A problem with Tubastrea.

[salfegio]

I have a small problem with my sun coral Tubastrea. This coral is covered by gray-brown mud. What is more that mud covers first top edge skeleton and then this mud penetrates inside coral polyp and he in length of time dies. What is it, someone knows?

I apologize for my English language bacause i'm from Russia.

Are you referring to Brown Jelly Disease? Please google it.

Any image you can provide would be of assist.

This "mud'' you describe could also be sponge?

As always water parameters posted helps with trouble shooting.

What are you feeding the coral and how often?

Thanks, i have reading about it, but brown jelly disease is not my problem, because those photographies what i have seen not resemble on my problem. And when a coral is ill Brown Jelly then he dies in one day and my Tubastrea is living some two months.

Any image you can provide would be of assist.

Mud resemble more accumulation of the fish faeces, but I have only 3 fish and they cannot **** this much...

Water parameters i measured long ago...

I am feeding the coral artemia every other day

Looks like a type of algae growth, just a guess though.

Perhaps try a different location in the tank perhaps with a tad more flow.

Definitely look at your nitrate and phos level though.

Hope someone else chimes in.

Weird, looks like it could be an algae that's causing some kind of infection. Since they don't need light is there somewhere in your tank that you can put them that has very little light but still gets some water movement, like under an overhang or something?

Also, artemia and other frozen foods do a lot more to foul up your water quality than feed your corals, plus they also have little nutritive value so they don't do much for sun polyps. Try grinding up some pellet food, soaking it in tank water for a few minutes and then feeding them that, it's like steroids for sun corals and have a really small effect on your water quality compared to frozen foods. If they're fed healthy food they'll outgrow the algae, you probably won't even recognize them after a few weeks
