Hi guys, I picked up a Frogspawn at the LFS a week ago but have yet to see it extend sweeper tentacles. Is this typical? I tried feeding it yesterday by turning off the pumps and shooting some Marine cuisine directly at it. All the tentacles closed up around the food. BUT... as the lights went off the coral started to retract a bit, revealing a balled up clump of food that it was just holding. It never ate it I guess? Is this normal? Thanks!
