I was wondering if anyone had ever tried this before and what the results were. If you were to try it what species would you attempt it with?
It's been done many,many times, here are some tankmates I've seen it done with:
Koi,oscars, jewel cichlids,clown loaches,pictus catfish, various plecos,silver dollars,African aros,tiger barbs,green sunfish,bluegill.
Most can actually be kept with many non rift species, key is either high amount of fish or lots of hiding placesThe reason I ask is that I am not that interested in them except for some of the julidochromis and pseudotropheus species. I would rather add them to a community tank than setup a separate tank for just one fish.
Many fish can tolerate massive differences in hardness if acclimated properly , for example oscars and many s. And Central Americans do very well here, even tho our water is rock hardAren't a lot of those more softwater/ neutral water fish? I was thinking something like larger livebearers.
