[SungAndBrian]

Hi, it is been 41days that i start my slatwatertank.

I saw something growing on live rocks.

And store gave us some snails..
(I am not sure my husband shoew the piture to store guy..)

Its been great,
And yesterday we bought our very first corals.

Btw.. i dont even know the name.. ugh, my mistake..


The problem is i am seeing the same thing, what is on the rock, on my new coral..
It is growing on left bottom of the coral..

Does anyone know what is this??
Should i just leave it??


Thank you very much.

you don't want those in your tank. they will spread like wild fire. Try and nip it in the bud now, before it's too late. do a search on them. aptashia or majano

Yes it's true Aitapsia is a plague. If you only have one you can kill it wit a vinager injection in the mouth.
