Freshwater fish from Japan - 30 species: Gobies, Coreoperca and Silurus! Japanese Freshwater fish

[@jpemydura4860]

That public aquarium looks awesome. Thank you Oliver for shedding some light on some of the lesser known freshwater species.

[@belowwater]

Glad you enjoyed it!

[@michaela-be4le]

The fact that most of these species were unknown to me is clear indication that more of this kind of content is required.

[@belowwater]

thanks, we were aiming for doing new stuff!

[@NateK-MN]

Loved this video! Can't wait for the goby and medaka episode!

[@belowwater]

thanks. Coming soon!

[@absolutelyunepic3072]

I really hope some of these fish like rhinogobius get more popular and thus cheaper

[@LeandroSousa_IctioXingu]

Very nice! All these were new for me! Thanks for sharing!

[@belowwater]

Thank you. Ituglanis would be so confused in that habitat, like the population has turned into aliens that look like them.

There is an article about Coreoperca kawamebari (then known as Bryttosus kawamebari) in German magazine DATZ, issue 7/1995. A number of fishes were brought back to Germany from a japanese aquarium shop. They were quite aggressive towards each other, but otherwise easy to keep and fed with live insects, earthworms and fish. Spawning took place on a vertical substrate, e.g. the aquarium glass. Raising fry was easy according to the author. There was a remark at the end that the species might be able to reprodce without a partner, since a single animal produced a viable spawn separated from its partner by a wire mesh.

[@belowwater]

yes I remember it, it was one of my first aquarium magazines!

Love the video! I love Asian fish. When I was in Taipei I saw a bunch of wild mudskippers hanging out on a piece of garbage foam floating in a river. The habitat didn’t look very complicated. It was amazing to see them despite the garbage.

[@belowwater]

well, that is not their normal place. They are usually in mangroves, and go from dry to wet, also they are territorial, so they need a lot of space....

[@amsterdamaqua]

Inspiring video, thanks! Asian fish seem to be generally underappreciated - especially in the US, but in Europe, too.

[@belowwater]

thank you!

[@alekkoomanoff7281]

More gobies and the giant salamander, please sir. Your knowledge and organizational skills allow you to present an amazing diversity of species in a brief period of time.

[@belowwater]

thank you, we are working on it, it will come in the next few videos!

[@deborahcheney432]

Thank you for sharing. I find your content facinating!!

[@belowwater]

thank you!

[@thunderfalkfalk5590]

Great video !

[@belowwater]

Thanks!

[@thomascallaghan5988]

Brilliant video

[@belowwater]

thank you!

A couple of years ago I had the oppurtunity to visit a public aquarium in Seoul. It had a room dedicated to native freshwater fish and I was stunned to see rare catfish, salmonids, loaches and cyprinids, never mentioned in popular western literature. They also had a very impressive species of freshwater perch, one of the most beautiful predatory fish I've seen. Unfortunately I forgot their name (Siniperca, probably, but I'm not sure).

[@belowwater]

there are several really nice Siniperca, my guess is S.scherzeri, roulei or chuatsi

[@andrewsager7928]

Great video. 👍👍 Really interesting looking fish. Can't wait to see the next videos of your trip. :)

[@alkgugl8925]

Спасибо большое! Очень интересно. Ждём с нетерпением Ваши новые видео.

[@belowwater]

Спасибо

[@drockingfish]

Awesome!!

[@fischverruckt7321]

Very interesting! Thanks!

[@Someoneonthisplanet1979]

another great video with most species that I have never seen before. Thank you for your work and sharing is with us!

[@belowwater]

Glad you enjoyed it!

[@stevenbisset8717]

another amazing video, now this is brilliant seeing these fish for the first time, would make really good biotope type Japanese aquariums I would think most plus no heater required maybe a cooler for some , do Japan export any speices

[@belowwater]

Afraid not, some similar fish are available from China, but there is just no market for new fish.... people want the same species they know! Same goes for the unusual fish from India.

[@stevenbisset8717]

thought so, great to learn about different thanks great work 👍

[@roten2902]

danke dir tolle fische...😉👍👍👍

[@belowwater]

Danke!

What size city was this aquarium located in? I'm in the twin cities in Minnesota and there are sporting goods stores that have giant native fish displays, but the behaviorals are nothing in that their big display fish seem suspended animation, there's a 10,000 gallon tropical pond at the Como zoo that has big pacu and two species of Midas like cichlids, and a separate smaller pond with stingrays and a webbed footed turtle, I'm forgetting the name put footage on my channel of it but need to find out it's nomenclature. I recall you being in canada, in your travels have you seen in the United States a display tank similar to what was shown off here in Japan displaying natives? The habitat replication in those tanks were spectacular, the troutish ones specifically

[@belowwater]

the best native displays i have seen in North America are at the Tennessee Aquarium. This place is in Gifu, which is roughly the size of Minneapolis, but sits near the "hot spot" for Japanese freshwater diversity.

[@MarkDrisch]

today is a good day.

[@sandyman7340]

Please do the rare and unusual loach video!

[@belowwater]

sadly i do not have the footage for that. Would be a great idea.

[@Ian-qw1zb]

The origin of the imperial loach or leptobotia elongata, the largest botia loach in the world..

[@belowwater]

_L.elongata_ is from China, Yangtze river basin, i think all 15 or so species in _Leptobotia_ are only in China.

[@wasp586]

What climate zones are they all living in? Mostly southern islands, or more northern?

[@belowwater]

A lot of these fish are from the Nagara, so the region around the town of Gifu, Lake Biwa etc. Central Japan

[@wasp586]

@@belowwater so that's all still pretty subtropical then?

[@belowwater]

@@wasp586 yes. Not so warm in winter!

[@harveymogarawanderingfilip5318]

Can you do Philippine freshwater fishes for the next Asian fishes episode?

[@belowwater]

I wish, but never been to the Phillippines!

[@kjeaquatics]

Is there an interest in Japan with keeping their native species?

[@belowwater]

At the moment the Medaka is huge and everywhere, but the hobby is not as organized as it is in the west.

[@kjeaquatics]

@@belowwater I like the rice fish but have zero interest in them because they are so popular. You’ll never see me keeping neon tetras either lol

[@ケロニヤケロンニア]

最初のナマズ、ビワコオオナマズではなくて タニガワナマズSilurus tomodai だと思います。

[@belowwater]

Thank you, too bad i can not fix it on the video, i corrected it in the description.

[@belowwater]

訂正をありがとうございました。ビデオの修正ができないので、詳細に書き込みます。

[@mauricematla8379]

Shame these are almost never availble in the European hobby. Some good candidates for a unheated living room tank i am sure.

[@tacojoey]

What the bluegill of Japan

[@belowwater]

the fish that looks like a sunfish is Siniperca, there are more species in China and Korea as well

[@klausoxen6597]
