Hey guys! Im just really curious about the so called 'blue base'. I know blue is the preferred color of other bases like there is also green and purple base on some aro's. Do a lot of rtgs have blue base? Is blue base the most common base for rtgs? Or do only the extremely pricy rtgs get blue base??

Thanks
 
most blue based aro's are crossbacks or otherwise known as xbacks.
 
Yes there are xbacks that have blue base and there are RTG's with blue base as well. So really my question is " is it common for most RTG's to have blue base? Or is it rare ? and only the expensive rtgs have blue base cause it's rare for rtgs to have blue base"
 
Blue Base is more common in Xbacks and HBRTG because of the Malaysian genetics where the blue base from the Xbacks originates. HBRTG is a cross between RTG and Malaysian Xback. It also can have the blue base.
Normal RTG is from Indonesia, the blue base is less common as it's not really a distinct feature, although it does happen from time to time. If the RTG was to have a really nice natural blue base and normal 4th level gold shine, it's still a RTG. If it goes to the 5th level of scales, then it would be a HBRTG. When the aros are young, it's impossible to tell them apart and breeders determine the quality of the RTGs by the parents, and assign this to the certificate based on this. HBRTG is really like a roll of the dice. You could end up with a really nice fish, or you could get a normal RTG. Xback always you get the best quality fish, and you pay premium for it.

Blue base or not they cost the same as any other RTG. As breeding is behind the fences of each farm, how sure can one be that HBRTG are truely a cross of RTG and crossback? To achieve blue base or high shine not neccessary mean must cross bred with crossback this I can tell you.

Some even sell their slow developing crossback as HBRTG but eventually these fish will still develop over time in the right condition. That's why I question some people by asking, if a HBRTG can look like a crossback, then a crossback should look like?

As the standard of hobbyist become higher, previously any extra shine on the 5th row of a RTG is considered a HBRTG. But now, hobbyist demand that there should be a row of shine on the 5th row then considered HBRTG.
 
Glad you posted Koji, perfect person to answer this.
I have a HBRTG according to the certificate from QH farm and checked this with scanner over the microchip. My HBRTG looks like a normal RTG. No proper shine to 5th level yet. I have another normal RTG from QH this RTG has more shine to 5th level and than the HBRTG, and has a natural blue base. They were chipped at the same time according to the certificate (march 09). At a young stage the fish all look exactly the same. How can these farms determine whats what besides the certain fish being in the pond and removing the fry from the brooding fishes mouth ?
I have been keeping aros for a while and I know my certificate HBRTG is not HBRTG unless there is some serious late development that happens. Does this happen ?
I had reds in the past that are late developers but never RTGs.

When you guys say that the aro's 'develope late' how late? Like if an RTG is sold off as an RTG on the Cert. and really it is a HBRTG but developes late... How late are we talking about? 16"+ ? 18"+?

High shine development is all in the genes. We will keep all RTG in white tank to provide an enviroment for those which can achieve high shine together with those which couldn't. As for late developer, I will say RTG can reveal themselves pretty fast within their 1 year of age more or less.

And to be frank, even if the brooders are highback RTG looking fish they may also produce classic looking RTG of 4th row shine only. And I have classic looking brooders which give me high shine RTG off springs.

Another thing about the tag date on the cert, it's not the birth date of the fish. Some farm may practice early tagging of their fish when they are small but some will tag their fish when they are bigger or when they are been sold. Thus the tag date is just merely a rough gauge of the age.
 
I agree with Koji. It seems you are misinterpreting the potential of the fish. Having a HB lineage does not gaurantee that your aro will turn out going HB. It has the potential to achieve 5th or 6th level, but that doesn't mean your aro will stay at 4th level shine. Too many factors contribute to whether or not the fish will reach HB. You're expecting a definite result from something that is unpredictable.
 
sometimes RTG at different angles,you will see blueish on the scales
