AMMONIA POISONING
ammonia poisoning: translation
ammonia may build up in aquaria from fish wastes, decaying food and plant material and poison fish. Symptoms are gasping, excess mucus production, reddening skin from capillary haemorrhages, erratic behaviour. An efficient biological filtration system prevents this condition but if it does arise fish need to be moved to a mature aquarium where the nitrogen cycle, q.v., is in full operation
