i was planning on getting a 29 gal tank
Like it was mentioned before, 29 is way too small. You can pick up a 75 gallon tank for about $115 without a stand.
Do you mean a bubbler?
Don't go cheap on the heater. I'm really not quite sure what temps a morays prefer.
and some sort of cleaning fish
Morays need to live in brackish water as they're younger and closer to saltwater as they age.
You'll need to get aquarium salt and keep your specific gravity around 1.08. With a brackish tank SG stability isn't something you need to worry about in my opinion, as the fish are used to constant change. As long as you stay within +/- .01 between water changes, you should be ok. Now the cool thing you can do here having a brackish tank and all is to get a really cool cleaner. If you can find them at local fish stores you can get some species of stingray that stay pretty small, with a diameter of 8 inches or less. You could also throw a puffer in there if you wanted. Some good species are the figure 8's and green spotted. Although the figure 8's might become lunch as the morays get bigger, but you shouldn't worry about the green spotted.
Or you could just skip the whole brackish thing and go complete saltwater, but brackish is cheaper and easier.
should i get more, if so which ones and will it make a diffrence.
Here is a good list of the equipment you need for a brackish tank, what is involved in setting one up, and what other sorts of fish are available in brackish water.

A forum i read said to get a home testing kit.
You'll probably need a basic testing kit. The Saltwater Master Test Kit should do it.
Morays are pretty messy. You'll be needing one.
which i dont know if that will be needed. i dont plan on haveing a alot of fish, 1 maybe 2 moray eels and a cleaner fish.
I wouldn't but more than 2 Morays.
what should i feed it when i get it?
I don't believe Morays have a very good sense of smell, but I could be wrong. They don't seem to pick up on anything that doesn't move. You can buy feeder fish (Rosies or something) at your LFS for about a dollar for an amount of 12-20 feeders or something like that.
I would suggest putting about 15 feeders in per moray per week. They'll probably eat all of them within 24 hours, it's amazing to watch them eat. They poke their heads out of the rock, grab the fish with their mouth, and drag him back into their cave. One can only imagine the horror of the fish.
should i get more than one? if i get more than one will a 29 gal tank be big enough?
75+ and you should be ok for two morays and one or two other larger fish as long as you have a good filter system.
My friends current brackish setup has 1 Moray, 1 Snowflake, 6 Mono Sebae, and it used to have a green spotted but he killed over.
Hope this helps!
