hey guys so in my 72 gallon tank when ever we get new fish we aclimate and watch them for a while to make sure they are doing fine some fish will even last a night or two but all of my fish have died when I wake up in the morning and check on the tank....fish are dead.... I found a rock crab already and got rid of it... but we added a yellow eyed tang and two clownfish....both dead and one i couldnt even find... all of my corals are doing fine,hermit crabs, harlequin shrimp i have a conch snail a sea urchin an anemone areo crab sally light foot crab all were recommendations from a saltwater fish store..... I cant figure out what is happening and im losing alot of money.... getting quiet discouraged and thinking about quiting......I really need help!

We need water stats i'm afraid.
How many fish and which type.
How long do you climatise the new fish for.

Loss of colour and heavy breathing can be toxins, bad water quality, parasites, bacterial, ph shock.

Take a sample of your water to the lfs and ask them to write the readings down for you.
I would also strongly suggest you invest in some liquid test kits of your own.

If there fish are dying in aday or two it sounds like bad water quality, ph shock, toxins.
