Two Panda Corydora.......

[Spike89]

I have two panda Corydora that have not stopped playing in the bubbles for a few days now. When the lights go out they calm. The stop for nibbles but then back to racing up and down the bubbles. Is this a bad thing?

By bubbles you mean the bubbles from a bubble wand, or from a powerhead with a venturi attachment? Some Corydoras love to "play" where the water output is directed. This is normal at times but if the fish do it excessively and seem to attempt to try and leap out of the tank, then you might want to check the water parameters. Healthy Corydoras will spend most of their time on the bottom, milling and rooting about for food. The only time you see them get into a frenzy is during feeding time and spawning.

They play in the wand bubbles. They are really young.

My leopard danio are another issue.

I think its alright. Better active than not moving (which means that they could be sick / stressed)

I think it should be normal is your water parameters are ok. Mine love to play on my air stone plate, its like they are having an air bubble shower.
