My melanoid is name Sonriente, Spanish for 'Smiley', as 'lotls look like they are always smiling!
Then there is my leucistic Tenedor, Spanish for 'fork'. She has a lovely fork in her middle left gill stalk, name stuck quite well.
Banana is my golden albino - he was my very first axie, given to me for Christmas from my sister! Was very surprised to receive him.. I had been planning on getting axies for the past few months. Luckily I keep fish, so had a spare cycled tank for him (no fish in it), while his 400L (105.6Gallon) tank was cycling. Long and yellow... the name Banana came to mind.
I've also had a Bastante, Spanish for pretty.. and an Aristotle Axolotl, my friend thought of that name.
