everyone moved but two...cory behavior

[Meredith]

So everyone is back in the big tank except the two rasboras. I want to move them badly but I am also very scared to put them in there. I don't know if they are still sick or what. I am delighted with my angel fish. Its very active, always hungry, a joy to watch. My concern now is for one of my corys. A majority of its time is spent swimming back and forth along the front of the tank. Not a leisure swim, he looks like he is swimming as hard as he can. Sometimes he will swim a little up, a little down at one end of the tank but then he is back and forth, again and again. Does anyone elses do this? He is eating fine (when he stops to eat), no sign of illness, just checked the params last night , no ammo, no nitrites, nitrates 20. Could it be boredom? Its very strange.

My cories do this alot too, and nothing is wrong with them. When you are close to the glass, or just around, they get all excited.

Try observing from a far every once in a while and see if this wild cory as calmed a bit.

HTH

hehe! isn't that sweet!

That's the case with mine!

Try doing what I said, and watching them from another room or around the corner if you can, and let us know if this is the case.

My corys do that all the time.
Corys often swim up to the surface and take a gulp of air - they can absorb oxygen through the gut wall.
And then, they fart! 8O
It's true, I've seen it many times!

Watch your corys closely for awhile, and you will see them dart up to the surface and then go to the bottom to rest. After a few minutes, you'll see tiny bubbles come out of them. They have no shame!

And then, they fart!

So that's what that is?!

 

[Meredith]

Well the cory seems fine now, I think it is just excitement. I have noticed the "farting" Very funny!

 

[Fishalicious]

I think alot of different fish do this when excited.
My Danios, Oto's AND rainbowfish do it.
The rainbows and two of the danios do it when
I enter the room. Maybe they're telling me they're
hungry
