I just was watching my tank, and realized that I could only find 4 of my 6 cories. I finally found one imitating a piece of gravel. I don't know why he's so quiet. But the other one took me even longer, he was stuck in a corner, wedged between the glass and some air tubing. I don't know how long he was stuck.
Obviously he's stressed, and now just laying on the bottom of the tank. But is there anything special I should do for him? I know they need to gulp air- is he going to be in trouble because he couldn't do that?
How important is the air gulping, anyways? The two littlest (and of course, the one who was stuck was one of the tinies!) seem like they have trouble getting all the way to the top of the water to gulp air. These are habrosus cories in a 20g tall tank. They will start from the bottom of the tank, swim as high as they can, but they always seem to stop just a half inch short of the top of the water, then dive all the way back down, and try again. Of course, maybe that's just them being goofy cories... Its just that I only see the tiny ones doing that.
