Help-Fish Dying

[A_fisch]

i have a 75gallon salt water tank that has been up and running for about 4 months now. I have 2 clowns,1 banghi cardinal , 1 cleaner wrasse, 1 blue hippo, 1 flame angel , 2 skunk cleaner shrimp and 5 snails. Recently I had purchased 1 blonde naso tang and 1 blue throat jaw trigger together. After 6 days the naso died. I replaced the naso with a blue powder tang. The blue powder died after 5 days. I did not replace him. Two weeks later the trigger died. What could be causing this, any insite will help.

Did you qt them?

They were quarantined at the store before they were brought to the house.

That's usually not enough. Stores don't QT long enough, and don't usually do it correctly.
What are your water parameters?

The gentleman that comes to my house tested my water 2 weeks ago and said everything was good and levels were good

Is there anything unusual about the fish, white spots?

 

[A_fisch]

The fish are qt in a copper treated tank at the store too if that matters

All fish were great looking fish when we got them , blue hippo now has white dots all over it, and toward the end with the trigger , it had dusty white spots on it . Naso tang and powder blue did not show any bad signs

You know the old saying, if you want something done right, dip it yourself.

Possibly Marine Ich, Maybe qt them again and treat them until its completly gone.

If it was ich, his whole tank is now infected. That's not good.

 

[SourAngelfish]

If its a fish-only tank just treat the tank

 

[SourAngelfish]

oops didn't see the snails and shrimp

If its a fish-only tank just treat the tank

The tank also seems a little over-stocked but you can deal with that later, You could either part ways with your inverts or move them to another aquarium and treat the tank unless you want to remove all of the fish

How many fish should be in a 75 gallon and I'm kick ick to treat the tank now

Of you put copper in the tank, you can't pour the inverts back in it. Also the rocks and all will absorb the copper and contaminate it. Better tho take the fish out, and run the tank fallow for 76 days. Treat the fish in a separate tank

I think the tanks a little small for the hippo and naso tang

 

[A_fisch]

So take the fish out and treat them separately . While doing that reset the tank? What do you mean run the tank fallow for 76 days ?

It's a baby hippo , does that matter ?

This is a classic sign of marine velvet. I encourage you to read this thread.

You have some work ahead of you if you want to save these fish.
