Four months ago, I decided I'd like to have a betta to take to school with me. I went to the Petco in my town and bought a red crowntail. He was larger than the others and incredibly aggressive.
I named him Mr. Badfish because of his aggressive behavior (he was always flaring). I never thought I'd come to love this fish so much. Whenever I'd go to my tank to talk to him, he'd come, flare a bit, then calm down and follow my finger.
He had an incredibly large paunch in his stomach, and after researching more, I think he might have had dropsy or some sort of illness when I bought him. One side of his beard didn't extend either.
I'm not sure how he died. He was blowing bubble nests, though he wasn't eating. Thursday morning he was struggling in his tank and when I returned from class he was gone. :/
So, I'm new here but I'd just like to say some words for the little angry boy that brought me into this fish obsession. Today, I purchased Poseidon from the Petsmart near my school. (Also a red crowntail, but much smaller than Mr. Fish, and much less aggressive), so I'm hoping my experience with Mr. Fish and my growing betta obsession will help Poseidon (who seems healthier than Mr. Fish had been) live a long, happy life.
This was taken a week before his death. You can see bubbles near the surface. This tank had a yellow background.
