The night before we got my Betta fish I put tap water in my tank and put the conditioner in, put in decor, substrate, and then I put on the filter and heater. Then we got the fish and when I got him home I put in safe start by tetra not the plus. Then we let him acclimate for 2 hours then we opened the bag put 3 Dixie cup full of the tank water in his bag every 10 minutes for 30 minutes then we put him in the tank. I have noticed he is hanging out by the heater. He has been swimming around a lot comming to me but he is by the heater. I don't know if this is normal. My first fish that I got a couple of days ago hung out by the filter a lot and then the day after I got him he died. I used Betta water and then just poured that in the tank and let him acclimate for 20 minutes then put him in but I don't think the water was warm enough because he acted weired. I did not have a heater and the water was cold. I didn't understand what the pet store person told me. She said the water was ready to use right away and you don't have to do anything. And because he died I am never using Betta water again. So I used tap this time. And the conditioner. But he is hanging around by the heater and I am really scared I really want some insight. To see if that is normal.
