the weirdest thing is that the dude said the sharkcaino 'mutated' the sharks. Like volcanoes area not radioactive, and even if they were, radiation just kills things, it doesn't actually turn them into monsters.

[@KestrelDC]

Yeah, radiation can give some gnarly mutations and deformities but even then and even if not lethal it’s not really the Hulk or Resident Evil sorta thing. It’s more like malformed limbs, extra fingers, abscesses, harlequin ichytosis, etc. Not becoming capable of just casually hanging out in volcanoes. Idk why people think radiation works this way just because comics and movies take artistic liberties with it. It baffles me how so many people are so incapable of differentiating these things from reality. Not blaming the comics or movies, though, I’m blaming the people for being dumb.

[@makodolphus7810]

Volcanoes can actually be surprisingly radioactive- but it is entirely dependent on what kind of material is present in the volcano's system, which tends to just be "above trace" levels of long-lived radioisotopes.

Microbiologist here, when the guy was talking about the fish "not being able to speak to each other" he was probably referring to quorum sensing. Biofilms on fish scales give signals between other bacteria which allows a fish to glow for communication purposes. I know deep sea fish do it. I don't know if goldfish do it, but I wouldn't be surprised if they can give off a faint signal or one outside of the e-mag spectrum of human vision.

The person making a speach about the Glofish is actually Heiko Bleher, an ichthyologist who discovered hundreds if not thousands of fresh water fish and has written plenty of books about them.

heiko Bleher (born 18 October 1944) is a German researcher, author, photographer and filmmaker best known in the scientific community for his contribution to the exploration of fresh and brackish water habitats worldwide and the discovery of many species of fish and aquatic plants, several of which carry his name, discovery location or are named in honor of Bleher's family. Heiko Bleher was born in Frankfurt on Main, Germany. He is the fourth and last child of Ludwig Bleher and Amanda Flora Hilda Bleher, born Kiel. Bleher inherited his passion for freshwater fishes and aquatic plants from his mother Amanda Flora Hilda Bleher was the daughter of Aolf Kiel - "Father of Water Plants" and pioneer of the modern aquarium starting in 1887, who established the world's largest plant and ornamental fish farm in Frankfurt am Main, Germany, in 1900. At the age of 4, Bleher’s mother took him to Equatorial Guinea, in West Africa on a research expedition and 2 years later he accompanied his mother on a journey throughout Europe collecting plants and fishes. By age 7, he and his three siblings joined their mother on her adventurous exploration trip deep into the South American jungle, where they lived with natives. During this 2-year expedition from 1953 to 1955 his mother discovered many new aquatic plant species, fishes and other animals. At the end of 1958, Bleher's family settled permanently in Brazil and established a water-plant nursery and fish-breeding hatchery called "Osiris" in the jungle outside of Rio de Janeiro. In 1962, Bleher moved to the US and later attended the University of South Florida, studying courses in ichthyology, biology, limnology, oceanography, parasitology, combined with the work at Elsberry's Fish Farm and at Gulf Fish Farm. Two years later, after his return to Rio de Janeiro, Bleher established his own export company "Aquarium Rio" and continued his research and collecting throughout Brazil. At the end of 1964 Bleher introduced the first new species to be named after him, Hemigrammus bleheri (the brilliant rummy-head tetra) to the aquarium hobby. Bleher contributed to the rainbowfish species community by introducing Melanotaenia boesemani this being one of the most popular rainbowfish in the hobby and many of the other almost 100 species of Rainbowfish. In 1970 Bleher was the first to collect live Pterophyllum altum from Venezuela The tetra Hemigrammus bleheri, Leporinus bleheri, Bleheratherina pierucciae, The Cichlid Steatocranus bleheri, The Snakehead Channa bleheri, The African Tetra Phenacogrammus bleheri, Moenkhausia heikoi, The Rainbowfish Chilatherina bleheri, The Bromeliad Vriesea bleheri, Hyphessobrycon amandae is named in honor of Amanda Bleher (1910-1991), the mother of Heiko Bleher, who collected the type specimen and because of her interest in and her knowledge of the freshwater fauna and flora of Brazil. In 2012, Bleher was accused of plagiarising image(s) of fishes, submitting them as his own for an article for Practical Fishkeeping Magazine entitled "PFK's Definitive Guide to Channa". In 2019, Bleher was again implicated in another plagiarism scandal whereby a number of images of freshwater fishes were used in his book "Indian Ornamental Fishes Volume 1". The images were in fact the property of a well known blog writer based in India

I get the Glo-fish hate but it's not really that bad of a genetic change. Using transgenesis, you can insert a gene that produces a naturally occurring fluorescent protein in the fishes tissues and breed them for several generations. It doesn't significantly change the genome of the fish, except that they glow. It's not that far off of nature, many fish already have bioluminescence anyway.

Some local areas have had contests in local rivers on who can catch the most plecos to try and limit their numbers, but there’s so much vast rural area and so many lakes here that it may be impossible to get them under control.

