| Welcome to Fishlore.
To answer your question: No. Bettas are solitary fish. They do not do well with most other fish. Aside from that, one betta in a 5g is pretty well stocked, and you don't want to overload the filter.
I agree with TFA, I wouldn't put any more than one mystery snail in the tank.
You say you'll be putting the betta in after the tank has run a couple of days. Is there a reason you're running the tank? If you're cycling the tank with the filter media switch method, there is no reason to wait (in fact, waiting will be harmful), and if you're using any other method, a few days is nowhere near enough time.
Good luck with everything and let us know how the betta likes his/her new home. |
