I'm not sure if it's really a concern. My understanding is that fronies are deep water African lake cichlids, so aren't substrate dwellers. Now in the home aquarium this is different. What ever option you go for, you want one that doesn't allow waste (uneaten food and excrement) to filter down through the substrate, but rather sit on top. This way it's either propelled towards a filter/sump intake or easily vacuumed up during a water change.
