My Intermedius haven't bred yet, so I can't comment from experience, but the person I bought them from said that they often lay larger clutches and are as diligent about feeding the tads as pumilio are. Also, unlike pumilios, you can rear healthy tads with dried foods high in protein. For serious breeders, it is my understanding that the success rate and yield are both higher when the eggs are pulled. A pair won't lay another clutch if it is caring for tads.

But, don't take my word on the subject since I'm relatively new to thumbnails. There are many thumbnails specialists who know a whole lot more than I do.

Good luck.
