ever play follow the leader with your fish?

[moose1960]

I went and bought one of those lazer pointers today, for a teaching aid, when i just had to see what the fish would do if i shone it in the tank. Much to my surprise they all started to attack and chase it. Funny watching 6 specic of fish chasing a little red dot.:D
Wonder if other colors would do the same.
Cats chase it, dogs chase it, kids chase it, and fish chase it.
Great minds must think alike ...lol

careful with that lazer bud....you could more damage then fun....like stressing them out because they think thier territory is being invaded.....also catching one of them in the eye could do a world of stress.....but i have played follow the leader with my finger tip on the glass with 3 black angelfish.They would follow my finger and line up at the top of the tank where i would drop little flakes in thier mouth for feeding...i miss those fish.....ah well:(

I know Kittens LOVE those lazer pointers! Also tourists at disney world.

Hey, Arctic_Fishery and anyone else out there can you talk to me more about your opinions on lasers..... I have just ordered a Miracle Beam combo Laser and Hi-Lite backlighting system...

There web site raves of the benefits of lasers for raising fry, help reduce bacteria, etc. etc. and FISHZINE magazine did a big product review on it too....

Are these lasers really dangerous??? If so, when my shipment arrives tomorrow..... what'l I do.....:confused: :confused:

[Arctic_Fishery]

hopefully other people can help you bud...cuz my knowledge does not fall in that area.....sorry.you should ask that question in another area as a solo topic....

Ever play, lets see if you can bite my finger off with a RD? Its pretty scary, LOL. I love my RD hes soo cool!

He also follows my finger around the tank but I dare not to use a laser pointer (mostly because I dont own one, LOL) and secondly because it may not be good for the fish as previously mentioned. Darn, fish are so fragile, huh?

Serrateeth if fish couldn't see red, there wouldn't be any red-bellied male sticklebacks.

Long ago someone told you that deep sea fish and other critters are often red because red light penetrates least well in water, so at depth red fishes appear black.

Don't you think that was it?


...whatever...

Fish cannot see red. That why people use "red lights" to see their nocturnal fish at night. If the fish could see the red spectrum, the nocturnal fish would not come out.

I have a red pointer laser, too, for my psycho cat who will climb the walls trying to chase afer it. It's hard to keep your finger on the button when you're laughing so hard! :D
Anyway, I shined it into the tanks once and sure enough, the fishes took chase. They all tried to eat and catch it....

So, if they can't see red, how could this be....?

dont know? I know when I asked about seeing nocturnal fish at night, people always suggested having a red light because they cant see red light. So i dont know?

Birds, fish and many other mammals perceive the full spectrum. Some insects, especially bees, can see ultraviolet colors invisible to the human eye. In fact, color camouflage, one of nature's favorite survival mechanisms, depends on the ability of the predator to distinguish colors. The predator is expected to be fooled by the color matching of the prey. Until recently, it was thought that dogs didn't see any color at all. Recent studies now show, however, that dogs can differentiate between red and blue and can even pick out subtle differences in shades of blue and violet.

This is a link I pulled up with a google search, the text above it is from that link. True? I don't know.

What I do know is that my fish swim away when I shine a red-lensed flashlight at them, but not as fast as they do when I use a normal "white" flashlight. They can see the red light, it's just not as harsh to them IMO. Wetman brings up a good point as well...some species use red to "display" during courtship, why would they do this if it wouldn't be seen?

If you can show me otherwise, I would like to see it. I've always been curious about this, so prove me wrong!

They have red colouring doesn't mean they can see red,octopus see black and white yet the can change into that exact colour except for 2 different colours of the same intensity,fish should be the same,that's why dogs can differentiate red and blue,probably because intensity were different
