I figure this is a good way to get the conversation going.
We currently have one community tank with a dwarf gourami, corydoras, neon tetras, a small colony of cherry shrimp, an assassin snail, and a plague of ramshorn snails that hitched a ride on some water lettuce we bought a few years ago.
I’ve been trying to introduce guppies in my tank, but all my attempts failed. What is the secret? I have a 20G and just 3 glofish tetras, a little bit of duckweed, and that’s all.
