[Whitecloud Minnow Water Hardness]

Anyone have any parameters for Whitecloud minnow water hardness? I am currently running 15-18 GH and 15-18KH. Should I dilute with distilled water or is this range acceptable?

[Whitecloud Tank Temp.]

I have read whiteclouds do best below 72 F. My tank currently ranges from 73-76 because it is winter and the room is heated. I have tried to cool the tank with little success. Is this temperature range acceptable? Or do I need to look into more cooling systems?

[Whitecloud Feeding]

I am wondering what to feed my whiteclouds? Are tropical flakes okay even though they are cold water fish? I currently have been feeding extreme krill flakes with some freeze dried bloodworms/ brine shrimp. Does this sound good or can I improve?
