I have a 200L tank with rosy barb, minnows and shrimp My local shop said they would all be happy if I made my tank tropical I have been thinking about it, it came with a heater Is looking after a tropical tank just the same, same amount of water changes etc? I am thinking neons would look nice with the fish I already have
You can, but you need to acclimatise them slowly. Dint ramp up the temperature too fast. I'd aim to raise the temperature over a week or two and try to find the overlap of acceptable temperatures and keep it in the sweet spot.
