Any problems with breeding pairs where female is larger than male?

[Yellow]

Has anyone tried breeding a pair of anabantoids (specifically, paradise fish, but should be generalisable) where the female is a bit larger than the male? I was thinking that this would prevent the female from being dangerously harassed by the male, but it looks like it's gone to the other extreme and the male spends most of his time hiding. Perhaps there's a threshold size at which everything works out.

I've tried breeding WCMMs where the female was about the size of a female guppy and male was barely mature (but mature enough), which didn't work, oddly enough.

I have always bred white clouds in a breeding group and been successful but I have not bred paradise fish so not sure about them. Many fish will breed successfully in a group if you find a way to separate them from the eggs.
