So yesterday I went out and bought a 2.5 gallon tank and an awesome dt betta. I set up the tank, added the water treater, and then acclimated him by letting him float in a cup in the water and then pouring some of the new water into his cup. When I finally put him into the new tank, he swam around a bit, but then went to the corner behind one of the plants near the surface, and hasn't moved since.
At first I thought that he was just resting cause it had been a big day, but this morning he is still in the exact same place with his fins clamped. He doesn't move except to raise his head to get some air. I tried feeding him but he doesn't pay any attention to the pellets.
The only thing that I can think that I am doing wrong is that I don't have a heater. I tried to buy one from petsmart and petco, but they were both sold out. I checked the water temperature though, and it's at 73 degrees.
Should I be doing somethinge else? I don't know the parameters, but I can't imagine that the ammonia or anything is high considering the water is all new from yesterday afternoon. Sorry for the long post
