I’m currently battling a planaria problem which may have been caused by overfeeding and not vacuuming the gravel properly. I’ve recently added a feeding dish for the amanos to make cleanup easier and was wondering if I can do the same for Corydoras? I also have aquasoil substrate so I was thinking maybe adding sand to the Corydoras’ feeding dish and perhaps lessen the chances of the amanos stealing their food. Will that work? Has anyone tried this before?
