Gravel help.

I’ve been letting a 20 gallon cycle for just short of a week now, and I was wanting to get some Cory catfish or a couple loaches for it, but I’ve learned that certain gravel types aren’t good for them.

This is specifically the gravel I used, and wanted some opinions on whether or not it would be good to use with those fish. Thank you all for the help.
