| Habitat and Ecology: | J. merlieri do venture into the open, but never far from the rock cover. Breed in crevices and caves. The behaviour of the fry is not standardized. Sometimes they are spread outside of the cave as soon as they are 15 mm long. When threatened, they do not hide in the nearby breeding cave but flee along the boulder wall. At other times the fry remain inside of the cave and apparently do not venture out until they are much larger. |
| Systems: | Freshwater |
| Major Threat(s): | Water pollution; sedimentation; land agriculture around the lake; fishing activities; over exploitation for aquarium trade – since its first exportation in 1971 it has reached worldwide popularity among aquarists. |
| Conservation Actions: | There are no conservation measures in place for this species. |
