I have a youtube account, but I don't put anything up there.
Danios - Why they're good. While danios are technically cold water fish they're highly versatile and can withstand most temperatures and water conditions. Like all fish it's better to keep them in their preferred environment, but they're pretty darn indestructible. They're also pretty easy to breed, extremely active and if you keep them in fairly decent conditions the most friendly fish in the tank. In fact, when I moved my molly from the 10 to the 29 the danios took the largest of the two fry I had into their shoal. Unlike my mollies, they don't eat my plants.
The only downside to danios I can see is they're almost impossible to catch.
