Acan feeding issue?

[lilbitreefer]

So I recently picked up a tank from a guy getting out of the hobby.It came with 2acans. I have noticed they do not have much of a feeding response. I am used to acans grabbing large meaty foods like mysis. I have been spot feeding reef roids and polypbooster(before reef roids).I think they were a bit neglected. (Fungia was bleached but still alive, and still alive today!) they all are taking in the reefroids with mucus but there is no tentacle extension and mysis just rolls off them. I am having the same problem with all the lps from that tank as well. Any thoughts? Do thy just need to heal up? Both acans are beginning to color up and are puffy as well. Not sure what to do. Acan bottom right.

I would let them settle into your tank a bit if they are not eating large foods. Hopefully, they will recover and start eating again. I've had a plate do the same thing when it wasn't happy. Eventually, it puffed up and eats what it can catch now.
