When I went to college, I had a hard time adjusting. I only had a few friends and stayed in my apartment bored, but when my mother gave me my male betta fish to liven up my apartment, things got better.
He was a blue, crowntail betta who was very smart and entertaining. I named him after a popular Biblical figure and I kept him in a Betta bowl with a water conditioner, fed him twice a day, changed the water regularly and got him a leaf hammock.
When I went home for the holidays, I would transport my betta in a little cup and take him with me on the train, then when I got home I'd put him in a spare bowl that I had.
It seems silly, but I really got attached to the little guy. He would swim back and forth and whenever I came up to his bowl, he would swim to the glass and look at me. He'd follow my finger back and forth and he made beautiful bubble nests.
I had him for 2 years before he died at my parents house over a Thanksgiving break.
RIP to my little college buddy. My first ever Betta fish and a truly unique fish!
