I see. I'll be putting that off to a later date.

Assuming i build up my schools, I'd probably be moving one pair of fish to my girlfriend's mother's tank, and completing the school there.

Her tank is 125 gallons, has 2 spotted featherfins, a bristlenose, adopted iridescent shark and bala shark, and an enormous striped convict. Lots of space available.

Any opinion on which school (red glass barbs or columbian tetras) would do better in this tank?
