Some silly stories about my veiltail boy, Rakki:
When Rakki was still in his 1-gallon bowl, he was obsessed with his thermometer. He loved swimming between the side of the bowl and the thermometer over and over again. When I moved him to his 5-gallon tank, he was very disappointed to discover that he couldn't fit between the thermometer and the wall of the tank anymore. It took him a few days before he quit trying and accepted it wasn't going to happen.
Speaking of the 5-gallon tank... some fish are freaked out being in larger spaces after being accustomed to smaller spaces, right? Rakki couldn't wait for me to let him out of the bag in which he acclimating to his new tank. He frantically swam back and forth at the bottom of the bag like, "Let me out! I must see everything!" He loves having so much space.
Most bettas make one bubble nest at a time, right? Rakki likes to make two: one near the back right corner where he sleeps, and one in the front right corner for everyone to see. He'll work a bit on one nest, then on the other, and goes back and forth between the two. I don't think he's happy with me messing them up when I do a water change because by the next day he's usually made a good start on rebuilding them.
He loved his first hide in his aquarium, a beehive that I got from Petsmart, and he was sad when I had to get rid of it because the paint was flaking. He's ignored everything I've tried to put in since other than a ZooMed betta log, which I had to get rid of because it was leeching junk into the water. PVC pipes? Nope. Terra cotta pot? Boring. I currently have a small porcelain flower pot in his tank as a hide, which he swam into exactly once, right after I put it in, and now ignores.
When I first put his dragon ornament into his tank, he spent 10 minutes circling it and flaring. It was so funny and cute to watch him trying to decide what the heck that thing was and why it was in his tank.
He couldn't care less about the ping pong ball I put in his tank sometimes, but he flips out over bookmarks left leaning against his tank. His favorite game is when my fiance wiggles his fingers back and forth across the front of the tank for Rakki to chase.
