sick fish

[abe28]

I have two ocellaris clownfish, a blue damsel, and a diamond watchman goby. They are all breathing rapidly and all of the sudden not eating. My ammonia is 0, nitrite is 0, ph is 8.2, nitrates 10ppm. This is a fish only tank with live rock.I also have a hob filter and powerhead aimed towards the surface, so I don't think it's an oxygen thing. What could it be?

Also there are three red crabs in there and i have seen them for a while, could this be the issue?

It sounds like high ammo or nitrites to me if they are all gasping for air. What kind of tests are you using?

 

[abe28]

I'm using the api saltwater test kit and it's only about a month old. I tried putting some of seachems prime in, but i haven't seen a difference.

What's your temp at?

 

[abe28]

It's at 79 degrees

Did you just add them? How did you acclimate?

The blue damsel has been in there for 2 months and the two clowns a little over a month. I let the bag float for 20-25 min then gradually poured some of the tank water in and left it float some more then I put them in. The goby i got a week ago and acclimated it the same way
