Hi Rich,
You have a fairly small tank, so you are going to have to cycle well. Do you know what cycling is? If you don't check out the begginers resource center. There are a few steps you will have to go threw before putting in your fish.
1. Decide what fish you would like to have. I recomend choosing one starter fish (example: White Cloud Mountain Minnows), one seacondary fish (Example: Cardinal Tetras) Your tank will proboly not fit any more fish. So try and decide on two easy to care for, peacful fish, and then do all the research you can on them. Talk to pet store people, friends, fish forums, etc.
2. Decide on the plan of your tank. Are you satisfied with the plan of your tank? Or do you want something else? I would highly reccomend adding live plants- Live plants clean the water of your tank, keep away algae, and proide refuge for timid fish. IF you like this idea, choose easy to care for ba backround plants like Green Cambomba, or Amazon Sword. You can put your wood in the front. This will create a naturel feel, especially if you grow a little Java Moss on the log.
3. Fishless Cycle Vs Fish Cycle
You them must decide if you want to carry out a Fish Cycle or a Fishless Cycle. If you don't know the differnece read up on them in the begginers resource center. Fishless cycle takes alot longer, is more expensive, but is much better for your fish. a Fish Cycle is fast and easy, but is very bad for your fish. Think of it this way. Do you want the best for your fish, or the best for you?
4. Test the Water
First thing first: Get up and remove the fish flakes from your tank.
Done it? Good. You see, left over fish foor creates un nessesary Ammonia. There already is a large quanity of Ammonia in your tank- My doing this you are just drivingg it over the edge. So now, to get back to topic, you need to test the water. I reccomend using drip tests, The basic tests are Ammonis, Nitrite,Nitrate,pH,and Water Hardness. Read up on your fish's water chemistry before you start this process.
5. Cycle the tank
Using whatever meathod you have chose (See above) you can now start cycling the tank. I bet you now realise that setting up a tank is a big thing- It will take over a month- But you have to realise, this will all pay of. Soon you will have a beutiful tank, full of fish, plants,wood.etc.
Conclusion: Well, have fun setting up your tank. If you have any questions, post on my wall, or on the forum. Remember- There is always a friend at the Fish Forum.
Have fun, Rich!
Zophie.
P.S Could you please tell me a little more about your tank set-up?
