What size is your tank? 1 gallon (planning to buy a bigger one once I get paid)

What temperature is your tank? Not sure the water is usually lukewarm (planning to buy a stick on thermometer once I get paid :/ )

Does your tank have a filter? Yes

Does your tank have an air stone or other type of aeration? No

Is your tank heated? No, but it does have a light and I heard it does warm the water up a bit.

What tank mates does your betta fish live with? He's alone.

What type of food do you feed your betta fish? I just started using Hikari Betta Bio Gold pellets. Before that I used flakes.

How often do you feed your betta fish? Twice a day. 3-4 pellets and the flakes 1-2 when I used to use them.

How often do you perform a water change? once a week.

What percentage of the water do you change when you perform a water change? I take out 75%

What type of additives do you add to the water when you perform a water change? Nutrafin Betta Plus (contains almond leaf extract, if that matters)

Water Parameters:
Have you tested your water? If so, what are the following parameters? N/A


Symptoms and Treatment
How has your betta fish's appearance changed? He was bloated as if he had dropsy however within a couple of minutes after I noticed the bloating he'd become skinny again.

How has your betta fish's behavior changed? Nope, still curious and active as ever.

When did you start noticing the symptoms? The first bloating was a couple of days ago. He was extremely bloated last night however after 5-10 minutes he was skinny again.

Have you started treating your fish? If so, how? I've decided to fast him for a day or two because I'm starting to suspect that I've just been over feeding him.

Does your fish have any history of being ill? Just barely got him.

How old is your fish (approximately)? I have no clue, but he seems to be very young. Probably not even a year.

Also, I just bought him a red silk plant and I saw him resting on it. Is that normal? I'm very scared for him. I don't want him to die. I read up on the bloating and I'm starting to think it's just constipation and overfeeding.

Hi Lovely,
Welcome to the forum.
What do you mean by bloating? Just want to make sure as we sometimes have different definition for it. Did your betta's underbelly just swell up, or the whole body bloat/swell up? Is it possible to have a photo of this when it takes place? I personally have not experience this instant bloating, and instant skinny type problem before, so hopefully someone else can give you some insights into this.

For a 1 gallon, the least you can do is 100% water change twice a week to avoid any poisoning of the unwanted chemicals. This is slow acting and your betta is silently suffering, and sometimes it's not reversible over long period of time.

Good luck and keep us posted!

Yes, his underbelly was bloated. I fasted him for a day and he's completely better now, I hope. He's perky and it looks like he's making a bubble nest. I bought some epsom salt just in case I face this problem again. I did notice a poop when I was cleaning his tank today and I'm starting to think he was just constipated.
