I have had 3 betta fish in the past before and it never occurred to me to research them (unfortunately). After my third betta fish died, I didn't find myself wanting another one until now. Having several other pets, I have learned that pet keeping is never as simple as one thinks. So I began researching. I found this forum and was really impressed with all of the information and advice I found. I find that personal experience is far better than commercial as stores will advertise living conditions that I wouldn't even put a shrimp in! I bought a crown tailed betta from Walmart as my Petsmart wasn't selling any. Unfortunately, now I believe that I bought an unhealthy fish. Dante stays at the bottom a lot (much like my second fish when he was about to die) and has trouble reaching the surface. I am not personally happy that I have to do this, but I put him in a bowl as it made it easier for him to reach the surface. I have been trying to find other ways to help him but I don't have much hope. However, I refuse to return him to walmart. I have heard that it is part of their policy to flush returned fish down the toilet, even if they're alive! I couldn't risk that. Anyways, I so happened to be at Petco, looking at fish supplies and I saw their betta selection! They had gorgeous fish! I have never seen such a variety of betta fish! I saw a halfmoon that I liked, but he was way too expensive. Then I saw a Delta tail betta that looked similar to him and seemed very lively. Perhaps it wasn't prudent, but I bought him. The picture doesn't do him justice. Flash was the only setting that allowed me to capture his colors as closely as possible. I just love him!
Here he (still thinking of a name) is in the store cup before I was going to begin acclimating him to the tank water:
