I have a few chili Rasboras and some tangerine caradina shrimp in a 3 gal tank. I'm careful how much I feed them. They are active and seem ok, but they seem skinny to me. Do they look ok? See video below
Never have had them and don’t know a thing about them but all the pictures I’ve seen of them tell me that they are a naturally slender fish . They look active and alert and that tells me they are healthy . As long as they eat good and stay lively I wouldn’t worry .
Seems yours aren't fully grown yet
It's normal for them to look slim when they're young
As everyone said they are a slender build fish so don't worry they'll do fine
You can give them a high protein diet with something like spirulina to help with their growth and also to boost their colouration
I can't see much of the tank setup from this video but I hope it has plants and driftwood making the tank comfortable for them
