Hate to link to Facebook but can’t get the direct link. Check this guy out.
Only video that was posted. I doubt it’s 20in but probably up there. Probably imported large and grown some.i don't have FB so thanks for sharing this....dang that video is too short. is that the only vid he posted? that looks like a 20 incher huh? this is what i have been saying since before...give the manueli a really big tank and it will patrol the whole tank endlessly and it'll get very aggressive as well. it is probably the most active serrasalmus specie out there given a very huge home.
ah ok...thanks bud! he doesn't seem to have small hands so if he combines both hands that's a good 18 inches then there's probably a good 2-3 inch left to cover the whole fish till the end of the tail so my guesstimate is anywhere from 18-20 inches but heck maybe i'm wrong.Only video that was posted.
