I have a group of 6 rrp. I read that they can breed when they are at least .5 inches long and over. All of my specimens are over this length. Is there anything that I need to do to induce spawing or is it just a matter of waiting?

Any help is greatly appreciated

I've not kept these fish before but I was reading about them. The males are apparently very territorial in the breeding season. I would separate out a male with 1 or more females and see what happens. /shrug sorry I am not more help.

I can't help with any specifics either.  The biggest things to consider (with any species you are trying to breed) is photoperiod, water temperature, and spawning medium.


I know you probably have already read this, but this seemed pretty useful for describing habitat and spawning in the wild.  Now that I have read this, it seems RRP spawn throughout a large chunk of the year in variable temperature.  So in the case, you may just have to do like minorhero said and "see what happens".

I really appreciate the input. For now, like ya'll said, I'll just wait and see if any of them will color up, and then once they do, separate them.
