The Panamanian Oyster Blenny (Hypleurochilus pseudoaequipinnis) is a small, hardy marine fish that typically grows up to 2-3 inches in length. This blenny thrives in a well-established saltwater aquarium with plenty of live rock, which provides both shelter and foraging opportunities. It primarily feeds on a diet of small invertebrates, algae, and detritus, so offering a varied diet including live or frozen foods like brine shrimp, mysis shrimp, and finely chopped marine algae will help keep it healthy. This species is peaceful and does well in a community tank with other non-aggressive fish, but it's important to maintain stable water parameters with regular water changes to ensure its well-being.
