Usually it's a good rule to go by to put naturals (like your Drindian, Zenirix, and Otachie) for ten thousand tu, at the least. It requires a little more patience for someone to happen by and like your pets even at the higher price, but at least when you do sell them they go for a decent amount. Lower isn't necessarily better.
I'd personally value Destrone the highest out of those three, followed by Jasmyn and then Eccentrico.
The lowest albino Chimby on the search is at five million tu, so you should go with a price a little higher than that. I'd say around seven; Ruuze is a pretty nice name.
