Known as the kiss of death to all pond lovers my comet has recently succumbed to dropsy. I've been treating my fish with tetracycline as reccomended in DrDave's thread, but it has yet to show any significant results. As of now my fish is still swimming quite normally, but I'm concerned with the effectiveness of tetracycline because it has yet to work. Does anyone else have suggestions for me? Also I've been doing 50% water changes for about 3 days now.
