I've read from people that fish can go without food for 3 weeks but does that apply to neonz?
Since neons and ghost shrimp have similar preferences, they work well in a tank. You will want to get a smaller tank (in the ballpark of 10 gallons) and plant it densely. You can mostly feed flake foods with the occasional treat. Combine ghost shrimp and neon tetras only with other small, peaceful fish, as anything aggressive or predatory can eat or bully these species easily.
It's best to keep your neons and ghost shrimp with other small, peaceful fish. Ghost shrimp are frequently sold as "feeders," or food for larger fish, and neons are about the same size. So don't keep them with large, aggressive, or predatory fish like freshwater angelfish or other large cichlids. You will also want to be careful of your water chemistry. Ghost shrimp are tolerant of a wide range of water conditions, but your neons are not. Neon tetras require soft, acidic water. Don't mix them with fish that require basic, hard water since you can't have both at once.

How the heck do you feed neon tetras????
I added this site to my favorites list last week, and have been reading a lot.
I just put 5 neon tetras and two corys in a 10 gallon aquarium yesterday. It has a heater and filter and plants and flourescent lighting. It's really the second setup, as I had 3-4" tilapia and bluegills in it previously. I cleaned the glass, rinsed the gravel, refilled with rainwater, put the plants back in a couple of weeks ago.
Just wondering what the neon tetras like to eat best. They don't seem much interested in the goldfish flakes or bettamin that I have. Do I need to get some freeze-dried or live food for them?
The little cats are happily eating the food I put in yesterday (off the bottom).
thanks Dawn: I don't know why Ed's link isn't working, it works fine for me. I guess just try again later?
The fish have a good chance to survive if you get a test kit, and a gravel vac, and prepare to do daily water changes. The test kit is to tell you when you need to change water. The gravel vac is to make the changes easier. You can use tap water, you do not need to collect rain water. You will need a water conditioner such as Prime to use when you do water changes.
The bacteria dies off when it does not have ammonia to feed it. It starves to death. Also, cleaning it in the shower killed off bacteria because chlorine will kill it. Once it's dead, it's just like anything else dead, it doesn't just reestablish. It will come back ... it is a naturally occurring bacteria, but it will take 6 to 8 weeks, most likely.
Neons will like and will eat freeze dried blood worms, but it is too rich to feed them all the time. The need flake food for daily fare, then the blood worms for a weekly, or every 10 day treat.
It's good that the neons have good color and their fins are not clamped. However, not eating is a sign of stress. You really need a test kit and a gravel vac right away, like today if at all possible. You can get the test kit at Petsmart. Look it up online at Dr Foster and Smith, or Big Al's online for the best price. Print out the ad and take it with you. Many of the Petsmarts will match the price on the ad. The ones here will, but some won't. Doesn't hurt to ask, and it saves a bunch of money.
ETA: I want to add that you should not be feeding more than the fish will clean up in a few minutes. If food from yesterday is still sitting on the bottom of the tank today, you are overfeeding, and that will add to your ammonia problem. That's why you want to cut back to feeding every third day, and only what they will totally consume in about 5 minutes.
