RANA PEREZI or southern marsh frog found through out the Iberian peninsula, I saw some in a fountain in the very center of Albufuara once way back in the early 1980's. t could have been reclassified since then though.
It's been renamed Pelophylax perezi; can see description in link provided on my previous post (no. 2).
Remember to take care of the enclosure and it will take care of your frog !
