There's very little info online about them but from what I have gotten back from exporters is that they are collected from shellbeds. In my own tank there is a lot of rock work and very little shells so they have stuck to the rocks mostly but I have found females that would retreat to the crevices/holes found in some of the rocks.
With the addition of the brevis and some Neothauma shells they have slowly moved their territory to the shells but they are in the water column more often in comparison to other shellies.
I did find one article I think by one of the friends of AdKonigs that there was a report of these cross breeding with a buescheri so it's not definite and possibility they are not particular.
quick shot with my phone of my new Dwarf Giraffe cat that I added to the tank. Didn't have time for a nice shot and had to use a flashlight to spotlight it some.
I let the females brood their own young, most make it and natural selection takes care of the rest. I use to attempt 100% fry survival when they were in a smaller tank but since being housed in this one I just leave them be. Only the strong survive and there's a ton of babies swarming around.
Since it's a pita to net anything out of this tanks I have been exploring my options of adding a predator to snap up a few fry here and there. There are plans for a tanganyikan elipsifer soon and whatever else I can find along the way.
