About the author

Born 1981 in Dortmund, Germany, I’m currently dwelling in Austria’s fine capital of Vienna. I’m an active aquarist with special interest most notably in gobiid fishes and the peri-mediterranean freshwater fauna. Lucky to have found a job that suits my ambitions, I’m working as a freshwater fish zookeeper at Haus des Meeres (House of the Sea).

That said, after all this site is really just my very personal account of trying to find an outlet for the these days seemingly so common need for letting the whole world know what one is doing and thinking. Should you feel like sharing information or chatting about common topics of interest, you’re free to contact me any time via eMail at paul (at) inorganic.de or just drop me a comment here.

I hope you enjoy your visit!

Paul

  1. Hello,

    I am French, I was fished wingeis in Vénézuela in 2012, in Cumana, Cariaco, Campoma and Aguas de moises Rio de oro…

    I learnt that too, you were there in 2006.

    I would like knowing if you have photos of fishes fished to Aguas de moises? And if you returned it?

    Thank you very much

    Fred

  2. Hallo Herr Eckstein,

    Jutta Bauer hat sie empfohlen. Ich bin auf der suche nach Rhinogobius rubromaculatus, für unser Vereinsbecken. Ich bin aber in Tirol zuhause. Würde mich über eine Antwort freuen.

    LG Michael

  3. super das deine website wieder up to date ist!!! tolle Fotos und super interessant um zu lesen. gr. Ma

  4. Hallo Herr Scheffel, das tu ich natürlich gern:
    Gil, F. et al 2010: An Efficient Technique for the Captive Breeding of an Endangered Freshwater Fish Salaria fluviatilis (Pisces: Blenniidae), with a Description of Its Ontogeny. Journal of the World Aquaculture Society 41(S1): 49-56.

  5. Hallo Herr Eckstein,
    Sie erwähnen eine portugisiche Arbeit über die gelungene Aufzucht von S.fluviatilis aus dem Jahre 2010. Sind Sie so nett und nennen mir Autoren, Zeitschriftentitel, Zeitschrift, Volume, Seitenzahlen damit ich an die Schrift komme?
    Gruß
    Hans-Joachim Scheffel

  6. Hallo Herr Eckstein,
    ich habe den Kontakt zu Ihnen durch Michael Taxacher bekommen.
    Da ich bei ihm nachfragte, ob er Padogobius bonelli abgeben könne, sagte er mir er habe diese Spezies nicht, aber eventuell hätten Sie Tiere zur Abgabe.
    Daher also meine Frage an Sie, hätten Sie Tiere zur Abgabe?
    Ganz liebe Grüße,
    Alexander Brenneis

  7. Hey,

    wirklich tolle Website, freue mich schon auf neue Sachen. Falls du Interesse an Lebendfotos von Knipowitschia goerneri haben solltest, ich habe noch ein paar Aufnahmen von meinem letzten Korfu-Urlaub (Korissia-Lagune). Die Qualität ist aber nicht ganz so gut. Wenn du sie trotzdem haben willst, kontaktier mich einfach.

    Grüße und noch viel Erfolg mit deinen Fischen,
    Jan

  8. Hi there, well my R. candidianus are still unwillig to breed. But one thing’s for sure – R. candidianus is a strictly freshwater species, so it’s definetely non-amphidromous and does not have any larval stages needing saltwater. Goby systematics is crazy, though, and especially in aquaristic literature the different species have often been confused. In the R. brunneus complex, there are quite a few species that look somewhat similar to R. candidianus, and many of those have a much less-abbreviated larval development. But if you buy the real R. candidianus, it can without a doubt be bred in freshwater. Unfortunately, that doesn’t mean it’s as easy to breed as e.g. R. duospilus. The main problem seems to be getting the little buggers to breed at all…

    You can email me if you got further questions!

  9. Hi, thought I’d ask another question have you managed to breed your candidianus? I’ve seen conflicting information on the needing saltwater?

    Btw if you post on any forums can you say which ones? I have a lot of questions on Rhinogobius species as I’d like to know a species before i buy them.

  10. @paul: I finally got some news for you. The putative father of my R. candidianus died after 8 years of existence. So this really seems to be a pretty long-lived species.

  11. @Paul: Cheers Paul and thanks for the positive feedback! I’ve only been keeping my R. candidianus for about 2 years now, so I cannot really tell you much about their lifespan. I mailed the guy I got them from, he’s been keeping and breeding them for quite some time now and should be able to give a more substantial answer. I’ll let you know if I get an answer, actually I’m curious about it myself, presumably they’ll get pretty old for such a small fish.

  12. Hi, nice to see a Goby fan and you have some lovely pictures of them. I’m interested in getting some Rhinogobius candidianus, do you know what their life span is?

  13. @eric: this seems to happen especially with young, unexperienced pairs or when the breeding couple gets disturbed (like in overcrowded, too small aquaria) or under otherwise unsuitable conditions. but chances high are that the male will guard one of the next broods successfully, just be patient, observe and make sure conditions are optimal. thanks for stopping by and have fun with your moggies 😀

  14. hi i have a pair fo fruata gobies that are breeding, they have laid eggs before but they end up eaten, it apperars the male (larger one) guards them after they are laid, but they still end up gone. my question is will either of the parent gobies eat the eggs?

  15. Hai Paul, echt tolle foto’s von Deiner “Familie” Knipowitschia C.F. Thessala !!! Viel Erfolg mit Deinen neuen Suesswasser Grundeln. Bin gespannt wie es weiter geht – mit beiden Familien….
    groetjes Ma

  16. Hoi Paul, heb met intresse je site gelezen. Ik begrijp nu ook beter je studie-richting. Ga zo door.
    Groet Th.
