Jack and Diane đ¶
Our Jack Dempseys are a breeding pairâif you look closely, youâll spot Mrs Dempsey tucked away in the rock cave. Both are a bit camera shy, but weâre getting there.
The Jack Dempsey fish (Rocio octofasciata) is named after Jack Dempsey because of its bold, aggressive nature and âready-to-fightâ attitude, much like the famous heavyweight champion. Known for being territorial, it will flare its gills and fins when threatened, almost like squaring up in a boxing ring, and can be quite dominant in a tank if not housed carefully. Despite its tough reputation, itâs also a striking fish with iridescent blue, green, and purple speckles, and even comes in a brighter Electric Blue variety. Native to the warm, slow-moving waters of Central America, itâs surprisingly intelligent too, often recognizing its owner over time.
