new behavior in panda cories


A couple nights ago I rearranged the wood in my tank a bit in the process of cleaning, and also installed a canister filter in addition to the AquaClear HOB that was already there.

Ever since then, my panda cories have decided that the top of the heater (a Fluval E), only about an inch below the surface, is a great place to hang out, singly or in pairs.

Anyone seen that happen before? Is it anything to worry about, or are they just being the odd little fish they are?

(I do have an ongoing cycle in my tank, due to treatment of a columnaris infection. I'm using Prime, water changes, and zeolite to help deal with it in the meantime. But they're not gasping, and neither are the other fish, so I don't think it's related.)

Are they all trying to get up there at the same time, or is it just one or two? If it's just one or two and they don't seem to care if they're off, it's probably just cories being strange. Cories are really weird fish sometimes, for no real reason.

It's just one or two. Yeah, I think it's just weirdness.

My cories won't stop sprinting up and down the glass all day and night. It's actually quite annoying and stressful, I wish they would stop... I may get some more and see if that changes their behavior.

I think this is a sign of nervousness or stress or excitement or something. The fact that they do it 24-7 is not good I don't think

That is quite curious. Do they fish seem to be exhibiting repiratory distress/have redness around their gills?

No, nothing visible -- however, I lost one Friday night and one last night, and I'm down to 2 left out of the original 8.

I suspect these pandas were an unhealthy group. They brought columnaris with them into my tank, and though I only lost two before treatment seemed to clear it up, they may have been repeatedly stressed by disease.

All my other fish (including 8 gold laser cories) have been fine, through the columnaris and the mini-cycle caused by the treatment I used.

Hmm, I see that so often in stores with some types of cories -- particuarly bronze, albinos and pandas -- that I took it as a normal sign of healthy behavior. But if it actually is a stress indicator, that would make sense. (My gold lasers have always been pretty placid, except for darting when scared and getting excited about food.)

IMO & IME that is a sign of happiness in many cories. I own 6 albino, 4 green, 4 panda, 3 julii, and 4 sterbai cories. They all are very active and when they aren't that's when it has been an indicator for me to check them out because something isn't right (either sick or water parameters).
BTW...if the sprinting is bothersome...wait till they spawn...super duper active.....

Mine did that until I increased their numbers. Then they calmed down. I believe two is too few.
