My beta recently started swelling. He is still as firey as ever continues to attack his reflection. Stays around the bottom of the tank like a healthy one does. I noticed the signs at first in the 10 gallon tank when he started to hug the water heater in the corner of the tank. I knew something wasnt right and continued to watch him. He didn't show signs for a month of anything wrong other than that. This week I noticed his belly was a little round but only seemed like I was over feeding him. However, as the week went the size the size doubled and is now truely dropsy. I feared it would happen since he is a 2 1/2 year old beta. I have put him into my medical tank its a 1/2 gallon and treating the water with maracyn two, Petsmart was out of beta fix. I know its not curable but at least it will lower the swelling and make his slow death easier.
His name is Shark for his blue body and bloody looking fins.
He is a very healthy beta despite the dropsy. :(
He didn't live alone in the 10 gallon tank I have a dwarf gormi, green catfish, and a juvinial angle. Despite the fact that dwarfs are suppose to be docile this one isn't he knew how to swim away from the beta and he shows aggression to the green catfish, and has marked dominance to one of the plants. The angle fish follows him around it's quite cute. I think it was the angle fish that taught him to swim away from the beta. They are both schooling fish so makes sense that they learn from each other.
