Synodontis eupterus strange behavior.

[Syno_Eupterus.]

Lately my syno. euppies have started to hang out on one side of their tank instead of hanging out in their own caves. What gives>?. They are so crowded by choice that they are almost top of each other at times. I thought at first it might be because they saw me watching them and wanted food.
Now it seems they hang on that end of the tank every time I check on them. AND I usually was feeding them on the other end of the tank.

What other fish are in the tank with them?

Species tank, it's just them. Tank looks empty with them all hanging together on one end.

Hmmm....I am not sure right off hand, in this post the same was reported just recently.

I didn't change my syno's gravel.

did you move anything around in their tank? Mine can get really different if I move something to clean and do not get it back exactly right.

Mine stayed upside down hovering all together in the middle for about a whole week. Now they are all over again. i think mine was because the substrate got a little lighter in colour. But who knows?

whats your tank parameters? A NI NA PH temp?

Moved things over to vacuum gravel. It was quite dirty since the faucet attachment style siphon( Lee brand) didn't reach the bottom. I finally got a longer one which is a python brand. Only tank that could really use more filtration around here.

Testing the water would be a really good idea too. Since I have the water testing kits mostly here with me, have to remember to bring them with me next time.
