Chalice Sweeper question

[m and m]

Before I went to bed i just wanted to throw a question out there to see if there was a answer. I feed my chalices regularly 2-4 times a week. In my old tank there where a few pieces that had 2 inch pluse sweepers now in this tank they barly come out, matter affect the only sweepers that do more then poke out are my fevias is there a Parameter issue this could be related to? Or could it be they still have only been in this tank for 2 months so there adjusting still? Everything still eats when food is placed near the mouth just no crazy sweepers like i use to have.

I had the same thing happen to alot of my chalices since I moved them and had to add a lot more water to fill the new tank.

Perhaps you have better flow in this tank and the sweepers don't extend because of it?
