I have a 20 long with three alpine newts and about 12 White Cloud Mountain minnows. There are plenty of plants, and the surface is covered in duckweed and dwarf lettuce.
It currently runs with a sponge filter, but I was thinking of removing it and running the tank completely off of plants and water changes.
What do you think? Will it be safe for the creatures? Thanks.
