They don't breed as prolifically as RCS do but they will breed. As far as keeping goes it really depends on the grade. A higher grade usually means it been exposed to more in breeding for better color/markings. Which is why SSS+ is a lot harder to keep then A/S quality. Using distilled water is a great start as is covering up your intake. I recommend the Fluval Edge pre-filter for an intake cover. It's just a black sponge that slips over the intake. Gets the job done. Your going to want to keep the water really soft (I try and keep my tanks at a GH/KH of 2-3) at all times. They prefer temps of 72-74 which can be hard to maintain in the summer time but it's not the end of the world if it rises a few degrees. I would definitely try my hand at the lower grades before venturing into the higher grades. As a former reef keeper I'm sure you'll be fine but it's better to use caution at first then wasting a lot of $$$ up front. I'd recommend switching to a canister filter when you get the chance. Eheim 2211 would be perfect for a 10g. They just out perform the HoB's in every aspect. Plus you can use lily pipes and get an in-line heater to keep all of your equipment out of the tank and out of view. It's really worth it. Now if your going to be keeping live plants and using C02 just make sure to keep levels low enough so you don't gas your shrimp. Copper is a huge no no and will kill off your population so avoid it at all costs. Hope this helps.
