Awwh, I love this thread. Everyone's fish sound so cute! =']
My female veiltail, Ann, is SO energetic. She seems to like patrolling her tank, chasing her reflection, and gets really excited and shows off when someone comes into the room. If someone puts a finger near the glass, she'll chase it around. If they stay long enough, often she'll beg for food and swim around looking for some on the surface. She has a little cave that she'll swim into and then swim circles around. When she finally gets tired out from all of this, she finds a place on one of her plants to rest. Even that is super-cute. Never a dull moment!
I'm never bored or lonely in my room because she's just so active and seems to genuinely enjoy her life. :-D
