It has to be so much fun! I'd love to try that

After all ... what can be better than sun, the only natural light there is?

Also, constant availability of fresh air probably also plays a big role. Only I don't think I could do that with the temperatures we get here, and with how suddenly the temperature where I live can drop at night. During the day it can reach 85-90F but feels like 95-100F because of humidity. Then at night .... while it is still humid and hot, the temperature drops dramatically, as there is no sun to warm up the air and the ground. Here is a typical summer week in NYC:
Friday: 89F day, 72F night
Saturday: 87F day, 69F night
Sunday: 91F day, 72F night
Monday: 97F day, 76F night
Tuesday: 98F day, 73F night
Wednesday: 92F day, 74F night
Thursday: 92F day, 73F night
All of the above are only in terms of temperature, EXCLUDING humidity. Humidity makes it feel 5-10 degrees hotter than it actually is. This particular week is pretty stable, but beginning next Saturday it will be 84F day and 69F night - a rather sudden transition from Thursday which is 92F day, 73F night.
Is such a weather pattern safe for keeping fish like neons and angels outside during the summer? If yes, is it safe to keep the containers with fish directly in the sun (all day)? (With plants and rocks to provide shade.) Won't the sun raise the temperature too much? I bet the water would be around 90F ... won't they die in water this hot? This is because the air in NYC is HOT ... the air itself! It's not just sun ... but humidity makes the air itself very hot, even when you sit in a shaded area. There's just nowhere to hide from heat in NYC in the summer, unless you go home and turn your A/C on (or if you have central A/C). Or should I keep them in shade all day (if it would be safe for me to keep them outside)? But if I do that, the plants will get no sunlight ...
