How to prevent swim bladder issues in Bettas

Post by flairon »

I've noticed my betta floating weirdly lately, kinda sideways. Water params are good, 0 ammonia, 0 nitrite, 10 nitrate. Tank's a 5 gallon with a sponge filter, heated to 78. Feeding pellets twice a day, but maybe I'm overdoing it? Anyone got tips to stop this before it gets worse?

Swim bladder issues often stem from overfeeding or poor diet. Try fasting for a couple days, then switch to smaller, more frequent meals. Soaking pellets before feeding can help too, since dry food expands in their stomach. Also, check if they're constipated—daphnia or brine shrimp can act as a laxative.

Yep, overfeeding's a common culprit. I had the same issue and cutting back to once a day fixed it. Also, make sure the pellets are high quality, not the cheap stuff.

Mine had this issue last month. I fasted him for three days, then fed daphnia. Worked like a charm. Now I feed every other day and mix in frozen foods. His colors even got brighter. Maybe try that and see if it helps?

If fasting doesn't cut it, check the water temp consistency. Fluctuations can mess with their digestion. Also, avoid feeding flakes—they're harder to digest and can cause bloating. Stick to pellets or live foods if you can.

This is solid advice. I'd add that keeping the tank clean is key. Uneaten food decays and spikes ammonia, which stresses them out. A weekly 20% water change can prevent a lot of issues.

Thanks for the advice, everyone. Gonna try fasting first, then switch to smaller meals. Appreciate the help!

Another thing to watch is tank height. Bettas prefer longer tanks over tall ones because they need to surface for air. If yours is struggling to swim up, it might exacerbate the issue. A 5 gallon long would be better than a tall one.

I've heard some folks use epsom salt baths for severe cases. Never tried it myself, but it's supposed to reduce swelling. Just make sure to research the dosage first, too much can be sketchy.

Mine had this and it turned out he was just lazy. Started floating weirdly but was otherwise fine. Sometimes they're just weird like that. Still, better safe than sorry with the fasting tip.
