Help spots forming on fish.

[windcoast reefs]

Okay first off, before you go and stress the fish out further, you need to make sure that its ich. And maybe wait for a few other people to chime in with ideas before you tear your whole tank apart.

A few things you want to ask yourself,

Is it scratching on rocks?
Is it spreading?
Is it eating?
Does it look stressed?
And what does it look like (small pure white dots that are solid, or are they transparent)


Watch the fish for a day or 2, and if you see all the above, then consider treating them, I prefer chloraquine phosphate rather than copper or hypo, its much easier, quicker and allot easier on the fish ( you still need to leave the display empty for 6-8 weeks though)

One thing to keep in mind is that Tangs can form small calcium deposits on there fins (usually kinda transparent and a little larger), so it very well could be that, one of my tangs has 2 spots, they have been on him since I bought him 2 years ago and they are small calcium deposits that have formed on the fin (do a search online and you will see a bit on these)

Also I find that if a fish starts to show signs of ich your much better off to try and keep them fed, add amino acids to the food, and try garlic extract, at least until your sure that you have to take them out of the tank.

And no ich will not spread to corals, only fish.
