I recently introduced a pair of bronze corys into my 10gallon tank. It is my understanding that thier whiskers may eventually wear down because my substrate is composed entirely of gravel.
How important/urgent is it for me to replace my gravel or add fine sand for the corys? My gravel is no larger than 1/4 inch in diameter and fairly smooth. Is it practical to have both gravel and sand in the tank?
Thanks in advance.
