Behavior of my Corydoras in new tank - Happy or stressed? 🤔

[Karen B.]

Greetings 

I transfer my community tank from a 20h to a 30 gallons. 12 more inches of swimming space!

I think my corydoras are playing/having fun. My parameters are ok, except there is no mitrates yet (but no ammonia or nitrite either).

I would just like to make sure I am not mistaken by their behavior. Happy or stressed?

Looks like a whole lotta joy to me!

Looks like they're having a Cory party! Sometimes when Cories are moved to different different tanks they tend to explore the set up like that. I recently put a 6 Cory cats in a QT tank that was cycled & had perfect parameters and they displayed this behavior. Love the scape btw!

looks like they are all nice and healthy, if they where stressed i feel they would be trying to get out the tank or be jumping more than swimming around at the speed of light, so id say there isnt much to worry about here.

Looks normal to me! Mine do this in certain currents and during certain times of the day. Probably a current change in your new tank and they are playing in it. Catfish like current.

It looks like breeding behavior to me in some capacity. There's a video in my journal I'll add of mine.  I see the same behavior coming from yours.  Essentially, big water change, they are following the female around a bit.

Those are happy cory.  When they start to quickly cross in the T shape it’s the start of mating behavior. Congratulations

Unhappy Cory behavior is constantly going to the surface to gulp water, swimming up at the surface, or laying lethargically, hiding or gulping. Although, sometimes Cories will sometimes "play dead" and lay sideways or even upside-down, it's usually for a short period of time, of just while they are napping or resting.
