Yep. You have to remember that anyone can set up a youtube channel, it doesn't mean they're an expert, even if their tanks look beautiful at first glance.
George Farmer is a famous, talented aquascaper, who creates incredible aquascapes, and also has a YT channel that's worth watching if you're into planted tanks and aquascaping. He knows his fish stuff too, but his focus is on planted tanks and aquascaping, naturally, since that's his area of expertise, and he's incredibly good at it. But he'll admit himself that many aquascapers set up a stunning tank, work on it for six months or more to get the plants grown how they want them, often in high CO2 since that's the best for plant growth, but they're growing and building the tank for competition or shows, will stock the tank just for the occasion, then tear the tank down. The show aquascape tanks you see aren't your general, long term, hobbyist tanks that always look that stunning, with those fish and shrimp living in them full time.
There are also a lot of "fishtubers" and "pet-tubers" out there with zero real knowledge, merely collect animals for clicks, because they have an audience of children who don't know any better, and just want to see the pretty fishes and cute animals. "Catch em all fishing" and his gang of friends are one such group, that create videos for clicks, don't actually care about fish, or their welfare, or keeping their aquariums and stocking long term. For them it's all about the money, they have kids that watch and don't know better, and they're raking in the money. Which lets them pull more outragious stunts, make wild claims, and set up fake "rescues" where they've dumped fish they bought into a swimming pool or something, then claim they just found it, and they're gonna catch it and save it.
Not all people on youtube, or anywhere, for that matter, are well intended, or as expert as they pretend to be. Cynical, but true. Be selective in who you watch, always take it with a grain of salt, as Colin says, and bear in mind that even "good" fish youtubers, like Aquarium Co Op, for example, know a huge amount, and has good intentions, along with also promoting his businesses - but that he IS also promoting his businesses, and that his knowledge isn't flawless in all areas.
So, grain of salt, even with good youtubers.
