I have 5 of these in my planted 75 gallon tank and almost never see them. The only time they come out is when I feed them and even then they don't stay out for long. I know they prefer to graze at night but my peppered corys in the 29 gallon aren't like that. At times I have even worried that some have died and I just dont know it but I have confirmed as recently as last weekend that they are all in there. To do that, I feed after the lights go out, turn off all the lights in the house so it is totally dark and stand there with a flash light until I can see them all out at once. Sometimes that takes 30 minutes or more. Anyway, I was just wondering if everyone elses were as shy as mine. They are very pretty and I would like to see them out more. My wife kids me that they're just an urban legend and don't really exist.