I was watching the stream during this (you can see me chat a few times) it was the first time I made it to a stream. Love the videos!

I LOVE Leopard Danios. That's because they have the same shoaling behavior as normal danios, but their fins are flowy so they look like they are tiny ballerinas moving around in a murmur pattern in your tank. I know starlings are an invasive species, but I can't help but appreciate their huge murmurs as they dance around the sky like a dark cloud on acid. Leopard Danios are like that, but only for your aquarium. I can stare at them all day.

What I learned from this video is that there are mutated volcano whale sharks in Mexico. Thanks for the warning.

Platys are my mom's favorite. Actually yelled out loud from how offended I was that he said it's no one's favorite.

[@Glockboy45]

I’ve caught a pacu with meat in a pond at my apartments I was so confused because I live up north near the Great Lakes and they’re not a native species so someone obviously threw him in the pond but later that year when winter came the poor guy died but they put up a great fight and are really cool to look at

[@videlvasq]

funniest chat message of this one has to go to that person who said "i should call her" when they saw kissing gourami

[@Ne0LiT]

found it hilarious when people in chat mistook the music from " Brave Heart " for Titanic or LOTR music at 7:30, lmao

My dad had four turtles as a kid. He took pretty good care of them. Up until the end, when he took them into his backyard and of course you take your eyes off them for one minute and they’ve disappeared. I think about how the invasive turtles I see today are descents of my dad’s turtles.

The sharkcano I'd just so ridiculous I wouldn't be surprised if it's parody.

[@therealgd]

why go to therapy when avnj posts fish😃

[@turtlejeepjen314]

ROAST AWAY!!!🙂🙂I seriously WAIT for these vids- but I DID learn a couple of things, too- I wasn’t expecting that, being TikTok & all, but it IS much appreciated!! (The info about classifying a new species, & the fishing PitBull Dogs- all new to me!!)🙂🙂

I loved my pleco as a kid, kept him with my fair-won goldfish in a big ol tall tank

[@troyrussell177]

2:52 arapaima got these rock hard heads, And they jump the water and thrash their head 24/7. Bad description but Its a species trait. They've killed people like that, usually in the workers in arapaima farms. The fact that guy just jumped in there with the fish thrashing right near his head is wild. He took a risk

[@Raych3lwastaken]

You should of called then “Fish-Toks”

[@CoralReaper707]

To be fair, National Geographic has covered this so called "Shark-cano"

[@kuufytaro1933]

The part where he was talking about how fish dont get full reminded me of the time my dad accidentally overfed our bearded dragon and its stomach burst.

[@ariesdemiurge]

12:12 Oh hey, I think that's that spot in Google Maps that blew up when people thought it was the scene of a murder!

[@kuitaranheatmorus9932]

This video was pretty funny & very educational as always so that's good :3 Hope y'all have a great summer

[@CJCroen1393]

That fish who escaped was totally thinking “SO LONG, SUCKERS!!!!”

[@LacerdaIsAWeeb]

TBH, I believe the Pacu story, since a lot of indigenous people swim totally naked along them.

[@TheWatcherinthewalls]

I was doing a project for a class the whole forest thing was actually just a sinkhole that opened up, underneath the sinkhole there was a cave that housed an ancient forest with undocumented bacterial species I believe.

[@pochorojas4950]

Here in Spain invasive especies where introduce during the past century and now most of the regular Spanish wild aquatic ecosystems are now in highly risk. In the fisherman video: Could it be a Siluro (huge catfish) instead of an Arapaima? They can be really huge and strong

[@areallydepressedfish5201]

I love platys *instantly evaporates*

[@Major003]

I think the sharkcano guy just wanted _so_ badly to create his own spinoff of the Sharknado series.

[@user-kn8kh1bw1k]

Some people released goldfish in a lake near where I live and some of them are killing the baby sockeye salmon 😢

[@Barakon]

The turtle either dead or had just invaded your childhood river.

Somebody tries to say something about fish. AVNJ: "Fear mongering"

[@blindopossum7913]

Bro I realized that I was over feeding my fish when they looked super pregnant but were all males. I started feeding them once a day and they finally look normal.

During the start of the Glow fish chapter I think the guy meant that they were so genetically different that they cant interact with their parent species like they would if they weren't modified When he says "they aren't able to speak to each other" he most likely mean that in a metaphorical way, everyone knows fish don't speak

[@panzerwolf494]

Not sure about the kissing fish, but when I introduced a new crayfish to my tank some time back the male ran over and immediately burrito'd her and got down to the mating business

[@amazingaquaticsandexotics3030]

love your content

[@LordOceanus]

There is exactly one reasonably plausible story of a Pacu attacking a man's little man but that's one person out of millions who go in the water with these fish every day.

[@ezraskogerboe1464]

North woods. It’s a fishing term in Minnesota, like Bemidji aka the land of 10,000 lakes would be referd to as back in the north woods. That kinda thing
