My cory can't swim anywhere in the tank without doing a barrel roll so I think he has a SBD. What is the suggested course of treatment? I heard to try and give him a slightly cooked pea as that will help with any constipation he might have. One of my danios looked like she may have been pregnant but her erratic behavior today caused me to isolate her fearing it may be dropsy. Could a bacterial infection from the danio possibly infected the cory and given him the disorder? Should I quarintine the cory? I know the SBD itself is not contagious but whatever gave it to him may, although it looks like much of SBDs are attributed to either defects or diet/constipation? Any suggestions?
