I have a few nocturnal fish like the eel and eel-tail cat that hunt when I turn the light off. Last time I did I lost a few neons and a white cloud or two. I have no probs with algae and I've been doing this for almost a year now. Visually there are no probs with my tank, all my fish are healthy and my plants flourish, also, I don't clean my tank at all except for the magnet glass cleaner on occasions, is this normal I don't really now anyone else with fish and my LPS
is pathetic, I order my fish privately.
