I've had my betta for just under two weeks now, and am amazed at how much stage presence he has! I originally named him Moe as a pun, but his name is now Mooch, for his personality.
He's about 2.5 cm from nose to base of tail, so I've been assuming he's pretty young.
This morning, I discovered that he's built a bubble nest, about 4 inches in diameter.
Awwww....my little guy is growing up and trolling for babes.
