Why does my cory swim up and down the side of the tank?

[umitosora]

I have added 6 Julii cory fish in my tank yesterday.

The fish swim up and down the side of the tank all day long! Non Stop! (They also like to do this in the bubble curtain.)

Now Cardinal tetras are copying and doing the same thing occasionally.

Should I be worried? Are they stressing out other fish?

I have 34 gallon tall tank.

Fish I have in there are: 1 Dwarf Gourami, 6 cardinal tetras and 6 Julii cories. DG plays in the same manner in the bubbles too. He has been doing this before I got cory) They are all juveniles.

Ammonia:0
Nitrite: 0

Most likely getting used to the tank. My Y. sidthimunki have been doing it all week since I first got them. A few of them have started to branch out to other areas of my tank now. I wouldn't worry.

My cories have been doing that for a year... Definitely nothing to worry about.

Cories is crazy. They do some weird stuff.

Mine do the same thing. They're especially fond of playing in the bubbles.

No worries.


Cories like the surf.

I've had my cories forever and they still do it. They also play in the bubble wall sometimes, I think it's cute! They are just silly little critters :silly:

They are exploring

Yea definitely nothing to worry about.

My cories did it the first week I had them too. They've stopped doing it for the most part.

I see them do it occasionally now.
