breeding RTC with smaller Pimelodidae species?

[Columbian Shark 3]

I know there is a RTCxParoon(P.Sanitwongsai) hybrid although I've only seen a juvi from someone here who had a thread or post of it.
So maybe a cross with P.myanmar 23cm; P.mahakamensis 18.2cm; P.macronema 30cm? But I'm not a geneticist, just throwing around wild ideas.

Heres necrocanis' marblexRTC :http://www.monsterfishkeepers.com/forums/showthread.php?61968-hybrid-catfish/page13

Also according to necro he has kept a tsn x p. blochii hybrid, and I think the Pimelodus blochi is much smaller than RTC.

Yep Blochiis only get to 10-12". Big fish but NOTHING compared to RTCs.

Though slightly smaller, here's a cross between RTC and P. niger:

are you trying to cross breed lion and a cat?

impossible, get a bigger tank

anything is possible just about tank space money and quite a few other factors. impossible is tryin to get someone to pay for a pacu

Possibilities are endless. I would suggest stripping eggs from a RTC and milking sperm from a smaller cat, but vice versa may have better results. Trial and error. And just because rtc eggs and whatever sperm doesnt work, do try the vice versa. simply switching those factors could drastically change your success rate. Have fun trying to strip a rtc though, ahahaha
