That is so true.Do you soak the pellets in tank water for a minute or so? That is good prevention
They will almost definitely suggest you buy medicine.I pre-soaked his pellets last night and fed him- breaking his fast. This morning I turned on his light and his stomach is definitely distended, and worse than that, he's starting to have trouble swimming.
Heading off to the LFS for some daphnia and hopefully someone there will have more ideas on what to do.

Please come back here and ask others before dumping a bunch of medication into the tank. It can be extremely stressful (and fatal) treating the unknown

I know a lot of people on this site swear by the pea trick....maybe after your guy has fasted you could try it again? When my betta was bloated, he refused absolutely everything at first.
I don't have any experience with the Metroplex, wish I could help there. I've had great experience with Seachem products though - unlike some brands, at least I feel like their stuff will actually do something. The Seachem site says that med is for internal parasites and bacterial diseases...are you thinking something like that is going on? It's always hard for me to know when a medicine is actually needed and when to just let things like clean water/time do their magic...Hopefully someone with more betta experience will jump in with more advice. Hope he feels better!
I noticed my Betta’s tummy has been looking a little bigger. Not a lot, but just a little bit. I feed him only twice a day, but he looks a little off. I’ve attached some pictures..it’s hard to get good ones while he’s swimming around Does it look like he’s constipated? I know I post so many questions on here, but I want to be a good mommy!I just purchased some freeze dried Daphnia on Amazon! How much are you supposed to feed them?Daphnia food is supposed to help clear out their gut as well... I couldn't find it at the local fish store, so I ordered it on Amazon. I lost a molly to SBD, tried feeding peas, but it didn't really like them. I'll periodically feed all my fish daphnia as a preventative now.
Great! Thank you!I've read that it's 'light' food and goes through them easy so somebody said they don't worry about overfeeding it.. I'd say a 'heafty' amount compared to regular feeding.
Have you tried fasting her for a day or two?
Edit: Oops, read to fast and I see that you've tried that. Perhaps fasting then a pea?
Thanks so much for the advice, I'll try that. I've just been doing the usual 25% water changes since I didn't want to agitate her too much when she's already not feeling her best, and when she'll go for it I try feeding her the daphnia. I'll try a 3 day fast and then a pea then. Fingers crossed!Not that I like starving fish, but I've gone up to 6 days when we've been away from home. I'd suggest fasting her for 2 or 3, then offering the pea.
Are you keeping the tank extra clean and offering her quality food otherwise?
Wish I could be more help... grasping at straws here. Wishing you luck!
I fear that as well but don't know how to be sure. Hoping some tlc will help.Dropsy?

How did you feed the pea? It must be boiled, de-shelled, and mashed very well.
If that doesn't work, then fast him, and do daily Epsom salt baths twice a day, that'll release the bloat.
It's worked for every single bloated fish I have had.
Thank you for the quick response! I defrosted a frozen pea, soaked it in hot water, de-shelled, mashed it up, and dropped a few bite sized pieces in there that he ate right up. Does the pea HAVE to be boiled? That part I didn’t do
For the Epsom salt baths - could you tell me how you do those please?
Don’t feed him at all, bettas can go weeks without food so a few days won’t hurt him. To do epsom salt baths, take some aquarium water out into a separate container and measure in the correct amount of salt (you can google it, there’s lots of sources. It’ll have all the instructions you need)
Thank you! He hasn’t had his normal pellets in a week now. He’s had 2 days of peas that didn’t work, and I tried daphnia and he wouldn’t eat it. I’ve also done 2 Epsom salt baths. Those haven’t worked either. I really don’t know what to do at this point
Ok, does he look any better? If not, it’s time to start looking at other possibilities. (This is a bit gross) How are is poops? Is he pooping at all? Do they look normal?
It’s the part where is shows a bit of a lighter color than his scales.
It’s not so much that he’s looks constipated it just that he hasn’t pooped in some time. I’ve tried feeding him the betta pellets but he doesn’t seem to like them. So I’ve been giving him the flakes. And every so often I give him a freeze fired blood worm.
