In our last post, we men­tioned Parosphromenus fil­a­men­to­sus, bred by Aqua­zoo Düsseldorf.
These fish was kindly given to the Aqua­zoo, by Thomas Beu, a long term breeder of paros, and also longterm friend and breeder witin the Parosphromenus Project.
The P. fil­a­men­to­sus are from trade, and was bred by Thomas Beu since 2010.
This week we will bring a few more of his pho­tos, — and by the way – did you read his arti­cle about breed­ing p. filamentosus ?

Its in ger­man, but for those who under­stand ger­man, it’s a really inter­est­ing and great arti­cle which you can find it on our home­page along with other inter­est­ing articles.

The Parosphromenus Project have estab­lished a coop­er­a­tion with Aqua­zoo Düs­sel­dorf in 2021, and received Parosphromenus fil­a­men­to­sus from Thomas Beu, — a long term mem­ber of PP, — and in the Fall Cen­sus 2021 Aqua­zoo Düs­sel­dorf reported suc­ces with breed­ing these, with 30 off­spring. We con­grat­u­late Aqua­zoo Düs­sel­dorf with this. It is a great achieve­ment, and helps us secure this par­tic­u­lar line of P. Filamentosus.

Happy New Year

Dear all.
From the Parosphromenus Project we wish to thank you all for all your ded­i­cated work and coop­er­a­tions on so many dif­fer­ent fronts, pri­vate aquar­ists, with breed­ing, help­ing each other with dif­fi­cult prob­lems, shar­ing, as well as the grow­ing num­ber of insti­tu­tions which sup­ports our work.
We are exited to enter 2022, we already know exhit­ing new things will unfold and we are look­ing for­ward to shar­ing those with you.
But first af all, enjoy the last hours of 21 and get well into the next 🎉⭐️💥❤️
Many kind regards the team behind the Parosphromenus Project.

Parosphromenus bin­tan ’Bintan’.For the new con­ser­va­tion project of Parosphromenus Project, we imported some Parosphromenus sam­ple from Bin­tan Island. Col­lected by a local friend, who lives in Bin­tan Island​.In a post from Feb­ru­ary Went­ian Shi wrote in Jour­ney to the water that some inter­est­ing obser­va­tions of this imported fish, raised the ques­tion – or ques­tions : Either the orig­i­nal P. bin­tan was not entirely blue, as described, but has a small inte­rior band of orange red, — or there may be a sec­ond species/​type on the Bin­tan Island.
I received one male and two females of this species in spring 2021, — with the intend of breed­ing – and try to doc­u­ment with photos.The breed­ing attempt was very suc­ces­full, — the off­spring now is around 6070, but the doc­u­ment­ing less a suc­cess. The male has spend most of the time in the cave, — and the few pho­tos I have taken were not the best, — how­ever heres a few of this very strong and beau­ti­ful species. Helene

Parosphromenus Series 8.1, P. kishii

Mys­te­ri­ous as Nebula

If jueli­nae is one of the most beautu­ful species in my eyes, kishii is cer­tainly the most var­ied species I have ever met until now. The cau­dal fin pat­tern of kishii is never same. On the certer of the dark red cau­dal fin, there scat­tered many irreg­u­lar blue blotches with ran­dom sizes, which form ran­dom pat­terns with­out con­stant or dis­tinct bound­ray. just like the Neb­ula, every spec­i­men, dif­fer­ent. The blue color of thee blotches are also strange, it is not those com­mon met­alic blue like other paros, eg, bin­tan, deiss­neri, har­veyi etc, but a mys­te­ri­ous light cyan color.

These blotches also dont stay like that, they change and develop with the time. Juve­niles hava a full red cau­dal, the elder the larger the blue parts and more com­plex the pat­tern. Fur­ther, even the cau­dal shapes are never con­stant amony them. They can be rounded, can be sharply pointed in rhom­bic shape (which is most com­mon), can even have a short fila, some­times even in a non-​convex shape .… Even among the off­springs of the same breed of same par­ents, there can be dif­fer­ent shapes.…
You never know what you will get.…
