Gravel Substrate

[homerhotspur]

My tank has a gravel substrate ( mixed gems type). Would this be considered as too ' sharp' for Corys?

If so, I have seen a previous answer suggesting tupperware(or similar) containers making a ' sandpit' which seems the easiest option.

From what i have researched on here sand is the best substrate for Cory's as they have sensitive and delicate barbules(sp?) that can be damaged by gravel

gravel is ok as long as it doesnt have sharp edges so rounded basically
