signs of stress in Betta fish

Post by oceanix4 »

I've noticed my betta acting weird lately, like clamping his fins and hiding more than usual. Water params are good, 0 ammonia, 0 nitrite, 5 nitrate. Tank is 5 gallons, heated to 78, filtered with a sponge. Anyone know what else could be stressing him out?

Maybe check the lighting. Too bright or too long can stress them. Mine did better when I cut the light to 6 hours.

Yo, my dude was the same till I moved his tank away from the window. Sunlight was messing with his vibe, now he's chill.

Lighting is huge. Also, any recent tank changes? New decor or tankmates can freak them out.

Clamped fins are a classic stress sign. How often do you do water changes? Even with good params, buildup can irritate them.

Mine hated the filter flow. Had to baffle it with a sponge. Now he's way happier, no more hiding.

Could be boredom. Try adding some live plants or floating logs. Mine perks up when I switch things around a bit.

Y'all forgetting about temp swings. Heater working right? My guy was sketchy till I got a new one.

Temperature stability is crucial. Also, check for drafts near the tank. Even small changes can stress them.
