My Whites Tree Frog (Kevin) passed last night.

This morning I noticed my Baja California Tree Frog (Trevor) seemed a bit sad.. like he knew Kevin wasn't coming back.. so now he needs a new friend.

I'm looking for a frog that will get along well with Trevor. Trevor is about an inch in length, so a frog around his size would be ideal.
I
live in Ventura County in Southern California. I am willing to have the frog shipped to me or if you live close.
