Wellso shrunk up

[Acro_holic]

I've had this great rainbow wells for 3 or 4 weeks now. For the first 2+ weeks it looked great. It was huge and colorful. One day it got really puffy like a softball and then then since it has looked shrunken. I?ve never seen any tentacles at night to spot feed though I?ve been looking for them. Anybody knowledgable about what makes these things tick?

21 inch deep tank - AI Vega 8 inches off water- Placement is front and center on the bottom.

Alk was a little low 7.9, Nitrates a little high at close to 20 which doesn't surprise me since I just added back fish from QT. Ca was 455 and Phos was ok but don't remember the number. I had the LFS run the tests. I need to test these myself going forward.
I'll do a large water change this weekend, I'd bet these parameters being off are the issue.

Joc - I bought krill but I've been waiting for the tentacles to reach out supposedly during the nighttime. I haven't seen this yet and it won?t grab like it is.

If your tank parms are good, then you have some one in the tank that is pecking it.
