    Cory Catfish swim really fast to the top normal?

    I have a Emerald Cory and I notice sometimes he just swim really fast to the top and go straight back down. Is that normal? Sometimes he look like he is dead since he doesn't move for a long time an then he suddenly does that. Very weird fish.

    totally normal behavior for corys from what I've seen in my fish as well as research, I find it rather endearing.

    Definitely normal behavior. I find the emeralds and the albinos are kinda lazy. My sterbai are all over the place!!

    For other fish yes, but corys continue the behavior in well oxygenated water (if my tank is low o2 then there is a secret society of oxygen sucking gremlins hiding in the silicone).

    If it's active when being fed then it's probably fine.

    wait....A <---- (singular) cory? corys do like to be kept in a group of +6, (rarely a problem as they are fastidious little fish).
