frogspawn detaching from skeleton

[md14fish]

I have now lost 4 colonies of frogspawn. They were over two years old and one by one just detatch from skeleton.
Has anyone seen this and know cause?
Other corals seem fine.

mine was slowly losing tentacles because my coral banded shrimp kept ripping them off.

Heh, uhm, yea, that would do it!

samething happened to me check our phos

polyp bailout. something must have changed and they no longer liked the location they were in, it's a last ditch effort at survival. did you change bulbs or lighting, add powerheads or change their direction? any swing in water parameters?

I just recently lost a large colony of hammer coral to the same thing, and am slowly losing a small colony of torch coral. i will admit that i was lacking on my tank maintenance. after my hammer loss i have been back on track on my regular tank maintenance, and the torch bailout has slowed down but has not stopped yet. I dont have a phosphate test so i can not tell you what that is at.

 

[md14fish]

PO4 is .o5 with colorimeter, pH 8.2, Ca 400, alk 2.5
Can't imagine any of those would contribute to this. Lighting has been consistent 2 250 watt 10K USHIO and 8 t5's

An ammonia spike could cause it. But it would probably have affected everything at once. Still couldn't hurt to test it.

Have you checked the stalk for parasites/pests?

Can you post a pic showing the skeleton in the tank?

 

[Laddy]

euphyllia are the best indicators of water quality I know, you may want to check your perimters

I am having the same problem right now.

Can I glue them to a rock or soemthing. The Frog spawn is still a live and bloated just no longer attached to the rock. I shut off the power heads because they have been floating and getting diced through it.

I don't think the loose tissue will survive very long. At least it hasn't in my experience. There may be a parasitic or bacterial agent at the root of the problem so I would remove the separated tissue and discard it to avoid risk to other corals.

Would have to be pretty bad water quality. I let my tank go last year and teh frogspawn simply died back. Just appeared to get smaller and smaller. And then it regrew all the way back and is bigger than ever. The Hammer just kept on growing though.

 

[tmz]

Another thought. Nitrates?

Mine all died when we lost our AC during a very hot couple days when the water got in the 90's. Nothing else died. Maybe check water temp? A defective heater?

i had this happen to my frogspawn a few months ago. The heads were huge and splitting. I come back from christmas vacation and one was floating around followed by the other 4 a few days later. I had a decent fish sitter so i do not think it was that. The heads still look great.

My ca was in the 520's from the salt i used, an email from Bob fener said that maybe the long term stress finally made them bail out. I guess when the ca is too high like that it can inhibit calsification. My fox coral started looking like crap at the same time but has held on. i changed salts and my ca has come down. The fox is looking better.

I placed the frogspawn heads on a large shell and placed netting over it. They still fully expand and look great other then the missing skeleton and it has been since christmas. Its been about 2 months now. I have read they can grow back the skeleton but it takes months. I have not seen any skeleton growth yet but i am hoping.

These were my only 2 LPS adn lowering the ca has seemed to help.

My heater is connected to a Ranco and it reads 78 and that is where I have it set. Gonna do a good water change and get this tank back in order.

my Ca is 400, my temp. is 78, pH is 8.2, PO4 is .o6 all other corals are fine-so its frustrating as to why this happened to 2 year old colonies.
