About my foxface and coral beauty having spots.?

Question

I looked at my foxface and it has green spots with little white pinhead spots on top of them. the coral beauty has small white spots and not as extreme as the fox face.
I just got these fish 2 days ago. someone gave me a link for fresh water fish diseases but these are salt water fish. so i dont think it can be ich. but maybe they can get it too. can anyone give me some information? Thanks all. you rule

Answer 1

This sounds like marine ich (Cryptocaryon irritans), which is smaller than FW, however it has a similar life cycle.

Here is a snip from one of my articles about marine ich:

It is best to move your fish to a quarantine aquarium with sponge filter that can be seeded from your established aquarium.
This hospital aquarium should also have no gravel and just enough décor to give the fish a place to hide. Try an keep this tank in the dark for the first 3-5 days of treatment
Change 25% water daily using water from your main aquarium, thus performing water changes there too. MAKE SURE NO equipment from your hospital aquariums makes contact with your main aquarium (you can soak in a copper solution then rinse in scalding hot water).
Your medication options starting with the strongest are:
*Copper Sulfate kept at 25 ppm
*Medicated Wonder Shell (Marine version)
*Malachite Green
The copper sulfate is your best bet, but this cannot be used in your main aquarium.

A freshwater dip (pH adjusted to 8.2) combined with methylene blue for 3-5 minutes will also help. I recommend using the methylene blue at double strength for this dip.
The dip is very helpful!!

Do not place your fish in your main aquarium for 3 weeks.

Watch for another marine protozoan disease; oodinium. This is very fish and affects the gills quickly where as the fish flashes against the rocks and gets VERY pale. Treatment is similar, although a copper level of 15-20 ppm is usually adequate here. This disease moces faster than Cryptocaryon and I recommend a dip even more here.
