Mine was active before I switched from gravel to sand.
They do prefer the sand though, and it is much cheaper than gravel.
A 50lb bag of sand at HomoDepot is about 3 bucks.
Mine swim to the top to steal food, even though I feed them shrimp pellets, catfish discs and frozen foods.
My parameters are very stable to water changes are not something I do often.
But yeah, I agree, we do need more info.
My guess is that they need more buddies, or need morecover. My tank has live plants and rocks. they dig lil caves under the rocks and hang out there or they chill on leaves of plants.
I have had corys before, but these are the only ones who come to the surface to feed. They are really fat so I guess these are some serious pigs.
Yes, mine do that as well. I tested the water, all good there.
corydora like small fine substrate, plenty of cover and lots of frineds, i try to keep them in groups of at least 6, when theres not enough they tend to hide/laze aroundalot but the more you have themore comortable they feel in their environment. i love watching mine dart around the tank, but i find if i dont have enough i dont see them, right now i have 10 and there veyr active.
Have you tried combining different species of cory ?
i have a mixed group right now of agassizi, false julii and greens, they all seem to be quite happy as a group though the greens are bigger than my spotty cories i prefer the spots, would love to add some pandas and peppereds at some point
Ive found in terms of relitive bio-load they tend to be "light" on the load so i generally feel safe adding a few more than woudl otherwise be permitted based on gallonage (assuming your ontop of your waterchanges and testing.

I have four. They are pretty young, I think, as they are still fairly active but they do have their moments when they just sit there, doing nothing.
Do you have sand substrate? If not, get some, that is the best for corys. They're pretty easy fish and while I've heard from many that theirs will hide when someone approaches the tank, mine have not done that yet.
Oh and I agree with providing cover. I have some rock decorations, the obligatory castle, (that will eventually be phased out), driftwood, (for the pleco), and live plants. There is a lot for them to do and explore in that tank.
They also have tank mates:
1 pleco
3 baby panda platys, (I sold the rest because holy cow they breed like rabbits)
4 danio
4 flying foxes
Corys are schooling fish. However, it is best to keep them in groups of 6 or more of their own species. They will be more active and display much more natural behavior. You can, however, mix albinos and emeralds, as the albinos are just a human-bred form of the emerald. But you shouldn't mix, say, emeralds and peppered cories unless you have enough room for 6 of each.
I have a 20 gallon tank with 2 albinos, 2 emeralds, 1 peppered, and 1 panda. The mixed group was a result of a family member threatening to flush them because she wanted to close her tank, so I took them all. If I had my choice I would not have this mixed lot and would instead have all pandas. Mine do stick close to one another, but that isn't the same behavior as schooling.
And yes, they do need sand. They filter the sand through their gills for food. Hard gravel can hurt their barbels (whiskers) and cause infection. If you can't change substrate, try giving them a bowl of sand in the tank. They're really fun to watch doing their thing.
Be aware also that the species can differ widely in size, which is something to keep in mind depending on your tank size. The emeralds for example are twice as big as the albinos (even thought they are actually at the same species). There are dwarf species that are quite small, and others like the Emeralds that are quite big.
What kind of substrate do you have? Very small gravel or sand is best, or it damages their barbels. What are you feeding them, how often, and how large is the tank? What do you mean by "clean", have you tested the water parameters? How often do you do partial water changes? We just need a little more info.
They would prefer sand or other fine substrate.
I use eco-complete for my plants. It has no sharp edge and it is mostly very fine pieces.
I feed Hikari Algae Wafer. They love it.
They are in my 40 gallon.
Mine adore the wafers too (same brand). If only I could keep the ghost shrimp from stealing them and carrying them off! They are fearless little buggers- they'll get right there with the cory flock and just steal it right out from under them.

Agree on the algae wafers. I drop some in and the corys, the pleco and the flying foxes all go crazy for them. The other fish food goes to the danios and panda platys.
