When choosing a healthy specimen, pay attention to the fish's activity: in the store, it may hide, but upon inspection, it should show cautious curiosity. The body should be clean, without visible wounds, white spots, ulcers, or signs of fungus. Avoid specimens with sunken bellies, which may indicate emaciation or internal parasites, and with unnaturally bloated bellies. Make sure the fins are intact and the eyes are clear and transparent. Since the species is often imported, it is advisable to ask the seller about the fish's adaptation period to aquarium conditions, as recently arrived specimens are subject to severe stress.
