Here's the deal. I recently had to get rid of all my animals because we had to move suddenly. So the only thing I can have is a fish. Well last night I took a trip to my local Wal Mart (Big Mistake I'm thinking). I sat there debating on what tank size to get. I debated between a 2.5 Gallon tank for $25 and a Betta-Tech bowl for $13. Well I decided to go cheap and I went with the Betta-Tech bowl. Well I also bought a Betta there. Yes I checked to make sure there was no sign of fin rot and good colorization all that stuff. Well we got home last night. I sat up the bowl. I had used some distilled water that we had bought earlier that was already at room temperature. Well I put him in there, and I woke up this morning to find him dead. I think I did something wrong. I don't know what I did wrong, but I must have done something wrong. After reading all of the posts here. I think I'm gonna go back and buy the 2.5 gallon tank then I'm going to the local pet shop and buying a better quality betta there. I just want to know what I did wrong, and If there's any advice you could give me for my next purchase.
