discus hiding in tank plants

Post by joshito »

My discus have been hiding in the plants all day. Tank's a 75 gallon, temp at 84F, pH 6.8, 0 ammonia, 0 nitrite, 10 nitrate. Got some driftwood and Amazon swords. They usually swim around but been acting sketchy since I added a new canister filter yesterday. Anyone else deal with this?

Yep, discus can get spooked by changes. That new filter might've messed with the flow or noise level. Try turning it down a notch or adding more cover like floating plants. What's their feeding routine like? Sometimes they chill out if you stick to a schedule.

Mine did the same when I swapped lights. Could be the brightness or spectrum if you changed that too. How old are they? Juveniles hide more than adults.

New equipment always stresses them out. Check if the outflow's too strong, discus hate strong currents. Baffle it with a sponge if needed. Also, what's your water change schedule? Dirty water can make them hide.

Thanks for the tips, gonna try reducing the flow and adding more plants. Water changes are 30% twice a week, same as always.

Mine hid for days after I moved their tank. They're drama queens. If params are solid, just give 'em time. What's the substrate? Sand's better for their barbels, keeps 'em comfy.

Agree with bloom. Discus are sensitive to vibes. Tankmates could also be a factor—anything new or aggressive in there? My angelfish used to bully 'em till I rearranged the decor.

For real, they're like aquatic divas. Joshito, what's the lighting cycle? Too much light can freak 'em out. Try dimming it or adding a siesta period.

Also, check for parasites. Hiding's a classic sign of stress from internal issues. When's the last time you dewormed 'em? Metroplex's a good call if they're off food too.

Could be the filter media. Did you rinse it in tap water? Chlorine's a killer. Always use dechlorinated water for rinsing. Also, how's the oxygen level? Low O2 makes 'em lethargic.
