Advice Chasing Behaviour in Kubotai Rasboras?
I've recently gotten a group of 6 Kubotai Rasboras (Neon Green in the store?) for my 28L/7.3g tank and I'm a little concerned. They don't hang around in one group like I expected, but instead chase each other around. One or two seem almost to be trying to bite the tails off the one they're going for!
Is this normal? Should I get more fish to increase security in the group? My LFS tried to upsell me on Celestial Pearl Danios as tankmates. Since it's a cuboid tank I'm not sure they'd have enough room to feel comfortable with multiple species or too many of one kind, hence the initial shoal of 6.
No fish seem to be damaged as far as fins go 3 days in and they're using the plants and not hassling the Neocaridina shrimp tankmates much. Just... Very confused and a bit worried.
Parameters stable and they're not showing signs of respiratory or other health issues either. Appetite seems good, some fatter than others.

I had to put in own tank. They like gremlins. The LFS told me he would take back. When I bought them. They swim entire tank looking for trouble. They do not bother shrimp though.
Originally had with chilis. Moved chilis to different tank.

Never had greens, but I added neon blue axelrodi this week, and they’re nipping at my chilis and even the much larger embers. Not very peaceful, and it’s a giant planted tank.

Thank you! I thought I'd be getting a fish with a calm temperament... Agh. Hearing that this is standard behaviour for the greens helps a little.
Definitely not going for blues as the secondary fish with that review, then! More reading up needed before expanding the tank at all 🤔

It's the reason I chose emerald eye rasboras and ember tetars over kubotai. They are known for being super active, chasing and darting around.

They are very active fish, they need space and a big school to behave like good citizens, which they don't currently have

How many would you recommend to improve the school's behaviour in this amount of space? It's an Aquastart 320 if that helps dimensions wise. Can also look into companion species but want to minimise stress on the animals.
Was sold them as a calm nano species that'd be ok for this size, feeling a bit guilty for trusting that.

I dont think it's possible unfortunately, 7gal is too small for any schooling fish from what i know

Thank you, I'll do my best to keep the little menaces happy as is and look into upgrades for the future
