Why Is My Blood Parrot Cichlid Lethargic?

A blood parrot cichlid that stops swimming is usually reacting to unstable or low water temperature (keep it a steady 25–32°C, with water-change swings under 0.5°C), poor water quality, fright, or low oxygen — they need more air than most fish, so run an air pump 1–2 hours a day. Hold the temperature steady, filter and change water on a sensible schedule, keep the tank quiet, and treat parasites and bacteria regularly to keep the fish active.
