Just got a 3 month old male this weekend! Red Barred Ambilobe. I considered "rainbow" in another language, but I didn't find any that I liked. I've also considered Congo and Tropico. My veileds are Calypso & Calliope, plays off of the scientific name, Calyptratus.
Seeing a pic maybe helpful! Dont know if you searched for rainbow in italain but its arcobaleno (which is not only pretty to say but is in the masculine ) but being a red bar I'd like the name ferrari too. Sorry for the Italian theme, can't help it
