I have only had my betta for about two weeks. Originally he was in a 2L tank which was sold with him, but after further research i found out that they need much more room, so 2 days ago i brought a 21L tank and a silk plant and a heater. I set it all up the heater is set a 27 degrees celcius and i conditioned the water. He was fine for the first day or two swam around and flashed himself in the reflection but, yesterday he was just sitting between the glass and the heater at the top of the tank. I did a water change today, and now he is just sitting at the bottom of the tank on the pebbles... i am worried he is sick or going to die... He dosent have any bloat or fin rot, he looks just as healthy as before. Is it posible that he liked the smaller tank better ?? Should i put him back ?? also there are so many posts about temp i can t really get a straight answer.... Please help i dont want to lose him. :(

Have you started treating your fish? If so, how?
Does your fish have any history of being ill?
How old is your fish (approximately)?

Temp; between 76 and 82. Ideal is 78 for most people. I stay around 78-80.

As for why he's being so still.. he could be lazy by personality, he could be sick. You need to check the tank's parameters and post those, and look at him closely for signs of illness. Check his scales, his fins, his mouth, his eyes and his gills. Fill out that form above and add anything you see.

Make sure he is pooping (easier to do without substrate) and make sure you aren't over feeding him. 2-3 pellets two times a day. If he's little, stick to 2. If you can't catch him pooping, fast him for a day. No food.

There is, of course, the possibility he's just getting used to the new tank, and needs some time. Don't move him back to the other tank, it's way way way too small, but make sure his new one has hiding places like caves and plants, so he feels more at home and safe. Silk or live plants work best.
