My wife saw a bunch of these schooling together at the lfs last night, and now really wants to buy 4-5 of them. We've got a tank we can put them in, but it's not a rift lake setup. Do these synos have to be in a high ph salted rift lake type setup like an african cichlid, or are they OK to be put into your standard 78-80 degree medium flow with good hiding spots type of tank? I don't want to buy them if the tank is unsuitable for them, so I'd like to confirm whether or not they need to be in a specific setup or not.
