Okay, I know you guys are tired of these types of threads, but I don't really know what to put in my 10 gallon aquarium. It's fully cycled (for years now) and is planted. Currently I have 1 male betta and 3 leopard cories and 1 skunk cory. I have one ten gallon filter on it now and will add another filter, maybe an aquaclear mini or up to 200. I might want to put in a group of small schooling fish (4 neon tetras) or 3 harlequins. But that might be overstocking. Is that okay? Or my other idea is to get a smallish peaceful fish that doesn't need to be in groups. Any suggestions? Thanks.
