Cool, thanks.
Does any type of sand help buffer the pH or does it need to specifically be crushed coral. I have play sand in my tank with MTS to aerate it for me, but if I were to convert to a shell dwelling cichild tank would all of my trumpet snails be eaten? I know that in general cichlids eat snails, but I can't seem to find a concrete answer online if the smaller 'shellies' will or not. If I do eventually go the route of these cichlids is having snails to aerate the sand even a concern of mine or will the fish mix up the sand enough to prevent any problems?
Also, what's the most colorful breed of shell dweller out there? I've googled a little bit but can't really seem to find that great of pictures...
It doesn't need to be like raw crushed coral, there's a product called Argonite that is basically like crushed coral and raises the pH but it comes in a number of grain sizes. There's a specific one for cichlids which I have mixed in with white silica sand in my 65 gallon tang tank. I would think that MTS would survive and continue to have a population, the shellies would probably just push them out of the way if they came close: I'm actually not sure shell dwellers would eat them, my guess would be no .. and to answer the second part of question, yeah your shell dwellers, especially if you were to get Multifasciatus they would be moving the sand around constantly.
There are a good number of shell dweller species available. many of the Lamprologus species are colorful, one in particular being Ocellatus 'gold'. Some of the Neolamprologus species are exceptional as well; like Brevis, Multifasciatus as I mentioned earlier, and there's Caudopunctatus also known as 'punks' which have like a yellow band on their dorsal fin they're pretty cool.
I've been planning on getting shell dwellers for a Tanganyika tank for about 6 months and it looks like this week I might actually be getting my fish so I pumped lol. I haven't fully decided which one I want yet but a portion of the tank is also rocky which I'm going to give to a species of Julidochromis. I was a little surprised to see this thread cause I hadn't heard anyone talk about them till now. And like OC was kind of saying, yeah don't put fish that don't belong in lake Tanganyika in with shell dwellers. It just doesn't make sense to me, I believe tangs should stick with the tangs. Their environment is truly unique and their requirements are different from that of the fish mentioned earlier. Let this video Inspire you;
