I have been keeping Betta for a few years now and was always saddened and surprised when they would die 1-6 months later. I didn't understand it, I was doing everything that my local pet store told me and they still died.
I'm trying now for the first time in about 6 months and based on all the helpful tips on the internet, this site included, I am trying for a long lasting companion. I was also surprised to find that most of the things that any local pet store would tell you are wrong (no surprise for most of you guys I suppose).
So I finally feel I'm doing it right. My new Betta Cobalt was well I guess rescued from my local pet store. I brought him home in a 2 cup tub and had a wonderful tank all ready for him. He has a place to hide when needed and a plant for resting. He also has a variety of food. I had some freeze dried blood worms left over from my last one, I picked up some pellets, flakes and some brine shrimp. He also has access to the frozen blood worms I had for my newt who died about 2 weeks ago.
He has a 3 gallon heated tank all to himself and a low/quiet filter that doesn't disrupt the water too much. I read up a lot of reviews about Betta caves and found that this Bonsai temple was enjoyed by many Betta and owners alike I also have a thermometer stuck to the side of the tank to monitor his temperature. And medicine on hand encase he gets sick.
Now that I am armed with the right knowledge and the right tools I am hoping for a happy health companion.
