Yes every fish but gold need a heater. Keep the temperature 76 to 80 degrees fahrenhei
Yes as long as your tank is big enough for them and you have a filter and heater in it. Neons are schooling fish so you need at least three of them for them to be healthy. I believe that neons get to be two inches and the rule of thumb is one gallon for every inch of fish for tropical fish. Which means you would need at least a six gallon tank in order to have neons but a ten gallon tank is ideal.
angel fish can eat neon tetras is the simple answer, but i have angel fish and neon tetras in the same tank and the angel fish does not bother the neons, although this may be because the angel fish is not full grown yet so it is a 50% chance
yes, neons are a tropical fish so they must have a heater. water temp should be around 68 to 79f, but somewhere in the middle is best I was thinking about 72f .
No but they will nib on guppy tails

Yes. Angelfish are generally peaceful fish. Given the space and diet requirements are met. Except when protecting young or around rival angelfish. (Though they can be kept in groups) Minor edit 3/3/2016: Though, let's not forget that angelfish are predators
Angelfish are compatible with:Other angelfishBarbsCory catfishDanios and minnowsGouramisLoachesMolliesPlatiesPlecosRainbowfishRasborasSharksSwordtailsTetrasThey can usually live with eels, crab and, shrimp but not always.The size of the Angelfish does not matter.
Yes.
Guppies will eat neons tetra babies but are not large enough to eat fully grown neons.
Good filtration system, a heater, balanced pH level of the water, and, of course, food. Also, don't put them in with fish which are prone to nipping at fins... trust me on this one. Black Ruby Barbs mixed in with a Betta and Angelfish.... not a good idea. Didn't kill any of the fish, but definitely trimmed their fins down.
Galaxy of starfish :D
No it is not, as you can see, the queen angelfish is much more colourful. The angelfish is just black and white. Except for the male, it is colourful but not as colourful as the queen angelfish.
