L25s are a species of giant bottom-dwelling fish that tend to be shy and introverted. To make them feel comfortable, it is important to provide low lighting or darkness and a cave where they can retreat and feel secure. Despite their size, they are not aggressive towards other bottom dwellers and are happy to share their space with them. However, they are territorial and aggressive towards their own species, and fights can be violent and detrimental due to their size and strength. It is recommended to provide clearly separated spaces for each fish in the tank to minimize the need for them to look for food outside of their designated area. Over time, they may get used to each other's presence and learn to live harmoniously, but it is crucial to monitor their behavior and intervene if necessary to prevent injury or harm.
