How many tads can you put in each container? Also, are there any limitations/issues you have come accross with adding different age tads in the containers?Ben E said:All tads are set up with a clay/soil bottom with leaf litter a few rocks and floating plants. Water is never changed. Tadpoles actively ingest the substrate and are fed supplementally about twice weekly. This is low maintenance. Currently using this method with 7 genera.
