Hello!
I have 6 glowlight tetras, one male giant betta (who is definitely not full grown, currently the size of a standard betta), and a couple snails in a 16g tank. I added the betta about a week and a half ago, under close supervision. Until today, everyone has seemed entirely happy, and then today I noticed my largest tetra go in for a fin nip twice, about 10 minutes apart. Do I need to take immediate, permanent action? Any chance this could sort itself out or remain infrequent? Either sort out on its own or when the betta grows a bit? Or is this just a recipe for permanent betta harassment and/or serious injury?

Oh I guess another note, the tank is planted, though not very established and I would say has a medium number of hiding spots, including some betta caves and a floating betta log. The beta scoped out all the spots when he arrived but hasn’t really been spending time in them.

Ah that is helpful! Do you think it’s ever worth trying them together again (once he’s beefed up and de-stressed a bit?) or is it a lost cause?
