Would bettas fit in?

[Lili]

I have a 32 gal planted tank with 6 cories, 5 guppies, cherry shrimp, an assasin snail + pond snails and a pearl gourami. I love Betta males but I wouldn't want to risk him decapitating all the other inhabitants. I saw peaceful veiltails in my LFS that lived with cories and lots of community fish. Shopkeeper told me they wouldn't harm my fish.

I am also planning a 6 gal betta tank for my mother, would any tank mates fit in? I want a nerite snail there but some additional fish too if possible.

probably no fish in the 6 gal but invertebrates could work

It’s a good rule to not mix bettas with other labyrinth breathers (gourami) due to aggression from either party.

As for the 6gal, I say no other fish with a betta in that size. Shrimp (may get eaten) and snails are all I’d try. 10gal minimum for betta communities and even then choices are really limited compared to larger tank sizes.

Shrimp in the 6 gal could work if they are in first. If the betta goes in first he views them as intruders in his territory and more often than not with kill them all. Might not even eat them but they'll be dead. Also a betta with more finnage like a halfmoon or over half is going to be slower and find it harder to chase the shrimp around so they'll be safer. I had shrimp in a 5gal with a plakat betta and he shot around like a rocket catching every last one.
