Asian acan dying.

[Notsolostfish]

Anyone knows why my asian acan every night around 6-7 pm. It shrivels up, opens mouth and expelles brown lines. At first i thought its pooping. I had it for around 2 months.


That’s my parameters below. Tank is 11 months old. Everything is thriving.

That's normal; its just pooping like you said. As long as you don't see any recession, then you're fine.

This is my first time keeping asian acans. And so far i heard mixed answers about it. One being they like cooler temps. My tank is at 78 most of the time max 79 in hot heat summer. Ill keep my eye on it. I found it odd its been doing it dailt. And even during day time its not as big as it used to be.

Are you feeding it daily? If it's doing it daily and you're not feeding it daily that's abnormal.

I am not feeding it daily. But i feed the tank lrs frenzy. And obviously corals get some while at it so I wonder if thats the case

Maybe. If it's shrinking, that's not a good sign. Have you seen any skeleton exposed yet?

Looks like poop coming out. They can take a day or two to digest what you feed

That looks like it might be expelling zooxanthellae, What kind of lighting is it under, do you have any measurements for PAR and whatnot? Has there been any recent change in the light intensity or schedule? Has it been moved lately to a higher intensity lighting area?

How long as it been spewing brown stuff, since you got it or only recently?

I got this acan around 2 months ago. It was doing great even growing a second head at the back. My lights schedule never changed nothing. Its been in the same spot i got it in.

I would say it has been spewing brown stuff roughly if i remember correctly a week? Maybe less than a week. Not quite sure. I tested my oar a while back. And while i dont have the exact measurement for that specific spot its under 100 par.

Definitely hard to say then, that amount of light shouldn't be an issue. It could still be zooxanthellae in a totally normal expulsion - sometimes even my older corals will puke out a strand every now and then. The shrinking is worrying though. I'm afraid I don't have any other suggestions with your parameters looking so nice.
You might be in 'wait and see' territory.
