Re: Tank size to rainbow tetra

Hi, Nichlau. Thank you for your question and welcome to the Petco Community. Three Tetras may be okay if they are under an inch in length. But this would depend on the size of the Tetras. You can find some great information in the community here: https://goo.gl/bVvC1D. We hope this helps!

I'd say 5 or 6, just make sure your tank is cycled before getting them to avoid casualties.

Please read if you don't know about cycling an aquarium: https://www.fishtanksetups.com/best-aquarium-filters/#Biological-function

Hope this helps!
