Potamotrygon Histrix - A profile

[blackwolfXKAV]

Recently, in an lfs, I saw what ws only labeled as a "Yellow histrix ray". It might have been about 5-7" diameter for the body disc (not sure what the correct anatomical term is) with a tail perhaps half to a third as long as the body. Its coloration, though markedly variable, as with most rays, I've been told; resembled those pictures. It appeared active, and the owner said it had been eating for them, however, I have no intentions of purchaisng that ray due to the fact that this particular store is of...ill-repute..and the ray's tail did not appear to be in good health. The store wanted 79.99 US for it, though sadly they were not even able to tel me the min. size other than "you'll need a huge tank"

so, I did the right thing and did not purchase it. I went home and have since begun to reseacrh its requirements, however, I have not been able to find much.

Could you help me out here?

Thanks,

B.W.

thought hystrixs were smaller than that, about 13" max. give or take. anyhow, one thing i would add, is acuisition of these rays is usually because people want a smaller ray. make sure you identify it as a true hystrix, not the "peruvian hystrix" which will get a lot bigger.

does anyone have any ID info for the peruvian histrix, so I can ensure I know what I'm (possibly) buying?

Thanks.

now I'm kind of confused as well. I bought mine as a guyana. If you look at my link below there are lots of pictures of her. What is she?

She is not a histrix. Your ray has a faded color but, my guess is that she is an orbignyi.

i think Colin is right i had one and it was sold to me as a Guyana. mine had a Strong pattern appearance but unfortunately it only made it for about six months nice fish don't know much about them.

yea its a guyana also known as a humerosa/ orbignyi they are often confused the best way to tell the difference between the two is if the back feels rough, then its a humerosa

sorry guys for me it looks like a scobina ray.. i stand to be corrected of course

 

[turkeyboy85]

I dont think so.. i think its to light and doesnt have the pattern that the scobina does
