Acan Emergency

Man that sucks! Sounds pretty wierd don't have a clue just hope that crap dosen't happen to my new acans! Sorry man.

 

strontium levels ok? Sometimes corals can let go of their skeleton when lacking strontium.....though rare it would do it that rapidly, to multiple acans. Any other stony corals in the tank?

 

and forgot to ask....water change recently? Ro...tap.....top off...change in salt brand..?

 

I had that with my Acan, It's still alive luckily and it might be strontium idk, calcium is fine, Would it be Alk related prob?

 

Just curious what type of lighting and where in the tank the acans were placed. Also were these wild caught? Some times the corals can get shell shocked if there wild caught or if there placed to high in a tank with halides. Could be so many things its hard to pinpoint.

 

t-5's and they got moved to higher flow and lighting area to try and help. They were from a tank culture

 

mine just shrunk after a few months, one or two and they used to be big and pretty

 

I would think if it were shell shock it would have happened a lot sooner. It sounds more like something ate them. Someone was saying something about pepermint shrimp eating acans on a post a few days ago do you have pepermint shrimp?

 

Are you feeding them and what are you feeding them? I have found that some don't do well unless they are fed.

 

I have had mine for about a month and they eat the cyclops and other coral foods I add to the water column and I already have new groth.

 

IMO they need to be target fed. Some seem to do fine without it but others don't. Lord, mysis should be good but I would not rely on just the water column. I feed Coral Frenzy mixed with Cyclopeze and use a feeding tube. I have only been growing them for about a year but that seems to do fairly well but I would like to see better growth.

 

Yes I do, but in your case it sounds like you have been feeding. My guess is in your case something missing or an abrupt change in something. I had an acan do what you describe once and I have no idea why. Sometimes that just happens.

 

You didn't say what your calcium level is. I had frogspawn do the same thing and found the calcium level very low. Not quite the same coral but I would check anyway.
