***breeing double reds***

I've heard of this too, and I have used them on my dwarf tanks, though not with any particular expectations. If you like the effect, use them. I've actually found one as a lone spot light to be insufficient to provide enough light to help mom protect her fry when predators are present. With multiple lights, I expect they would serve fine. I've seen no noticeable difference in breeding or behavior while using them. As far as I'm concerned, it's probably bunk; most likely propogated by the manufacturers or sellers.

Fact is, you don't need them for cacatuoides anyway. They'll do what comes naturally without the use of special conditioning lights. Just feed them well. As a word of warning though, a 10 is on the small side. I do it, but it's not ideal and I do have to watch aggression more closely, and fry should be removed for growout at an earlier time.
