Cold water causes parasite problems
Chilodonella is known to infest fish that are exposed to temperature dips. Reduce the chances of this parasite attacking your fish by using a high-quality aquarium heater. A stable water temperature will keep the fish's immune system working and fighting off Chilodonella infestations..
