For your fancies youre going to want 30g for the first one and 10g for each additional - so for 6 youd want to have at least a 80g add the other fish and youre looking at 90+ gallons ... So if you want to keep all those fish you should look into getting a 90g aquarium.
The fancies can do fine with the danios. just maintain a temperature of 72-75 and they would all be fine. The temperature requirements for fancies and danios is actually not that far off. Fancies like 65-75 and the danios (zebra for instance) like 64-75; other species of danio like it a bit warmer than that low, but 75 would be more than adequate! I would think that minnows are for the most part cold water fish as well; and those similar temperature suggestions bear that out.
