cherry shrimp and UV

has anyone exposed their cherry shrimp to high levels of UV? I ask because I have a tank with cherry shrimp on which I put some high UV producing lights. no, I don't know the exact amount and intensity of the UV, but I do know it has UV since It elicits the alexandrite affect quite well.

anyway, the shrimp have colored up quite a bit in the last month. it makes sense that the shrimp would produce more pigment in response to the UV, but I don't want to miss the Forrest fort the trees so to speak, so I'm asking for the experience of others. has anyone else tried this?

I don't think anyone has actually shone a UV light directly into the aquarium containing fish/shrimp before...

Some people run a UV light inline to kill parasites, free floating algae, etc and this has no harm on shrimp.

Also, from what I have gathered, the Alexandrite effect is due to visible light, not UV light.

well, my synthetic alexandrite fluoresces under UV in a color it never shows without, so my lights produce UV. i can get a few other things to fluoresce as well. as for the color change, i double checked and your right. i read something different a while ago, but it wasn't from anything authoritative.

i really meant fluorescence, but my brain wasnt working very well and i just happened to be holding a piece of synthetic alexandrite...

anyway, i was just curious. i guess what i need to do now is find someone who has been breeding shrimp, trade for or buy their less colorful ones, and send them back to them later to see how their culls rank in comparison to their choice breeders. it would be cool if this works well.

i guess i should also set up a control tank...

I know a few people that have heard from Asian breeders who use UV bulbs, like the reptile style that give UVA/B over their shrimp tanks claiming it helps the shells or something. As with anything in the shrimp hobby, there is someone doing whatever you can think of, some claiming it works, some saying, no you have to do it this way because so and so does.

In the end, it's not going to hurt them in anyway and may or may not help with any benefits to the shrimp. I would say probably not though, as most UV bulbs don't penetrate the water beyond the first few inches. This I know from tests I've seen people do when I was keeping turtles and testing things like that for UVB bulbs and basically saying they have to be over the dry/basking area or else their useless to the turtle under water past the first couple of inches.

uv light is not good for living things....go lay out in the sun for a few hours and see if you get sun burnt. strong uv lights can mess up your eyes to. that said i would think the water would weaken the uv a lot

Long exposure to Uv light isn't good. It's needed by our bodies for Vitamin production, specifically Vitamin D and has many benefits to the human body. In 10 hours of sunlight you will burn. In 20 minutes, your body has already started making Vitamin D, so I disagree with your statement.

Your analogy is like saying bleach is bad because if you drink 5 gallons of it, you will probably die. Yet in small does in our water, chlorine is one of the single biggest thing that has saved lives by stopping water born bacteria from killing us off. One screw up of not managing enough chlorine in the water caused 7 people to die and 2500 to get sick from e.coli in Walkerton, ON about 10 years back.

i will admit, i do not believe that the UV is GOOD for my shrimp, and could possibly harm them in the long run. im too much of a curious bastard to not try it though. once i get a "what if" question in my head, im compulsive about answering it.

UV can be completely blocked within the first few centimeters of water or it can penetrate many meters into the water. it all depends on what you have in the water that can reflect or absorb it. if you have dark stained water rich in tannins, forget about getting UV into your tank. if you only have dissolved salts though, you can probably get UV to penetrate deep.

the bottom of my tank still makes fluorescent objects light up, so im pretty sure the UV is reaching the bottom of the tank. even if it didnt, a lot of my shrimp spend a lot of time up near the surface anyway.

it may make no difference, but who knows? we wont discover new ideas without trying new things. ill have to play it out and see.

i can tell you this though, i had a group of fifteen amano shrimp in another tank for a couple months that never showed any color, but after a couple weeks in the UV tank, they are showing color and patterns. i need to set up a control before i can say that it is the UV that caused it. dont want to get ahead of myself.

In nature they would get full natural UV, way more than anything a bulb puts outs and it doesn't effect them. What type of UV are you using? You haven't specified that, as that would help determine how much it is penetrating.

Also, they may look brighter or more colorful under the UV light but have you turned the UV off to see if the color changes you are seeing are the actual shrimp or just the color of the visible part of the bulb.

If I have a tank of clear ghost shrimp and use blue and antic lights and they will look like purple or blue shrimp but doesn't change the fact they are clear.

i moved one of the mediocre shrimp out and this is what it looked like. it was mostly transparent a little over a month ago... wish i had the first pic for comparison...
this was taken in the UV tank.


they actually look brighter in my other tanks. all the blue kinda leaves them looking washed out in the UV tank.

The problem with your experiment so far is that Cherries tend to color up as they age. Tough to say if UV had any impact.

Maybe you could test things out on other varieties of shrimp?

+1 to what Jake said. I've take cherries out thinking they were bad looking and put them in a community tank, only to have them hit that magic age and color up nicely, so just because 1 colored up, it's hard to say.

i wouldnt say i have an experiment going... yet. it doesnt qualify as an experiment, just a casual observation. when i split one tank down the middle with a divider that blocks light, and set up two different kinds of light on it... then we can start calling it an experiment.

ill try and get a pic of some of the younger ones. the person who sent me these shrimp was showing off one of her more colorful ones and it doesnt look as bright or solid as this one. she was surprised at how mine look. it could just as easily be the food though.

What kind of UV light are you using?

Experiments are hard like this, because you can take two babies from the same parents and one will look awesome and one turn out like crap and that's just genetics and the reason we cull so much, so it would hard to attribute it to the light.

i cant remember the brand of the light strip, but the bulbs are 3 seaworld t5ho 12000k and 3 seaworld t5ho actinics. i dont have a clue how those lights rank against other brands, i just know they produce some nice UV. i could go with better known lights, but i like testing new things and im getting a par meter soon enough, so ill be able to find out how they are with par. in the meantime, my wife just tracked the company down. they are based in

this whole tank is testing new stuff, new ideas, new way of doing things.

but don't worry, if i set up a tank to test this idea, it will be set up as a true experiment. identical growing conditions save for the type of light. they will even share the same water and will just be separated.
