Well I'm at least happy that I have Espen! He is soooo small (compared to Spooky and BT, they are at least two, three inches without the caudal fin), maybe an inch and a half without caudal. He's also clearly a brat. He's already sneaking into gaps I didn't realize were there and has claimed two thirds of the 20g as his own.
I mustache you a question
