry.
