Alright. So, is there an actual thing as a red tail cat crossed with a TIGER shovelnose? Because mine and everyone else's has SPOTS not stripes... So what type of shovelnose is the common "hybrid catfish" mixed with?

RTC (dad) x Pseudoplatystoma fasciatum (mom)

Are you asking why the genes blended together as they did? AFAIU, it's a miracle in itself they blended and provided a viable offspring.

IDK. It's a highly scientific question. Genes determine everything, including the looks.

Its just that I had read somewhere that they were crossed with a "spotted shovelnose" and I can not find any fish commonly referred to as spotted shovelnose...

Spotted TSN is corruscans. It is not the one used to produce this hybrid. According to Necro's trustworthy info anyway. Can you link the source of your info or show where it came from?

Spotted Sorubim - http://www.fishing-worldrecords.com/scientificname/Pseudoplatystoma corruscans/show - Sorubim is another name for Shovelnose, as in the Sorubim genus - S. lima, elongatus, trigocephalus, etc.

I forget... Somebody just pointed out that hybrids have spots unlike TSN that has stripes...

^ you also have to account for some RTCs having spots, it may not come from the TSN side at all

RTCs have spots on their cranial, not the body.

It is unreasonable to expect any hybrid to display all the features of both parents combined.

-- For instance, the hybrid does not have the famous striking white lateral stripe of the RTC but has a dark top and a light bottom like in a TSN.

-- The fin sizes and body proportions are mostly midway between the two but a bit closer to the TSN.

-- The hybrid has little of the red in the finnage as do RTCs.

-- The temperament and behavior also appears as if a mean arithmetic between the parents.

-- It appears the incorporation of the RTC paternal genes disrupted the base colors and the stripe pattern of the fasciatum mother.

FF, you are right in your inkling that the hybrid looks overall closer to the maternal species, the TSN, which is fathomable, but it does not mean at all that it can be expected to have or should have the stripes.

I'd think that's all laymen like us could say here, more or less.

If anyone else provided more insight and/or showed me wrong, that be wonderful.
 
Variation in individuals may produce some hybrids showing some of the characteristics you said they didn't, especially w/ hybridizing you never really know what'll come out ya know lol I can't prove it, but if natural occurring specie have such variation then man made ones must also
