I don't think that there are any members of the dasyatis genus that are actually freshwater

yes but we cannot duplicate the river... we can not keep there tanks from smelling like a over pissed in toilet and we dont have the means to keep them in freshwater basically... they can also swin back down the river to the ocean... they should be converted to salt and not kept fresh...


Joey its not worth it... will poison your beautiful Pbass tank :eek::cry:
 
I wish that freshwater raykeeping extended well beyond the Potamotrygonidae, but alas, it seems to only inch slightly beyond it. Even then, it never seems to get very far.

The Atlantic ray is euryhaline, which means it can travel into freshwater. It does so by increasing it's urine output tenfold to rid itself of water that penetrates it's body because of the osmotic pressure difference between the ray and fresh water. This does not mean that it is a Freshwater ray, only that it is found there. This is a rare occurence taht a euryhaline species would spend most of it's time in fresh water.
 
Yeah its not worth keeping, more than likely not going to survive too long witout the right conditions. Cool looking ray though.
