Interesting question.....

I've seen 30"+ specimens TL & i'd expect them to go bigger - if you have got the correct environment for them, but i cannot say for definate

well seeing its a hybrid, won't it very considerably based on what genetics it gets?

Well Iam thinking the largeat it could grow anywhere from 32" to 43" in SL.
But Iam also thinking about the possibilty of them getting bigger than 43"SL.
Iam also thinking that they stablize in size somewhere inbetween 32" and 43" SL.

Hybrids often have vigorous growth, so in a planning situation I would check the potential size for the two species involved (if known) then plan for the larger of the two.

No reason why it wouldn't be 60"+. They don't tend to be kept by folks that give them enough room and there is a misconception that for some reason because they're hybrids that they will somehow be better able to survive being stunted. Best advice is above, plan for the size of the largest species in the mix.

Or even a bit larger: Ligers and Tiglons (Lion x Tiger hybrids) are often quite a bit larger than the two parent species. But yes, count on it being AT LEAST as big as the parent species - which is substantial size...

While Ligers get larger than both parents, Tiglons actually do not get larger than their parent species.

Cat-eLog states max size for an RTC is 43" SL, or 3' 7". Mr. Ray Lucas from Buffalo NY, I am told a known fish expert, told me in a private conversation that he saw 7'-8' RTCs (I presume TL) at the local SA fish markets for sale. This makes Jools' remark more understandable to me. (He says he's been to your house a couple of times, Jools.)

He also said he saw live Oxydoras Nigers of 7' in some guy's tank/pond.

Well, let me just say that although I had the pleasure of Ray's company in Edinburgh for a day, he didn't get to my house. So, a bit of an exaggeration there. That said, I think 42" (106.7cm) SL might be 10 or 20 cms to short given the ones I've seen local fishermen make a fuss about in South America. Might be worth a review of the catelog data.

Also, for clarity, my 60"+ comment was TL. I was following suit in terms of the previous posts.

Jools, it is most likely my faulty memory. Pls, do not blame Ray for my free paraphrasing of his words.
