Relevant Information:

Aquarium Care: This species is the exact opposite of the beautifully marked L. oncinus, and in the aquarium, just like its congener you may not see too much of it as it can be crepuscular in nature and will need hiding places to make it feel more secure and happy in its surroundings. Can be kept in a community tank but may eat very small fish at night such as the fry of livebearers, but basically a good addition to the larger tank set up. My speciman is kept in a 48" x 18" x18" with a large Synodontis nigrita and a Pike Cichlid, so it has plenty of room. I don't see it very often, only If I am rearanging the tank layout. Can be territorial with its own kind but you can get round this by providing extra cover such as pipes and driftwood. Can tend to change its body colour from dark to light according to the substrate. Diet: Will take most prepared foods such as frozen bloodworm, tablet and flake food. Better to feed at night after lights out, but once settled in tank will forage for food in low light conditions.
