Hi,
I have a planted tank with Eco Complete substrate. I've had a Peppered Cory for almost 5 months now and he was a big 2". I put in 2 Oto Cats 2 weeks ago and noticed they would sometimes "climb" or even "suck" on him.
This morning, I could not find my cory. I took out all my plants and combed through the substrate (ended up with bacterial bloom with the huge media disturbance). I checked the filter. I shone a flashlight at all the holes in my drift wood. I have no idea what happened.
My other fish are Microrasbora erythromicron, golden pristellas and zebra danios. So they don't really go near the bottom.
With only the Oto Cats interacting with him, I hate to ask if it's possible they ate him. My tank was clean (was because of the present bacterial bloom) so I would drop in algae wafers. I did not drop in an algae wafer last night though...
The Oto Cats are definitely not
CAE. CAE have scales.
