How do I help my beta fish? He had red swollen eyes, raised scales, wont eat, trouble breathing, and won't really swim. I don't know how to help him. I changed his water and putt him in a smaller bowl for when he's sick but this is the first time.

Unfortunately, it appears as if he has dropsy. The pinecone appearance and swollen eyes are classic symptoms. This is not a disease but rather a symptom of larger illness. The swelling is caused by fluid retention caused by renal impairment, infection or failure. Dropsy has a high mortality rate, especially when pineconing is apparent. Treatment can be attempted using kanamycin and metronidazole. Both can be purchased from the local pet or fish store. Look in the aquarium section. Follow label directions carefully. An Epsom salt bath can help with fluid retention. Dissolve 1/4 to 1/2 teaspoon in a gallon of water and allow for a 30 minute swim once or twice daily. Remove him and place back in the hospital tank if he shows signs of stress. Daily water changes can be done to maintain water quality. Use only aged or conditioned water that is temperature matched to prevent further stress or shock.
