I have a fuzzy dwarf and he will eat silversides mysis and krill all frozen - not that hard to train them either, hunger is a wonderful motivator. I'd stay away from the lions at big als here in calgary unless you are putting it in a 4 foot or longer tank, they are not the dwarf variety. Golds may be ordering some shortly as I told Dennis tht I need a second one. Also for the dwarfs I would recomend the fuzzy over the zebra as the zebra hids more, also dont expect to see them for a few days till they calm down after being moved - they hid when stressed and also when they are full.
They dont bite persay but if you get stuck by the dorsal spines - venom location on the dwarfs - the pain is approx. three times as bad as a bee sting and there is a possibility or an allegic reaction.
Here's a good link for general info:

Personally I would recommend one, theyacn be quite entertaining.
If you interested feeding day will be Mon or Tues - stop by.
