You should consider quarantine before adding several fish to an aquarium at once. The added stress and possible parasite introduction could cause serious problems for your tank.

Your water quality could use some help as well as well as more water movement with surface agitation as the others have said could help.

I agree with the waterchange suggestion. If something's lookng awry in my tank the first thing I do is test the parameters, then do a water change.

The Sailfin Tang was a very poor purchase choice for that size tank. As much as I absolutely LOVE Sailfin Tangs, they grow HUGE quite quickly, and need very large tanks.

NH3 should be 0. A good sized water change is in order right away.

The fact that you have any amonia showing up indicates that you have added too much too fast. Either that, or you jumped the gun and stocked before the cycle was complete. I assume that since you had some stock in the tank that was doing ok prior to this, that the tank has been running for at least a little while.

You should never have detectable levels of either amonia or nitriite. Nitrates are more tolerable, but not desireable if too high. Your nitrate level would not be excessive on its own, but since you have amonia reading, it is pretty certain that you also have nitrite levels as well. Add in the nitrate, and you have your answer on why things don't look good.

I would suggest that you need to temper your enthusiasm for rapidly stocking your tank and add one fish at a time, allowing at least a month between to allow the bacteria cycle to catch up to the added bio load. For now you need to do water changes; do them large and often until things stabilize.

I understand adding more than 1 fish at a time is not adviseable. However living in the okanagan there is really poor selection and you pay 3 times what you pay for a fish on the coast. I figured 3 relatively small fish would be ok and i'm still confident they will be. The tank has been running for almost 6 months so i think i've been pretty patient adding livestock.

I did a 25% water change this morning and everything appears much happier. I'll test parameters again once everything has had a good chance to circulate.

Thanks for all the suggestions.

How does your flow work in your tank? Do you have a tank journal? You may want to move your koralia power head closer to the surface, or add a second power head in to oxygenate the water more.

Keep up with your water changes, and maybe look into some sponges, like a nitrate sponge, as something to keep on hand for emergencies.

How about some photos of your cylinder tank? I'm really curious as to what it looks like?

Sorry, no tank journal. I regret not starting one but i didn't 'do' canreef when i started. I knew completely nothing about fish tanks when i started. The amount of time i've spent reading and researching i probably could have been a lawyer by now and i still know very little. If i had a $1 for every liter of water i've spilled on the floor i'd be as rich as a lawyer as well.

I like the idea of another power head, gonna order one.

Here are a few pics...
