Some help please - pic added

Anyone who can help or give suggestions I'd appreciate it.

My two clowns have formed some sort of dark coloured spots on them. The spots dont seem to be in any order or specific size or shape. It resembles ink dots. To my knowledge, the fish are rubbing themselves on the bottom/corner of the tank once an hour or so. Scratching whatever is on them. I assumed it was ich, but all my research says ich is small white spots. These spots are dark in colour and bigger then a grain of sand.

All my levels are correct. I've had the fish for 1 year now. They are the only two fish in the tank. I have recently (10days-4 weeks ago) added some frags and live rock from OA in Vancouver. I add a calcium additive now as well.

I am trying to get a picture of it, but its proving to be fairly difficult to get a picture that shows.

Someone? Anyone?

Thanks alot,

i agree it sounds like black ich, I just went through this with my yellow tang, all i did was fresh water dips once a day for no more then 3 min for 3 days and the ich went away, if you notice the fish being stressed out. like trying to jump out of the plastic container stop, also some people recomend formalin dips but i dont know anything about using that method.

thanks alot

how do I diagnose this for 100% certainty?

is there something I can read on these freshwater dips so I do everything properly?

thanks again

good article
if you can post apic of the spots that would help,

[Noj]

you can sort of see the spots on the back half of the the fish.

Hopefully this helps a bit...I'm still trying to get a better shot.

oh man It looks like my Saddleback clown has got black ich too!! and my tangs are scratching.

That does not look like black ick to me. It looks like your clowns have been rubbing up in something (a coral) and it's giving them the spots. My clowns have this as well, the rub up on LPS corals like Frogspawns...

Do yours do this?

I agree with Scott. My clowns as well got this after hosting in some Xenia. I believe its a skin irritation. It went away after I removed my Xenia and has not come back since.

DOes not look like black ich to me, I had a tang who i thought had black ich, turned out was normal ich but from rubbing and being alittle bleached looking appeared to have black spots, but when i turned the lights on fully the spots disappered.
