Alright guys so I have to RTC×TSN and they look very different from one another I prefer the look of the larger one more than the other but what git me thinking is the larger one resembles a TSN more than a RTC not only is it lighter in color than the other but the big difference is the head shape the larger one has a flater and shorter head while the smaller hybrid has a curve to the top of its head from the eyes to its lips I'm thinking that for the larger one the mom might have been a TSN and the father was the RTC and the opposite for the other hybrid just my theory but its the only explanation I came come up with for such a different looking fish made of the same species what do you guys think

Yeah, different admixture of DNA between them. It's possible one or both could be introgressed back into a parent lineage.

Moved to catfish
 
All goes back to who was mum and who was dad.
From memory the mum gives the look of the fish (but Victor will correct me if I am wrong).
If it looks more redtail, mum was red tail and dad was tsn hence a rtcxtsn cross. If it looks more shovelnose, mum was tsn and dad was rtc, hence tsnxrtc cross.
 
It's also possible that they had the same parents but just ended up with slightly different genetics from one another. Just because they have the same parents doesn't mean they will look the same. I've experienced this with my flowerhorns when I bred the parents of the 2 I currently have. 1 ended up looking like her father while the other sister ended up looking like neither parent.

Didn't think of that good point I just wish I could find more that look like my bigger one that's the look I prefer

Personally I like the smaller one more just because of the clear cut division between the colors and pattern it inherited. I do agree with ya tho that the larger of the 2 does have a nicer looking body and facial appearance. Granted tho I do consider ya lucky because I have seen others of this cross that don't look nice at all. Seen allot of em for sale with bent spines, whiskers or even majorly deformed faces to the point they almost looks like a hybrid between a catfish and a duck.
 
AFAIK, there is no such thing as RTCxTSN hybrid (mother is listed first). If there ever was, it must not have been found viable in a laboratory. We only know TSNxRTC hybrid (mommy = P. fasciatum, likely; daddy = RTC). Hence they all look closer to the TSN.

The difference in color is likely the age / size. The bigger your dark one will get, the lighter it will become.

The difference in the head shape has to do with the very prevalent and common deformity in these hybrids called camel face, duckbill, etc. where the head slopes down more or less strong as opposed to the TSN straight snout. Your bigger one doesn't have it but in fact might have the unnatural curvature in the other direction.

These manmade frankensteins abound in defects.

so how do you explain a liger and a tigon there both different hybrids of the same animal but the liger grows bigger and A liger is the offspring of a male lion and a female tiger.The tigon grows to the average size of a big cat and A tigon is the offspring of a male tiger and a female lion.
 
I may be wrong or don't know something.

This guys knows necrocanis necrocanis
