this is really not gonna sit well with many people but I have to say it
Really it is a youtube video and there is nothing that I can do about. And at any rate I am not gonna turn my world worrying about how other people keep their fish. Unless someone really wants to know a better way than they are doing it, I can't be bothered to waste my breath or my time with them. Go ahead rock your world enjoy it till it comes down on you like a tonne of bricks.
As for me I will keep on keeping on with my fishieworld the way I want to keep it.
Now if someone asks for opinion and really want's to learn better I am all for trying to teach them.
If not MEHHHHHHHHHHHHHHHH life is far to short to get hung up on the idiocy of another human being.
Another thing I can not be bothered to do is hunt out other peoples problem fish to "rescue" them, because I have found that many times it just ends up causing issue with my own tanks. That is unless it is a uncommon fish they for sure I will help you out by taking that to large fish off your hands FOR FREE that is after all I am rescuing it
