Gots a question

[robertmathern]

Most all of us have herd that most marine animals cant really see the color red. Thats why we can use red lenses or a flashlight to look at our tanks at night with out bothering anything in the tank. Well Riddle me this batman if that is true then when my false perc was alive (RIP little guy) Why was it when I pointed a red laser on my rocks he would attack it? Just trying to figure it out since I have had a few drinks now I want to know. Or was my clown just in a class of its own when it came to being mean?

This is just my own opinion, some fish do see red light hence the use of red fishing lures as well as the fact that fish are basically carnivores and the sight of blood stimulates their attack mode . I think critters that live in deeper water may not be able to perceive red as that color does not penetrate the water at depths so they have no receptors for that color.
BTW what were you drinking?

No answer; but if fish can't see red, why would so many fish have developed such stunning red color? Red is also a favorite color for tarpon flies, billfish teasers in many areas, and my favorite bonefish fly pattern is mostly red.

Laser's intensity is hundreds time stonger than regular light by being focused. You don't see algae cells, but you sure see hair algae killing your corals; same principle.

My SW fish could care less about the lazer pointer (even my false perc) but I know they can tell it's there. But when I point it into my cichlid tank...they go stupid crazy trying to kill it and eat it.

lol nice it the difference between a regular and a laser that make the difference. regular light with a red lens will not really penetrate the water but will light it up. The laser will put a beam in it that the fish will see. The big part of the question is since the red light dont penetrate the water that well the fish and others will not see a shadow of a preditator and not hide

Watch where this thread goes. in a month or so, someone will say that they read that laser lights cure ich or eliminate nitrate.

I once took 3 laser pointers, red, green, and blue. I beamed it into my protein skimmer, and after 3 months or so, my nitrates, and phosphates were not detectable. I stopped making water changes, was over feeding, and still no changes. The corals started to glow more in the actinics, and all my hair algae was gone. So i continued for months without water changes, and added few more pointers, this time they were wind powered to stay eco friendly. I took my refugium out since the macro died anyways and now I don't even run a filter. Just the skimmer and 8 laser pointers. But i added a new fish, and you guessed it, it had ich. So with a regular treatmeant of fish with the laser ich removal, btw, they loved it, I eliminated ich. Please, email me for the address where to send the free hair algae frag.

Somebody will try that.
