How true is this ?

I was in a pet store yesterday and the guy said fish can't see red , is this true ?
I was going to buy a new net when I came across red ones , I asked the guy why they were so high in price $60. for a 6inch net is a bit out there.
well he came back with have you ever had a fish you just cant catch ,
well with these red nets you'll never have that problem again , he was trying so hard to sell me one of those nets , but I didn't bite , I figured he was pulling my leg for a quick sale,

I really would like to know if fish really cant see red .
it really could be nice to catch fish with out tearing a tank apart ,
and are these nets a new break through for the fish world ?
anyone have the answers

Most fish cannot see red light. The deepwater stoplight loosejaw produces red bioluminescence so it can hunt with an effectively invisible beam of light.

Don't spend extra for a red net. They make no difference whatsoever IME.

From a bass fisherman's standpoint. Red hooks and such were/are targeted to fisherman looking to insight a strike from the fish. It's said that red insights a feeding/attack response?? On the other hand it's said that they can't see red beyond a certain point of depth/light penetration. At any rate I wouldn't bother with the red net.. they'll either be able to see it pretty well or attack it..

As usual, it's not that simple.

They are sensitive to UV light for instance. And even if they couldn't see red, they would see the net as a shade of grey anyway.

Just because you can't see a color it doesn't mean you can't see an object.

I do know that viewing the reef under red light at night doesn't seem to scare the critters.

if I can find one for cheap maybe will try it , the $60. the pet shop wanted was just a little crazy, I have this one domino damsel I've been trying to catch for almost 6 months ,
I want to re-home him to my predator tank , he's just too mean for my reef tank ,
almost ready to just bait a hook to catch this bugger
I have been reading both positive and negative reviews on red nets been on Google
all morn reading up, so it sounds like it's either hit or miss
