Potamotrygon schröderi size and keeping info?

[Tor-Eriik]

I was wondering how big these rays really get, i see that MFK says 36" and Amazon rochen says 80, just like with motoro? How are these guys to keep? I have seen some threads around, and they should be kept at 28c, as they go inactive any lower. Pricetag pr individual for me is around 300-400$, ok price? If they get as huge as Tiger Rays i gues i have to go a second round with myselfe.

Same as a Tigger.

Do some diggin and there's pics somewhere of a huge Flower and Tigger being handfed. Appear to be like 36+" across.
