Acans die

[iNTEL]

Hello… Happy New Year!!!! Hope all is well.

Question: what water chemistry can affect acans and cause them to die.?

I have had two different acans died and one is slow on the way out. I have two more that seems to be doing okay. Tank is about 4 months old. 10g

Appreciate your time and advice. Thanks

Some are:
High Phosphates
Too much light
starvation ( feed mysis shrimp)
Low salinity
insufficient lighting
Inadequate water flow

Any fish you have that might be nipping? I can't keep acans as they seem to be a delicacy for naughty fish.

I had 10 acans in my tank at one point, every single one of them died as well as lots of other LPS got unhappy when I start using gfo to lower phosphates In my tank.
(I might have over used gfo during that time.) In a way started my corals, I guess.

I agree, I had a supposedly reef safe Cherub Angelfish that just loved to peck at my acan

Most of those checked out to be okay other than phosphates, which I need to test for. Appreciate the advice.

currently I only have two clown in the tank and small clean up crew. I have not noticed the clown nipping at anything.

Currently no running GFO, but have to test for phosphates.

Thank you all for your suggestions and advice.

I would recommend posting a full set of your parameters, that way folks can post some solid advise.
In general, that’s kinda the first step.
Acans, are typically pretty hardy, if your acans are dying, something is off but hard to say without knowing where all your parameters are at.
You mentioned your parameters are ok but that is very subjective.
I tend to neglect my tanks during summer, just busy doing outside summer stuff.
I don’t remember ever having issues with my acans, mine seemed to like a little dirty water. lol!

Acans are one of the corals I always gravitate to. Over the years my tanks have always been over 9kh but I have tried changing a lot of other variables and have found:

They handle high light if acclimated much better than low. I have some at over 350 par.

Flow needs to be medium to low.

They do not seem to like high (over 200ppb) phosphorus.

Peppermint shrimp love to eat them.

Algae will take them out pretty quick if it gets on their skeleton.

Other than that they seem to tolerate a lot of abuse and grow fairly quick.
