Ok so I'm starting a new project in hope to breed my 2 onyx clowns. I have a 12 gallon nano cube with 2 clowns I've had for about a year in various tanks. they haven't fully paired yet because there both around the same size, but I'm hoping one I set my lights up to summer lighting they will begin breeding. My lfs told me he would sell me a 120 w metal highlide compact for a 12" nano cube do you guys think this is to much light or any other ideas on light? Any feedback is appreciated.
