Temp drop affected Discus

[Pinkrblu]

I have a discus, four cardinal tetras and a clown loach in a 29 planted aquarium. I always keep the temp at about 81F. This am when I fed, the discus was behaving very oddly. I checked the temp and it had dropped to 74. I checked and replaced the heater immediately (I always keep spare heaters when I have fish that really demand warmer temps) and started bringing the temp back up slowly over the course of the day. It is now back to normal, but the discus is acting lethargic and resting on the bottom. The other fish are fine, parameters are all fine, but the discus just isn't looking too good. Here's hoping that it is all okay in the morning when I turn lights back on.

81 is on the low side for the Discus. If they are still lethargic this morning pump the temps to or above 85. My tanks are at around 88. This does 2 things. My Discus love the warmer temps and it helps prevent the diseases and fungi the Discus are prone to get.

Good luck....

I've got it up to 84 now, she was doing better this morning. I'll keep raising the temp. Thanks!
