So the other day, I bought a betta for my 2.5 gallon tank. In a day or two I will be getting a heater for the tank. And, since the only heaters small enough for my tank, (that I can find) is not adjustable.
So, how should I go about adding the new heater, considering I already have a betta in there?
Will he be safe if I just add it to the tank?
I would prefer not to move him back into his cup from the store for very long. I do have a breeding tank in my 29 gallon that I guess I COULD put him in.... Would that be safe?
Any help would be much appreciated. :)
