Strangely coloured spec­i­men of P. linkei was cre­ated by Peter Finke
A very suc­cess­full Ger­man breeder, Stephan Men­zel who lives in a peat region in the Harz moun­tains (with black­wa­ter float­ing just in front of his house­door) found a specif­i­cally coloured P. linkei- female among the off­spring of one of the last clutches: it is nearly non-​coloured except of the two black blotches on the sides of the body. Any other colours (the nor­mally over­all sil­ver­ish or brown­ish tinge of the whole body, edges of fins, red dots in the blotches’ region, glit­ter­ing colours of the scales) are very much reduced. We have observed this phe­nom­e­non with many other fish already: they are no “albi­nos”, but they are strangely pale and are often bred in this non-​colouring as spe­cial forms which swim in many tanks).

In this case there are two spe­cial­i­ties: firstly, that is the first time we observe this with a Parosphromenus, and sec­ondly, the black blotches at the sides of the body are present.

Unfor­tu­nately, it is one fish only, poten­tially a female (it’s only about four months of age, so one could not be fully sure of the sex).

Undoubt­edly it would be inter­est­ing to breed with this ani­mal (and a sex-​partner out of it’s brothers/​sisters). Stephan will be glad to post a pair includ­ing this strange spec­i­men in some weeks time when the sex could be deter­mined safely. Is any­body inter­ested? He would even try to post it across the country’s bor­ders if nec­es­sary. Now, in sum­mer, this could succeed.

I am not sure I under­stand why would it be inter­est­ing to breed this ?

That sounds inter­est­ing!
Do I under­stand well and are even the black lines on its body reduced, but the spots still present? That seems quite unusual…

Bart­ian, yes you do: the black lines are reduced but the black blotches are shown.

And, Helene, why should one try to breed with this fish? Well, in order to know about the dom­i­nant or reces­sive char­ac­ter of that fea­ture. To say it clearly: I do not like any such vari­a­tions as per­ma­nent inhab­i­tants of our tanks (as there are many exam­ples with other fish fill­ing the tanks in the hobby stores). But we should know whether this is a sin­gle event in a sin­gle spec­i­men or whether some sort of genetic hered­i­tary dis­po­si­tion is slum­ber­ing in it. You may take it as a hid­den dan­ger.

It was Horst Linke who told me this should be tested by try­ing to breed with this fish. And I think he is right although nobody of us likes it.

Hello, few weeks ago I had a plea­sure to meet Ste­fan and even pur­chase two species of Parosphromenus from Him (one more time thank You Peter for man­age this meet­ing). One of them was P.linkei which already spawn in my aquar­ium (yes­ter­day I saw few lar­vae in a film­box cave). I have a plan to try inten­sive breed­ing method for one pair and I’m won­der­ing that maybe such an “albino” spec­i­men ( Ste­fan show me this female also) will appear also among my off­spring..? Dur­ing next weeks , I will add some pic­tures of my new parosphromenus because they are very beau­ti­full and worth to show..:) Greetings!
