nice we thinking same on most except with highfin i yet to decide . these have not been studied by scientists so we do not know what group went were or if was decade ago 50 years 100 etc only god knows . last i did research on green body most info says green body is 200 and blue is 128 so we can not go off info peoples ideas or guess as i can not find any scientific info on them yet to be researched so how can any one state anything without scientific info we do not even know were they sourced do we really trust the collectors $$$128 - blue phantoms are darker green with blue tinges to their fins... how blue varies within the species
200 - green phantoms are a lighter shade of green and in some examples have slight yellow tinge to the fin edges
general rule of thumb is spots continue full length in 128's and often has a few spots on tail also. the green phantom generally has less spots on the rear of the fish....
i have owned blues and greens and the odd fish will differ... i had one green phantom with spots all the way to its tail... and a blue phantom that has its spots thin out towards back end of the fish like most green phantoms do... but when you have both varieties together its easy to differentiate...
spot numbers vary on leopards greatly - just the same way it does on fish...
i believe the blue phantoms and green phantoms are definitely related.... many years ago a group of greens went downstream and their colour evolved over many years into what we call the blue phantom... so blues described as hemiancistrus and the greens baryancistrus...
but how far do you want to relate fish - all L-numbers had to be descended from same fish at some point in their evolution...
as stated did research most say green colour half spot is 200 and blue colour full spot is 128 note none state there are full spot 200s or less spot 128 sounds like have to own them to know . just ask your self if they cross breed ok some will look 200 and some will look 128 then you have some in between both colour and this pic perfect example of it green head and body just shadow making darker but fins white blue were the question mark is all my 128 body darker not green again no forum states 128 can have green body unless u can read german . i had a 5cm 128 full spot grew it years now and almost half spot you can notice spot or spots fading as become adult some loose more than others some loose none also colour can stay or decrease 75% of my 128s lost there white band on tail also 75% of my 200s lost there white yellowish band on tailplanetcatfish has a fair bit of information on 128,200,200a perhaps you should have a good read of their information... and then theres a handful of good german websites that also have more info in depth on these fish... you'll prob need a german buddy to translate it properly - i tried using a translator off the net to convert it and a lot didnt make sense.... made more sense after my mate told me :thumbup:
every phantom i have owned or ever seen in the flesh was easily distinguished as one or the other....
heres your hifin comparrison - easy to see the difference now

you bet they can told u natt yours are top quality 200s do not be fooled by full or half spotSo L200 can have spots all the way down the tail? That's good to know and makes me a happy chappy
