I was wondering if anyone had any suggestions for a lighting setup that I could use for my tank that would allow me to see my nocturnal fish but that wouldn't scare it back into hiding? It wouldn't keep kept on all night, just for about ten-twenty minute intervals for me to be able to watch it move around a bit. I was thinking either a red or blue bulb might work? Or perhaps even a blacklight? Any and all thoughts are greatly appreciated!
