Ok, you've managed to get me confused: The subect title is Euotropiellus buffei, which is a synonym for
.
However, you also say "African glass catfish", which is another member of the same family, but not the same genus:
So, which one of these do you actually mean?
As to compatibility, you've already covered the fact that they are diferent pH. Both catfish species are river fish, which means that they will like flowing water, and they prefer softer water.
Both the Neolamprologus and Julidochromis species are Lake Tanganyika fish, and they prefer higher pH and fairly high hardness.
I think you can compromise between the two ideal conditions, but the tank will essentially end up having fish from two different habitats that both aren't in the best possible conditions.
Further, I would worry that the c-ichlids are agressive towards the catfish, and that there's not such agressive species in the catfish's normal habitat, so they are defenceless for these attacks - generally fish from the same habitat will cope with each other, at least as long as they are reasonably the same size. This is just speculation, as I've never kept any of the species involved in this discussion - one of my childhood friends parents had a Julidochromis pair, and they were litteraly unable to keep any other fish in that tank...
My personal suggestion would be to set the tank up for Tanganyika conditions, or something close to it, and get one of the Tanganyika Synodontis species.
