my betta with a mollie
I've had a lone blue crowntail male betta in a 2.5 gal tank and thought it might be nice to add a friend for him. My local pet store said I could add a mollie so I chose a pretty gold dust mollie to stand out from my blue fish. I started the introduction and new there would be some resistance. My betta would swim up, puff himself all up, then swim off and seem to hide, but repeats this routine every little bit. I'm hesitant to put my mollie in there if it will be bad. How long after I put the mollie in would I be able to tell if my betta will accept him/her? I don't want anyone too traumatized or killed.
