My female beta has dropsy . I have been using Epsom salt to reduce her swelling. I have heard that I should use Maracyn 2, but i cant find the medicine anywhere in stores or even online! I have an antibiotic called Clindamycin, but I don't know if it will work or is harmful for my beta. I also don't understand why my beta has dropsy. She is in a 10 gallon tank shared with 3 shrimp, ammonia and nitrates are 0, water temperature is 78 degrees F, and I have a filter in the tank as well. Could it be that fish today are not very healthy due to inbreeding and mass production?
