Well, with all my betta reading I've read about what to look for in a healthy betta but I'm having a hard time picking a new buddy. I had seen one about a week or so ago that really caught my eye. He was sort of green/turquoise. But yesterday I visited some pet stores and found it very hard to tell excatly what kind of shape they are in confined to those small containers. I got a real good look at a red betta at SuperPetz. They had theirs in a small plastic cup attached to the inside of a tropical fish tank. I tried to look at most of them but I got to one tank and found that the betta was swimming in the big tank and one of the small tropical fish was in the little container. It was actually the fist time I really got a chance to see a betta swim. He was in good shape fin wise and active in that big tank, but he just didn't grab at me. I stopped at the small pet shop close to home and they had their bettas in a little bigger container and wow, I saw some unusal colors. But most of these had very very ragged fins. There was a white or rosy colored one with red fins, very pretty however it was really red around the gills and I didn't know if that was because of the coloring or something was wrong. I was glad when I got home that I hadn't come home with anything because my tank water had dropped from 80 to 78 degrees. I am going out today to get a better heater. I had bought a 25 watt heater because it is a small 5 gallon tank. However, the only place I had for it on my counter is next to the french doors to our sunroom. Most of the time it's no problem but in the winter months the dogs like to lay out there before it really heats up so when they push the door open the cold air must have dropped the temp in the fish tank. So I am assuming the heater is just too small to do the job. I'll shop for a heater today and look around at some more bettas.
