Poropanchax is indeed their new name. It was changed a few years back, only spilauchen remains under the genus Aplocheilicthys. Congopanchax was also changed and is now under Poropanchax.
If I am not mistaken, macropthalmus is now luxopthalmus, so that name is no longer valid too! I say these scientists need to go out and collect new fish so they can leave the ones with established names alone.
I currently keep 7 species of Lampeyes and all the tanks are open top and have no problems of them jumping. If you give esch fish enough space, you'll get less aggression resulting in happy animals that do not make the leap of death. These are a great group of fish that need more attention in regards to planted tanks and the hobby in general.
