Yes they are. I googled dropsy and my betta looks exactly like a picture of a betta with dropsy on that site. I am upset that the people at the pet store didn't offer me any real help with this. I have gotten more advice on here. Thanks to all who responded to my post. In the future I will know what signs to look for before it becomes too late if our new crowntail ever develops this symptom of an illness.
I know a lot of people will say, "Oh well it is just a fish..." My daughter is only 9yrs old and she has had for the most part sole responsibility of this betta, and has kept it alive for 3yrs. She won it at the very same pet store I went to for help at a Halloween event held there. She has done an excellent job of caring for the betta. In fact I've had bettas and haven't managed to keep them alive as long as she has with hers.
I will lower the water in the tank and add some salt to help make him more comfortable, but from reading the info on the dropsy site it is probably too late to try to treat with any medication, bercause at this late stage it would probably do more harm to the organs.
I'll keep you posted.
