What's the difference between a new and an older setup if the parameters are fine? And the lady told me she would take it back and trade me a Bubble Tip Anemone that's 30$ more for free. Also, I'm going to take back my tank raised clown and try and give back my yellow tail damsel and try and get a wild Clown tomorrow.
As mentioned a mature tank has well established bacterial populations, as well as microfauna. When a tank is new it goes through many changes. You are currently creating many changes for your tank, and having sensitive livestock at this time is very stressful on them. Even if you weren't making any substrate changes, or fish changes, the tank itself will go though different fluxes as it tries to stablize its bacterial populations. Once you have had your tank set-up and without change for almost a year, you will know what is normal for your tank. In my mind some questions to ask yourself when considering if your tank is mature or not: What will your tank do in the hot heat of summer? What effect will that have on your livestock? How much is it going to evaporate on a normal basis? What about when winter hits, what kind of temperature fluxes will you have? Will your parameters be swinging while you attempt to keep your water chemistry in check? How are your water parameters? Have you gone through algae cycles that follow a normal nitrogen cycle process? What kind of issues do I see if I feed too much?
Your tank is not mature right now. You are changing livestock around, and your tank needs to adjust to every change you make. If you feed too much one day, your tank will have to compensate for that....changing out fish will also cause your tank to flux and it will need time to recover from that change. Stability is key when adding something like an anemone. As you can see the more mature your tank is, the more stable it's various micro populations are, and it will be able to handle change better. Please, do not get the bubble tip anemone until your tank is older, and you are more experienced to try it. Your lighting is still insufficient for the anemone. Did you read the links I provided in my earlier post? Perhaps the LFS will allow you to wait for your tank to mature 9 months or so before you collect on their offer.
As for wild caught clownfish, as posted previously, please try and stick with captive raised, when at all possible. Wild caught clownfish can have a slew of diseases you may have to deal with. If you insist on wild caught clownfish, then please research their diseases. Here is one article, and I encourage you to read more:
Clownfish Disease Why not keep something captive raised and hardy? I would recommend wild stock to more advanced aquarists. There are many species of clownfish available that are captive raised.
The more research you do now, the better. You will save yourself and your livestock alot of stress (& money). Your livestock is in your care, so you owe it to them to learn as much as you can, and provide them the best environment you can.
