Help!!! Tank has been invaded

[eddtsk]

Hi, some time ago I saw some blue eggs in my tank that I think came out from my Turbo snail, but now I got hundreds os unknown slugs dirturbing my button coral. They are the extra protrusions from the closed buttons.

The button coral use to open fully but now it won't. There are even reddish substance covering the coral.

What are these slugs? Are they really the decendents from my Turbo snail??? Are they harmful??? Is my corals in trouble???? What can I do??? I really got no idea now... : (

bro...think ur pic too big.... maybe any mods can help.. if i dint see wrongy.. i saw nudi on ur colony.. u may ned take out and do a freshwater dip(not more than 5mins)..

Good luck..

i don't think they're slugs...

First of all, you picture needs to be re-sized.

As for your question. If the slugs are attacking your buttons, they should be Nudibranchs. Do a 5mins Fresh water dip of the buttons and follow by either shaking the whole rock of buttons or use a spray to spray off the Nudibranchs.

[veliferium]

Picture too big,most probably are nudis,u can kill them by a FW dip or lugols dip...

[Lin]

see the one in red circle, those are nudi.. and circle in green are the eggs.. remove them in no time.. juz take them out asap for cleanup..

[Jimng]

The zoos are in very bad shape, i would suggest to savage those that are still opened (cut and glue to another rock-remove all nudis and eggs with FW flushing or lugol dip), and throw away the rest......

[AlfaRomeo]

Personally, I would dump the whole colony away. Better be safe than sorry at this stage.

ur zoos looks like it's in a bad shape...

apart from getting rid of ur nudibranch, i suggest u do a check n improve on ur water quality as well as circulation... cos the cyano looks bad n they will cover ur softies if uncontrolled

Sorry for the large image size, look small on my comp until I post on the site.

Will go try the FW treatment. Thanks!!!!

Hi guys, guess what. While I am flushing the coral stone. I some worms drop out of it. Even better, a crab!!!! I never know I got those in my tank!!!! I put all back into the tank after flushing. Have to wait for the result tmw!!! All the best to the corals!!! Heartache if throw them away....

[typrobin]

keep flushing with FW continuosly for about a month...do it every other day...it should more or less clear most of it...but it will still come back...

zoos will not die easily from FW dips...

[Dispar_Anthias]

IMO throw away that colony of zoos... got nudi, got eggs got cyno.. damn jialat... throwing away is better as it reduce the chance of the nudi spreading

[ho19829]

looks like your zoos should survive. Got some big ones still intact

Do more fresh water dip until nudis are exterminated.

[decentkid]

bro...IMO...its better to throw away the zoos...once a coral can even be covered by cyano...it already shows how weak the coral is...

[damienkee]

mayb u should put in QT beside of ur main tank! watch it for few months! me oso heart pain if throw it away!!!

[damienkee]

but if that is the only 1 solution to safe ur others coral, i think u should follow those advice!!!!! to throw away!

[eddtsk]

I monitored the button today, opens little. maybe from the shock of FW. But think its surviving. Hope for the best.

As for the cyano, I brush some off with my finger while washing. So most of them gone liao. All these happens quite fast, in matter of days.

Mine is only a 2 feet tank, before I put the buttons in, my tank was full of cyano, but finally remove them by changing filter to cannister with bio agents. Not much corals left liao, so worth a risk to salvage whatever in there.

Hi guys, think my buttons ok liao!!!! Thanks a lot!!! Attached are the buttons now!!!

[eddtsk]

Here are some of the neighbours of my buttons!!!

[eddtsk]

Not sure what are these. looks like trees.

[eddtsk]

These are small ones that looks like umbrella!!!

[Lin]

Hi guys, think my buttons ok liao!!!! Thanks a lot!!! Attached are the buttons now!!!

Glad to hear tt..

[weishun]

Hmm very fast recovery dude. Congrates.

But for your red slime (cyano) problem, be sure not to overfeed your corals and fishes. Reduce lightings and increase your water circulation. Hope this helps.

All the best, happy reefing.

Wilco!!! Thankz!!!!
