I'm changing my daughters tank from guppies and endlers. I'm keep 10 neon tetras, 3 albino corys, and 2 albino bristlenose plecos that are currently in the tank. I've been debating on what to add. The tank is decently planted with only about the front 4-6 inches not planted. Substrate is fluorite, I have a 2215 for the filter, and do 50-75% water changes every week to two weeks. I'm leaning toward a pair of gbr, more neons and some harlequin rad boras maybe. Any thoughts or advice?
