Acan closing up

[Mr.Rocc]

My acan was beautiful and plump last night and now it seems to of closed up. Is it a flow or lighting thing or is it normal. I've read about it being both.

 

[Mr.Rocc]

O and my parameters are 0 ammonia and nitrites, 5ppm nitrates, 8.0 pH, 410 calc, 1200 mg, 9.8 all 78.3 temp, and 1.025 salinity

How new is it? Mine didn't open up for a day or two.

 

[Mr.Rocc]

A little over 2 weeks it's open huge and plump this morning then around 6 it was closed up

You can try moving him up on to the rocks slowly. I know they like low to mid light, but mine is perched on the top of a rock and seems happy.

 

[tdiddy]

Just note, it might take it a while to open up.

what kind of fish you have ? mine did same thing and it turned out it was my hippo tang nipping at them

 

[Mr.Rocc]

One clown and that guy is nowhere near it when I look but I might just not be seeing it. I'll keep that in mind @Anthony kolodziej

To be honest sometimes mine will close up for no reason and then be open and fine a few hours or days later

Mine are healthy and creating new polyps, but they tend to close up for a day after I “direct” feed them.
They take the food and seem to like it, but the day after they are totally closed up
