Well. I was pretty disgusted at a Walmart today. Not only are they selling Pacus and Oscars and suggesting 10 gallon tanks for them, they have very tiny containers they are selling with built in dividers for 2 male Bettas. It cannot be anymore than a 3 cup water container. A lady was going to buy one and I talked her out of it as well as a bowl for a goldfish. The clerk told me I was driving away his business and I explained it is better in the long run for the fish and the owner. Well, when he left I happened to glance at the Bettas and saw 3 dead in the containers and a lonely little female looking at me. I promised myself I could not have another tank but had to bring her home. I ended up with the female betta and a 2.5 gallon. I brought a heater also for the tank. I know a 5 would have been better but really am out of room. So, she is in a tank with a snail for company. I did not cycle the tank. I hope this is okay. I added new gravel but used water from another tank as well as decor and plants. I am hoping she makes it through the cycle. What would you suggest for water changes during this time? I figured with the horrible conditions she was in before, this is the best I can do. I haven't named her yet, I want to check out her personality.
