Are their care the same as other cories? I lost a shoal of emeralds due to a mini cycle

How hard will it be to switch out the substrates?

Given that I know nothing about your tank or what kind of gravel, etc, it's a bit hard to say. I have removed substrate with a wide syphon hose and then added the new substrate in its place. I didn't find it hard, but the bigger the substrate ...

I'm sure it was due to the stress of traveling through the mail. They love/need driftwood. Here's what they look like now: (They look darker without ...

I mixed in some river rocks a few weeks ago since I am getting some cory's and I don't want their barbs to get caught also its just regular white rocks in my tank

You also need to have driftwood in your ...

Or is he going to become darker?

One reason why your fish is so pale is because of the light-colored substrate. The other reason is that it's probably quite uncomfortable in your tank (the coral chips you are using as substrate is making the water far too hard for its liking).

I'd switch the ...
