Hello all! I’ve posted on here quite a bit and so far I’ve really been thankful for the tips and advice that you all have been giving! Today I’m here with a confusing question. I had a betta fish but sadly he died from Dropsy. I still have the tank going, I haven’t turned off the filter or taken anything out. There are only live plants, a glass orb, and a hunk of driftwood. I’m considering getting another betta in the near future, do I need to toss the plants/driftwood/substrate? Or should I only need to change the water? Help!
