luckyy, we have like...2 shelves and they throw some in with the tetras that do a huge number on their fins. I rescued Dorito from a tetra tank :)
i was going to get a dragon once but they were like 14 bucks D: and they were all unusually tiny.
I thought tetras were supposed to be good roommates to bettas. What subspecies and what tank g (roughly) are we talking about?
Terrible probably Neon tetras they are fin nippers.
Yes they are but my experience shows that if kept in a school of 10+ they stop that like permanently.
Also space is important. Most species fin nip when they feel endangered. Big schools and large space makes them feel more at rest and stop that behavior.
