    Hey all,

    I've noticed that my ottocat' s gills look extremely red. But some also have slight redness

    My parameters are 0/0/5(or 10) if water change is needed.


    Is this ammonia burn? Or heater burn?

    Thanks

    Something like that happened with my Pygmy cories. I'm not sure if you have gravel but when they're sifting in the substrate if it's hard and scratchy like gravel it could hurt their mouths and the bottom of them. If you don't have sand you could switch to it.

    I have gravel but it's all smooth. There aren't any jagged edges. It could still be the gravel?

    I had perfectly smooth gravel and it happened to my cories. It sucked and I eventually change my gravel.

    I think that the larger pieces can damage their undersides.
