Dumbest Aquarium advice you've ever been given?
 

Goldfish like dirty water, you really dont need to change it.

Corys like being alone & don't do well in groups

If you have a Pleco you don't need to gravel vac or do water changes

You can & should leave your lights on all the time

That's horrible, so I guess they would like to live in a house filled with their rotting left over food and waste!

Its sad my bestfriends dad gave me that advice. And my tap water has super high nitrates so once a week I go over there and lug 15 one gallon jugs home with me. He looks at me like I'm an idiot.

This common pleco will do just fine in a 10g tank.

It has gotten to the point where I ask them questions I already know the answer to. One reason is for shiggles. The other is to determine if I will buy fish there... ever.

I got told this, goldfish are dumb, they have a three second memory span, if you don't feed him, he will forget about it, if you keep him in a bowl and he is the size of a fist, he won't care because of their short memory span, just do your weekly water changes, it's so dumb it doesn't even make sense

A oscar will go good in a 20 gal ~[store]~

That pleco thing is very dumb

So it's ok to keep a fish that is longer than the tank, what's up with that!

I guess he's the dumb one
