For anyone who owns any noctournal fish such as Striped Raphael Catfish or Kuhli loaches, check out moonlights. I just picked up a simple $14 single submersible white LED (overpriced but far less than the supposed high tec crap you'll pay for at the big online stores), and for once I'm enjoying both ends of the spectrum when it comes to fish habits day or night.
I think it was designed to light very small tanks but in this 30g tall it more or less simulates moonlight which lights things just enough to get the nightowls running but allows the other fish to 'sleep'.
I'm seeing my kuhli's do things I haven't seen in months.
