How to spot early signs of Betta illness

Post by flavorite »

Noticed my betta acting weird lately, like he's not as active and kinda just chills at the bottom. Water params are good, 0 ammonia, 0 nitrite, 10 nitrate. Tank's a 5 gallon with a sponge filter, heated to 78. Anyone got tips on what to look for?

Early signs can be subtle. Look for clamped fins, loss of appetite, or erratic swimming. Check for white spots (ich) or fuzzy patches (fungus). Also, monitor if they're gasping at the surface, which could indicate low oxygen or gill issues. How often do you do water changes?

My guy did the same thing last month. Turned out he had fin rot. Started with just being lazy, then his fins looked ragged. I upped the water changes to twice a week and added almond leaves. He bounced back quick.

Could be stress from something recent. Did you add new decor or tankmates? Even a small change can mess with them.

Agree with coralbay on the clamped fins. Also, watch for color fading or darkening. If they're not eating, try offering live food like brine shrimp to tempt them. Sometimes it's just a phase, but better safe than sorry.

Yo, my betta was straight up ghosting me when he got sick. No energy, no eats, just vibin' at the bottom. Turned out he had internal parasites. Meds fixed him up, but you gotta catch it early. Look for white stringy poop, that's a dead giveaway.

Had a similar scare last week. My dude was hiding more than usual and his colors looked dull. Did a 50% water change and added stress coat. Next day he was back to his feisty self. Sometimes it's just the water, even if params seem fine.

Spot on advice. I'd add that sometimes they just need a break. Bettas can be drama queens, but it's always worth double-checking.

If they're lethargic and params are good, consider temp fluctuations. Even a degree or two can stress them out. Also, check the filter flow isn't too strong. Bettas hate strong currents, might just be tired from fighting it.

Yep, seconding the flow thing. My guy was struggling till I baffled the filter with a sponge. Now he's chill as can be. Also, make sure they've got plenty of resting spots near the surface. They like to lounge.
