Fish myths

[Dubs1281]

Im sure we've all heard silly myths about fish and I wanted to post a thread to share them and maybe have people confirm/bust it.

I've heard that anything red is invisible to fish or just a shape, not detailed.
I think this is false because my cichlids can see my jewel cichlid.

Posted this elsewhere but I've seen external air pumps used (very briefly) as internal heaters. Also that it was ok to have water back-flow into the air pump. Can't think of the other one, will post if I remember.

Taking care of aquariums is easy.
I don't know how many times somebody has come to my house saying that they like my aquariums and saying that they might do it.
Then I tell them what my weekly schedule is and then it turns them off of the idea. And I have freshwater.
Props to all salt-waterers!

Fish do not require dark time, leaving the lights on 24/7 is ok because what's the point of having fish if you cannot see them. HAH

I know too many people that insist on keeping goldfish in bowls. They say why else is it called a goldfish bowl.

^this angers me like you would not believe

 

[bettaowner]

I've spent hours explaining to them why fish bowls are not suitable for any fish

You don't need to cycle a tank in anyway shape or form.
Betta's like to live in little cups.

 

[molliwopp]

Bettas should be given a filtered cycled tanks like any other fish. Keeping bettas in cups is cruel. In one my lfs they keep them for sale in little 1litre 20oz boxes and boy do they look unhealthy and miserable.

 

[molliwopp]

Which leads me to my next myth. A fish in cycle is as safe and fair as a fishless cycle.

•Tap water is perfectly fine for fish, there's no need for all that expensive crap like aquasafe and stuff.
• floating fish before putting them in is not needed and is a dumb waste of time
• I can put however many fish in as the tank can hold, I'll stop putting them in when I feel like it.

Goldfish only live for a few weeks. -_- morons

 

[molliwopp]

I read plenty of things where people thought they didnt need to preform water changes, thats up there with the best.

Is it bad if my betta lives in a heated, lit 2g? Do I need filtration? Because in the wild they live in stillwater, but, should I?

 

[twiddlemuffin]

Of course the all famous "fish grow to fit their tank".

Lol their the longest living fish!
Besides koi

Fish have an 8 second memory.

Changing your filter pad monthly is healthy for your tank.


People that like aquariums are crazy. (Thinking about it this might not actually be a myth)

 

[eduguy]

Don't change your water in a fish in cycle for a few weeks.

 

[Brookster123]

I'm certifiably crazy...
