I just got a betta fish today and have an important question?


I got a betta fish today and he came in a cup. The cup has blue water in it. Is it ok to add the blue water to my aquarium?

I would not. That blue water is medicated because of how stressful being kept in a cup is for a betta. Being kept in such a small volume of water without a filter or a heater makes them prone to sickness.

I would dump half that water out and replace it with half of your aquarium water after you have allowed the cup to acclimate to the tanks temperature. Then net the betta out and add him to the new tank.
