sick zoas... ?

[Scootk05]

i had a colony of neon green zoas my cousins gave to me form california. they opened up after a few days, but i noticed some green plant looking algae on them so i tooked them out one day and picked off the stuff and ever since then only the smaller half of the colony opens. (about 6-10 polyps) the bigger side on the right stays closed all day.

the other half is a kinda brown color and doesn't look like the other half this is happily on purple coraline alage.

also, i just did a zoa dip and lightly scrubbed them with a toothbrush and this weird brown/clear looking crud fell off them.

You likely brushed them too hard if the brown "crud" came out. I believe that is the symbiotic algaes within it, but I wont guarantee it. I know that I've accidentally squeezed a polyp or two a little too hard with the tweezers when fragging and that's happened. No guarantees though because I've had some that I brush lightly and that happens too, but they were not healthy to begin with.

The ones on the right of that image look like they are goners. They are translucent and look like they would just desintegrate if brushed again. For future reference, tweezers work well too for removing algae between the polyps.

I think the problem might be stress on them. What kind of lighting were they in previously? What are your water parameters - and are those the same, or similar to that of the previous tank? If they were under a lower light in the other tank, they might be reacting to the light, but my guess is that between transporting them, the initial removal of the algae, and the FW dip with the brushing that they are quite stressed. I'd say that unless the lighting is dramatically different, just leave them alone for a little bit and let them stabalize in the tank. You might get lucky and all of them will come back.

I would "cut your loses". Shave the top portion of with a razor blade. It looks like you'll have some polyps come back on the bottom right of that rock. One healthy polyp is enough.

Good luck.

im going to try your idea. but instead of going through the hastle of scrapping off the diseased zoas i just fragged the pieces that were good and quarantined the bad piece. (gunna see if it'll perk up maybe.. -_-)

also i have some weird orange leather look stuff on the back of my piece of zoas. could i get an ID ?

the first picture i posted was actually before i FW dipped them and scrubbed them. thats what they looked like before... after i scrubbed them they looked about the same. dark dark colored and kinda tightly squeezed up. lighting is the same as before. i moved them higher up in the tank because the piece of rock that they were on was curved and i thought they weren't getting enough light to open up.

they started initially closing up and not coming out after i gently used my hand to pick some algae out between them. and they were never the same after that.... -_-

the orange thingy is some sort of sponge
