Hello, today after I've identified yet another betta with dropsy I asked myself a question. Can I even properly care for bettas? But, I'll give you guys a backstory and my circumstances so you guys can give the best answer possible. Okay, I keep all types of freshwater species of all shapes and sizes, plecos, loaches, the aquatic frogs, cichlids, sunfish, tetras, guppies, and many more. Some I keep are even advanced to keep. A green spotted puffer (yes he's in a brackish tank) for example. Also, parachromis. Plus others too. These fish aren't easy to keep if you didn't know, and the worse case of any sickness besides bettas was when I got calamanus worms in a community. Keeping in mind all of this, and that I do weekly water changes, feeding variety, etc I do for my bettas I wonder why they all have gotten dropsy. I take as good care of them and watch parameters as much as any other tanks I have. But for this betta, should I euthanize him? Those are my 2 questions. Cheers in advance.
