coral sliming?

[victorsfish]

Hello,
Can anyone tell me why the coral in my salt water fish tank is sliming?

 

[Navarre]

What type of coral is it?

Thanks for your reply....................
Let me give you the stats. on the entire tank ....... maybe that would be more helpful.

The tank is 12 gallons
Its a sub straight with crushed coral on the bottom
I currently have 2 brain corals, 1 long tenical coral (which was sliming and then died
2 disk corals
I also have a 12 pnd. live rock which I suspect a bristle worm may have stung my long hair tenical (could that have killed him)
I also have a flame angel which is fairly new to the tank.........I have read conflicting info on this fish............ coral friendly/not coral friendly
I am giving the tank 12 hours of 18 wt actinic light and 12 hours of 18wt daylight

any help you could give me would be wonderful

once again............ the l/t coral was sliming.......one of the brain corals was sliming also.........the l/t died....

 

[Navarre]

were any of these corals tht were sliming close to each other?

Flame angels are fairly safe IMO. Most dwarfs are safe but you always get one that hasnt read the rulebook

Bristleworms are comon in almost every tank and its very rare for them to attack corals unless they are extremly large.

well what do you consider to be close..... they are approximately 4 inches apart from one another.
I am more concerned that the flame angel is acting weird since the long tentical died and polluted/clouded the tank. Since then I have done small water changes.

Could the long tentical coral have polluted the tank enough to endanger the flame angel fish now?

So what is your theory on the long tentical coral plate dying?
Thanks for your help-

How what, how much and often are you feeding? What are your water peramiters?
How much flow do you have and what equipement do you have on the tank?

 

[Navarre]

My theory was that the corals may have stung each other and cuased one to die. Some corals can send out sweeper tenticles up to 6 inches away and these carry powerfl stings.

The coral will have poluted the tank once it died, you angel may well be under stress for poor water condtions now if the coral has been allowed to make the water cloudy.
I would do an immediate water cahnge to try and dilute the problem.

When in doubt, "dilution is the solution"

 

[victorsfish]

There is a fire shrimp along with a flame angel and some hermit crabs...... the only thing that I am feeding the tank is 1/4 inch of brine shrimp per day...... and coral sollution for the corals.................is that enough?

please see Jan. 6 posting for all of the spec. on the tank.

Thanks for your response...............

HOw long had the coral been in the tnak before it started to show signs of trouble?

I had a similar problem with plating corals (all i have kept) and i didnt undrstand it. Someone told me that magnesium was more important to LSP corals than SPS corals. I started to dose with magnesium now and the corals are beginning to grow back (the LpS corals ) so i guess there may be some truth in this.

Can you get some water to your LFS for a magnesium test?


failing this.. how long was the coral aclimatised for? These corals tendto be very delicate when first introduced to the tank. THey are alkso extremly fragile and any tiny break in their skin whenintroduced can cause infection to take place and kill the entire coral.

Just a few suggestions, hope they help.

I don't want to sound confrontational here, so please don't take the following that way. It is our goal here to help. You have not provided "all of the spec. on the tank." How old is it? What equipment (skimmer, fuge, anything?) is attached? What are the water parameters for s.g., pH, calcium, alkalinity, magnesium, phosphates, ammo, nitri/ates?

What do you mean by "disk coral"? What kind of brain corals were/are they? What other corals are in there if there are others not mentioned?

My guess, though, in spite of the outstanding questions, would have to be that your tank is new, on the order of a weeks or a few months tops, because these corals can't survive on 18W PCs. At least, I have never heard of anyone keeping LPS and SPS successfully on such weak lighting.
