Nope, who said that?

I guess you'd be more experienced than I am in the aro-keeping world. Isn't it more or less true aros from different farms have their own characteristics?

Hasn't the RTGxXB bubble been burst already?

so, u agreed that xbreeding btw XB and RTG might occurs lar....its just that it dun makes sense to farms owners only...

Agree with the second paragraph but it doesn't shed light on the threadstarter's topic. So are we trying to try to conclude if HBRTGs are pure strains or whether the HBRTGs are in fact RTGxXB descendants?

Imo nope, no 2 batches have exactly the same characteristics ....some might look simillar but they might not be genetically simillar.

I myself am in the camp of belivers that HBRTGs are juz selected and improved RTGs rather then the theory of crossing them with XBs ...
However for the theory of crossbreeding Xb with RTG resulting in HBRTG, the fish allele has to result in a mixture whereby AB co-dominant which the thread starter has mention isnt possible in the first few generations an may take many years which isnt commercially viable

Never said any 2 batches can have exactly the same characteristics leh. Just that a larger percentage of them show traits that are seldom/not seen in another supposedly same-strain fish from another farm.

Like I had said in a previous post, what if XBs are not in the equation? What if SRs can be used to get the HBRTG effect? And what if RTGx(banjarXRTG) can produce a similar fish? Not suggesting anything, have no evidence to prove or what. Just a speculation.

agree... so if the farm owner say no no, then we will all no no.

oh ok,paiseh misread , but then again, none of us has seen every single aro from a certain farm, its very hard to conclude that most of them show that traits, i belive all of us only seen a small portion of all the aros produced by a farm (some are exported overseas and so on...not to mention the aros we have locally are juz a fraction of the amount a farm produces). Some LFS get to select their aros from the farm too, so they might have pick out those aros with the traits they like (eg yellowish tails) and sell at their shop?

juz my 0.2 cents

precisely .... so how do we conclude all of them carry a simillar traits?

Hi John,

I have seen first generation of a cross breed that looks like a combination of both parents. For example, I used to have a Red Gold Hybrid that has a full red single tone tail (just like a red) and a cross back coloration on the body. This piece father is a cross back and mother is a red.
