I get the home made food from Archit.Every other day I put a small piece in with 2 cube of Mysis and I get the same response as you.My acros only response like that only when I use Arhit's food
I get those long white strands on the underside of a tabling frag I have. At first I thought it was being attacked by bugs but it does it when the sand is stirred up or there is food added.
