Shrinking Anemone

Our 32 gal tank where I work -- there is a guy who comes every 2 weeks to service it.

We have the anemone, one clown, and four other fish.

2 or 3 months ago, it almost seemed worrisome how the anemone was such a large size. And I'm sure they can alter their size.

But for weeks it's kept getting smaller, and lately it's reaching a maximum each day of ... I suppose about 1/8 the size I referred to. It seems to be now quite a distance away from the lights.

Is this anything to worry about? I give it small amounts of shrimp and it seems to swallow that. And sometimes a little piece of minnow. I almost never feed it more than once a week.

One factor may be that the service guy I think rotated the rock it's on at one point, so it's kind of facing into a corner. He did this I think partly because the anemone was blocking off an invert from the lights and it was dying off.

Most probable is insufficient light.
About 75% of the Nems nutrition comes from its zoo, processing light into sugars and amino acids for metabolic growth.

What lighting does it have, how old is tank, how long has nem been in?

I keep mine about 3 years now, 14" from 165watt Chinese Blackbox, yup, I too feed weekly.

It's a Coralife Biocube, still having the lights it comes with. We bought it less than two years ago.

We've had the anemone more than a year.

Hearing that it could be over time that the lightbulbs are becoming less sufficient, that has me wondering why it is in recent weeks (shrinking) in effect placing itself several inches farther away from the light. It could also get a lot closer to the lights if it climbed up rocks.

Though if the lightbulbs for instance are with age losing brightness/energy, then maybe the anemone is getting sickly.

Googling now I see there is a fair amount of internet discussion about ways to upgrade that tank including lighting.

Could also have shifted colour if more than 9 months and not LED.
Would likely shift to the red and this can increase algae as well
You never know with Nems, but all require strong lighting

The lights we have, which come originally built in, are LED.

Today I did some checking, looking at my e-mails, and about ten weeks ago the anemone was relatively giant size. Seemed like the definition of thriving.

The owners manual says to wipe down the "light cover" which I now finally did. But it looked relatively transparent to me before wipedown.

I have the same 32 cube with the stock LED's and a RBT that has beed doing great under the stock light for years. I don't feed any more cuz I was tired of the RBT spliting. Lot's of people say the light are junk. I think they are just fine and get good Par readings on the bottom of tank.

I've had this issue with my sebae for years. It goes from about 10"-12" across down to about 6". I used to worry about it but I don't anymore. As long as his color is good and not bleached out. I feed him some shrimp or clam once in awhile but if his color is good, I don't worry about it too much. He's been shrunk down now for about 3 months but I just moved to a new tank about a month ago so I'll give him some time.

If your lighting is not sufficient, in time, he will shrink to nothing.
May take a year or so
