Gastromyzon with the strange pattern

Gastromyzon with the strange pattern is in my tank at present.
G.Stellatus? with the design by which a fleck crowded very much .
Neither be the pattern of the body of Gastromyzon invariable nor do it sometimes change big?
I think newcomer's time was probably striped G.Zebrinus.

Seeing the Blue in the caudal I would agree with G. stellatus, the ones I have had in the past have shown quite a bit of pattern variation between individual fish.

Looking in Dr. Tan's book, this fish looks very similar to Gastromyzon punctalatus. The main difference is that the true punctalatus (not what is now called ctenocephalus) has yellow in the dorsal and tail.
Very nice fish!!

It's defiantly a different species.

Hi, everyone.
Thanks for advice.
This Gastromizon is quite timid. Therefore a good picture can't be taken easily.
The pattern of the design has changed into this Gastromyzon big in 2 months like upper pictures.
I recognize that it was ordinary G.zebrinus at the time of purchase about 1 year ago.
I'm sometimes disturbed by G.zebrinus and G.stellatus.
Was a change with its design completed?
When a white part increases any more, it may be white Gastromyzon!
The pattern of old G.zebrinus has seen the phenomenon fading away several times.
I'll also observe well from now on.

yes I know. I nearls fell off my seat.
dr tan says he watched about 300 of this species im the wild and it's true.
they are different in pattern and colours.
imortant is the breeding now. not so easy as sewellia.
as a matter of fact I count now 7 species in the trade: ctenocephalus, farragus, ocellatus, stellatus, scitulus, viriosus, zebrinus.
as farragus (I have only two) is rare in pictures I join some. may be one for the index?

hi there
i also asked Dr. Tan some questions...
as he catches the loaches out in the wild. they transport them to take the photographs in a tank, and it is hard to keep them alive as there is no electricity to support them with oxygen.
he wrote he has not really experience keeping any of them in the tank...as they work in the field!
so he could not give me and hints about waterparameters how to keep them and what makes them to mate...no clue at all as he does not keep them in tanks...he guessed it's the mass of fresh water and ph over 7!
one thing is clear non of them has been bred yet! he was even curious about how to breed sewellias...what surprized me a bit

Wow! Great pics and info! Thanks farid & ch.koenig! Amazing variation in the zebrinas, any idea what the determining characteristic/s are?

you mean all of them?
I love all seven species, but ocellatus are special an farragus are alike: they have the most extensive social life of gastromyzon and they seem to be the curiest and cleverest. after work it takes me only minutes in front of the tank to relax and settle down.
about breeding: gastromyzon monticola has been bred once in germany by p.dickmann. article not available, but I could resume it if needed.

Hi folks!
The pattern of their surface of a body is full of variations.
I think that the relations with G.farragus and G.ocellatus resemble relations of G.zebrinus and G.stellatus , G.ctenocephalus and G.scitulus.
Is not there the possibility that is in state that it is the extremes of the variation of the pattern of their surface of a body?
Do both have the boundary line if it is not a continuous variation?
Is the difference of the pattern of the surface of a body synonymous with fish classes being different?
Will that design be the fixed pattern that does not change throughout the life?
Will the difference of the fish class be identified by DNA analysis?
I cannot sleep at night when I devise it!
I introduce below a Japanese website.
"NekoMaru" makes the site not my site.
However, I offered the most of pictures used in the page several years ago.
