Don't use Fish! Get a cocktail shrimp from the grocery store, aprox 1 1/2" to 2" without the tail and just pop it in your tank and let it rot, that will start your cycle off whithout hurting or killing any fish.

You leave it in there and monitor the ammonia level. It will peak and then should drop back down to zero. This will take anywhere from 2-4 weeks. After that you may remove the shrimp, what you do with it from then on is up to you.:D

Yes we are sure, if your not convinced do a search on this site for "cocktail shrimp" You'll fine 100's of threads about it!

its better if you read instead of question someone who goes out of his way to write you a response.

you could just let the live rock cycle your tank... there will be plenty of die off on it to push the cycle. (I assume your rock was live and not dry reef bones) but the cocktail shrimp method makes complete sense to me too... the object is to generate ammonia to "feed" the bacteria... if you search "cycle" you will be absolutely overwhelmed by the amount of info you will find!!!
So, just for a simple answer... dont add fish until you "see" (by testing) the ammonia go up then down and the nitrates go up then down lagging just behind the ammonia levels.... then when you have NO (zero) ammonia and nitrITEs go ahead and add some fish.
I think clown fish are pretty hardy but I would recommend the run of the mill nemo percula... other species can be prone to dig in your substrate
good luck... dont rush it ...this is set-up time is some of the most fun!!! and do your testing... you will get a good feel for what is going on with the ammonia, nitrite, nitrate thing

I got this from a site you can thank me for finding it but I did not type or come up with it I just copied and pasted.
NEW TANK CYCLING
Hi all. Lot of questions ALL the time regarding tank cycling. Here is the method I use and recommend. Hopefully save having to try and remember everything every time we answer or having to search for archived threads.
Tank Cycle Instructions
Set up tank with substrate and any base rock, or uncured live rock if you are going to cure it at this time. Also hook up your heater as well. At this time, do not put cured live rock in the tank. The object is to completely cycle with no die off on live rock. Add about two or three DEAD cocktail-sized shrimp for every 50 gallons of water. The shrimp can be raw or cooked. Keep good water movement in the tank by using powerheads. Circulation is important. If you are using a canister filter/other filter with bio-media, turn that on after about three days. If you are using a protein skimmer, turn that on after 10 days. This will allow excellent decay and ensure that you effectively peak your ammonia cycle. After two weeks, the ammonia should peak and nitrites should be starting to rise. In simple terms, the ammonia converts to nitrite, and then the nitrite to nitrate. Four weeks after you start the cycle, the nitrite should be peaking, and starting to fall. You should now start picking up your nitrate readings. Nitrate is not fatal in the same ppm range like ammonia and nitrite is. However, this applies mainly to fish. Corals, for example, are far more sensitive to nitrate than are fish. However, it is desirable to keep nitrates as low as possible even in a fish-only environment. Water additions and changes generally remove your nitrates, and over time a biological filter can be built up which will break down nitrates as well. Spent gases are released through the surface exchange, which is made much more efficient by using a powerhead to break the surface. After about six weeks, you should have a completed cycle, and now is the time to introduce waste-producing organisms (fish) to maintain that cycle. Also, if you now add your cured live rock, you will not have an ammonia spike killing off beneficial life. Some begin their tank cycle with non-cured live rock, and in the process effectively "cure" the rock. However, I recommend the shrimp even in that situation as it produces an excellent amount of decay and boosts the ammonia to start the most effective cycle. One thing you do not want to experience is adding a fish to a tank you "thought" was cycled with live rock only to have another ammonia spike with potential fatal results. This would be the case particularly if the life rock you cycled with did not produce sufficient die-off to peak your initial ammonia-nitrite-nitrate cycle. On a side note, this will be when your tank smells it worse, and potentially looks its worse. You still might experience your brown diatom outbreaks and possibly at least one red-slime algae outbreak. This is all natural and no sign of poor husbandry. Your tank must "get worse" to "get better". This is why allowing sufficient time to cycle is so critical.
AS A DISCLAIMER: There are MANY ways to cycle a tank, this is just a tried and proven way to get the results of a complete cycle. There are variations on the methods described above. Some people DO cycle with live rock. There is no one "right" way to cycle, but several proven methods. This is one such method that will get your start in the hobby off in the right direction. You will learn the patience of not adding fish prematurely, and hopefully take the 6 weeks cycle time to do some informative research and general reading in the hobby. You will find that after your tank is cycled and you have spent that time reading, you will attain a secure level of comfort that you "have an idea what this is all about." This is the most important time you invest in the hobby, for it will dictate whether you nurture your passion for marine aquaria, or become frustrated with "too many problems." Again, this is not the "only" way to cycle a tank, just one of the most thorough. Too many people lose expensive livestock by rushing their start in the hobby. Patience is a virtue, and if you can't "hang on" for six weeks, it is a good indication of which way you will go in the hobby. As you gain experience, you will find that you can "instantly" set up a fully cycled tank by using water/substrate/liverock/bio-filtration from an established tank. Don't confuse this method with a brand new tank, brand new water, brand new rock, etc.
Good luck, have patience, research every fish/coral/invert you purchase and you will find the rewards of this hobby are nonstop. From personal satisfaction to friends/family marveling at your tank, you will feel a personal sense of success and satisfaction that comes only when you "do it
right." Unfortunately, you will lose fish. It is your responsibility to make sure you don't act in such a way as to promote stressed/diseased/dead fish. That is the difference between a marine hobbyist and a person with a saltwater tank. Always ask questions, always get many opinions, and have enough of a foundation to sort through and make your own rational decisions. And remember, when you think you know just about everything, its time to crack some new books because aspects are changing constantly and nobody I know has EVER mastered this hobby. I hope this helps out some newcomers to the hobby with questions about cycling. This method is in my opinion the way to go over using live fish and subjecting them to the burning of ammonia and potential death therein. Keep a log of your ammonia-nitrite-nitrate levels as you progress and you will see the closed-system eco-cycle unfold before your eyes. You will also accurately
determine when the correct time is to add fish. Six weeks is the general approximation, but can vary depending on every tank setup, and filtration methods used. Happy fishing all, and welcome to the most stressful, peaceful, agonizing and fulfilling hobbies I know of!!

it is really cheap my mom picked up 6 for me after she got off work. 4 for my main and 2 for my QT and it cost her $0.32 from walmart but our walmart has a seafood department and the other warmarts around here dont. you could probly get them at a local bait shop for fishing.

And yes a grocery store "considering they sell them just like the walmart" my grocery store dont sell them.

definetely the shrimp method. alot of times if you dont use too much shrimp some people let the shrimp completely rot in their tank.
