please help!!! all new fish die within a week!!!

Question
Tyler, please help. here's the background info. Tank was setup on May 20th 2008. 46 gallon bow front with 10 gallon sump running two fluval filters. a total of 60 gallons of water. A fluval 305 intake from the sump outflow into the main tank. a fluval 205 intake from main tank outflow through a 9watt turbo twist uv sterilizer 180 gallon/ hr flow rate. protein skimmer, heater and additional filter media in the sump. 10 lbs of crushed coral in sump, 50 lbs of live sand in main tank, and ~20 lbs of cured live rock. we cycled the tank with black mollies and cycle for two weeks. levels taken every two days. removed mollies after two weeks and put in one fish a racoon butterfly. waited 8 days and added second fish a volitan lion, third fish was a sebae clown, he attacked the butterfly and killed it. we added a flame angel and it also was killed. next we tried a dogface puffer, which is doin very well still as is the lion. We added four damsels to get the tank going, three are still okay. we noticed ick on several of the fallen fish and the most recent ones seemed to succum to fungus. here is the list of fish that have died. all within a week of introducing to the tank all from the drip method. racoon butterfly, flame angel, koran angel (lost color ick), sailfin tang, hippo tang(ick), two percula clown(fungus), clown sweet lips (lost color), blue face angel.
we got rid of the sebea cause it was stressing all new fish but the new clowns were added after the sebae was removed. we also have a small snowflake eel, 3 turbo snails and 4 small crabs. one damsel had ick, we removed it from the tank. we are spending alot of money on fish and they are all dying, we are getting frustrated, please help.

Answer
Hey Kimberly

sorry about all the deaths!

Lots of those fish need large tanks over 100g like the volitan lionfish, sailfin tang, dogfce puffer, racoon butterfly, koran angel, and hippo tang. overstocking might have had a bit to do with it. Im thinking that the ick outbreak was caused by getting one fish that was sick at the store, then it transferred to your other fish and the chain continued. If you can, get a 20g-33g tank as a quarantine. when you get new fish, put them in the quarantine for 2-3 weeks so if they get sick, its only them and it wont transfer over. you can also put a UV sterilizer in the quarantine, which kills ick and free floating parasites.

to help the current situation, isolate the currently sick fish for 2 weeks and treat the ick with a appropriate med, and keep a eye on the fish in your main tank to make sure theyre healthy. once the currently sick fish are better, you can return them to the main tank. this should break the chain of ick and providing you quarantine thereafter, things should be healthy

best of luck!
