Aquarium Advice Apprentice
today i brought some bronze corydoras and a hillstream loach for my aquarium. the corydoras keep darting up to the top of the tank then swimming back down again. does that mean i have low oxygen levels? my comet and shebunkin seem to be hanging round at the top lots as well. i have 3 plants and some weed floating about in the tank, but is this enough? would an aeration stone be worth buying? i have been told by the pet shop that they aren't totally necessary but i don't know how much knowledge they have really.
