Monster Macrobrachium

I recently came across this video of the single most impressive live M. rosenbergii I've ever seen. From the tip of the chela to the end of the uropods, it has to be pushing 24". Has anyone here been able to raise a major male to such enormity? I know this species is aquacultured as a food source in many countries, which leads me to wonder if the countless generations of inbreeding prohibit the commercially available individuals from reaching such gargantuan sizes. I believe it is safe to assume the specimen in the video is from wild blood lines.

As I mentioned before, this is the most impressive live rosenbergii I have seen. This dead specimen just may take home the trophy...

Does no one else find these creatures bad @$$?!

While undoubtedly delicious, I think it'd be awesome as a specimen in a 120 "stout". These things are savage aggressive! Would make for one heck of a spineless wet pet!
