You can fast him for 3 days, but then feed bits of cooked and shelled green peas. This may help if Clyde is constipated. If the peas don't help, consider a broad spectrum dewormer or broad spectrum antibiotic. You can find both in the aquarium section of the local Petco. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.
