Decorations for Lemon Tetras
I've just recently started my 20G tank, and it is still cycling. I've got substrate in it and some plastic plants from Walmart. I've got Lemon Tetras (so far).
I'm wondering what types of structures and 'decorations' Lemon Tetras would be happiest with. Caves? Tunnels? Nooks and crannies? Open spaces? High up? Low down? Any info and suggestions would be great!
