Unhappy I am new. Why is he doing this?

My male betta is acting odd. I have him in a 2.5 g tank with lighting. He has moderate hiding space.

2 days ago I put new gravel in and did an 100% water change. He seemed fine. This morning I feed him some BettaMin flakes. Now he looks bloated and is floating on his side. At first I thought he had died but when I put my hand on the side of the tank he tried to swim downward but floated up. He did the same thing a few weeks ago but after a day or two it would go down and he could swim again. What am I doing wrong? Is there something I can do?

It's hard to feed the same amount of flakes consistently so it might be an overfeeding problem. I'd recommend switching to pellets. Feed 2-3 pellets twice a day for six days and fast the seventh. I would fast him for a day for starters. (I'm not sure if the floating is just bloating that will go away or if you need to treat him.)

A heater is going to help your betta as well. They are tropical fish and are best suited to 76* to 82*. Your current temp is pretty chilly. Is he fairly inactive and lethargic? If you aren't sure what kind of heater to get for your sized tank, just ask. Also buy yourself a thermometre to put in the water; they are only a dollar or two. :)

Good luck!

I will try the pellets. What brand do you suggest? Also is there any good heaters for a 2.5 g?

You are supposed to put additives to regulate the water.

I used to have same problems in the beginning, now I feed hikari micro wafers 2 in the morning 2 at night (sometimes couple more), one day fasting and switch with daphnia or bloodworms for a treat and I haven't had problems for a long time now. Since he is bloated, you could tray daphnia first, it also works as a laxative.

You may be ok if you let water sit for 24-48 hours (to get rid of chlorine) but I still add conditioner anyway to help neutralize heavy metals and then let it sit for about 24 hours.

Blazer makes a good point too; your water should have a water conditioner in it when you add it to the tank. Prime is a popular one (a bit more expensive but more concentrated so you use less). The water conditioner helps remove chlorine and other tap water ingedients you don't need. (But tap water is best because there are some good minerals in tapwater.)

For food, I feed my guy Topfin Pellets. I feed 3 pellets twice a day, fasting Fridays and on Sunday, I feed 3 bloodworms instead of pellets for the first feeding. The fasting helps their digestive system.

My tank is a 5G so I don't know about the smaller heaters but someone else here will. :)

For a 2.5 gallon, a 10 watt heater would probably do. It sounds like he is eating too much and it is making him float like that. I would also suggest pellets, i am currently using Wardley Betta food pellets. They have been working for me since i got them.

I have a marina 10W for my 2.65gal (10L) however it is a preset one so it is not as reliable. One you can adjust is preferable, and a thermometer to go along with it. My Scuzi did that once after a water change, it wore off after an hour or two.
