I would say your fine with he space you have now, but I would also wait for more peoples thoughts. I don't have much experience with Corydoras :/
Thank guys!what size tank? what substrate?
the wood is fine but....cories usually like to be in groups... usually best on a nice sand substrat and they are very active swimmers and like foraging space.
The gravel is not sharp. I tested it by rubbing and squeezing the gravel between my fingers. It didn't scrape or cut me.To your initial question, you're fine. Corys are "substrate" fish, true, but most species (and C. panda do this much more than some others) will spend more time off the substrate, browsing every surface be it plant leaf, wood, or tank walls. But of the several species I have, they seem to remain together most of the time. My group of five have taken a real like to playing in the filter stream periodically; probably not surprising, since this species is native to slightly faster-flowing clear water streams coming down from the Andes.
That tank looks very nice Patricia.:cheers:
I agree with Ed on sand, but if the gravel is not rough you should have no issues. Corys do like to sift sand through their mouths, ejecting it via the gills, which they obviously can't do with gravel. But though I have now changed to sand, I had corys thrive over natural gravel for many years. I mentioned their habitat above; those streams have substrates of sand and/or fine gravel. Just so long as the gravel is not rough, you're OK.

1. You think I should remove the big driftwood in the middle?1) I always try and get more open "Floor space" for corys, but....
2) for only 4 Pandas that looks OK, but........
3) corys like to be in big schools, 6-8 would be better.
PS--What is that "White disk" between the drift woods??
It is very easy to clean. It is small grained but it is heavy that it does not get suck up when I vacuum the gravel.6 corys are fine in your tank. I agree with Byron, it looks very good. I've thought of trying Peace River, I love the color & small rounded grains, more of a fine gravel. It seems like it would be easy clean, is it?
I would not remove wood. If anything, add more. This is important for soft water fish including corys.You think I should remove the big driftwood in the middle?
I wouldn't, given the fish species. Presumably the fish are going straight in this display tank.My order of fish is coming tomorrow. Do I need to do a partial water change, even though I did my weekly water change on this past Friday (I removed about 50% of the water while I gravel vac)?
Thanks I will leave it as is, for nowI would not remove wood. If anything, add more. This is important for soft water fish including corys.
