hystrix owners-----or just ray owners...

As mentioned before about the lack of vegetation, you could always get some ghost shrimp and gut load them with algae waffers and other greens.

but the thing that gets me about that is, who else has hystrix that are feeding the same thing as me. i am sure they are a few.

I feel it may have to do with your water. I try to keep my stingrays off saltwater foods and on nutritious gut-loaded inverts. My bet would be your water.

Did you have a picture of it? If this is something with a quick onset, I might tend to think it was from something recent (like water quality),

I agree..

as opposed to something that would happen more long term(like a nutritional component).

Could this 'long term' duration be shortened by the fact that they are very young juvenile rays with an accelerated need for nutrition due to their rapidly growing body... ?

Note that the raykeeper said this happens about a month after being in captivity, and it happens to all of them, but not any of the other rays, except the pregnant one. The pregnant one could be having a hard time with nutrition due to carrying pups.

These were just commonalities that I found.. and some of the reading I did about nutrition deficiency and cloudy eye said it could be caused from lack of a specific needed nutrient... one of which might be found in the native habitat, but not re-creatable in captivity?

I would agree with what some have said that a rapid pH change could cause a problem. If it looks more like a cataract I might lean towards nutritional,

I agree with the cataract.. I would imagine a 'film' over the eyes from bacterial or water quality would look different then a 'foggy' inner area of the eye from nutrition or blindness. Good Point.

but there are so many possibilities that it is not really possible to diagnose via the internet.

x3 agree...

Possible need for vitamin supplementation?

i actually have high ph..

Have you tested your GH and KH yet? If too low, your pH could be crashing within hours of w/c's despite a high initial pH our of tap.

i was too busy this weekend to test it.... i need to get on that.


like i have said before the eyes look glazed...almost scratched. the 2 smaller ones seem to be worse that the 6"er. i have pictures somewhere..i will post them up.

also to Miles's comment: the pregnant female motoro's eyes are slightly cloudy, not the same as the hystrix.
THe Hystrix's eyes are muchy worse it starts off like ick on the eye ball almost, small white crystals oround the perimeter of the eye, then fills the entire eye.

one of my ray had this problem, and it recovered from using maracyn 2

My water is very hard from the tap, hardwater stain every where in the kitchen and stuff. not sure if this helps, but i had that white film covering the eye for awhile

i have binox at hom but scared to use it... seems like it damages the bacteria.
