I bought a nice (large) heliofungia at the LFS
today. I'd been eye-ing him for a week, and I took him home today. He wasn't the healthiest looking one there, but he wasn't unhealthy. When happy, he's a nice swirl of metallic purple and metallic green. His tentacles weren't as inflated as much as the other helio's were. Anyways, brought him home and wanted to see if he would eat. He got a bit of silverside larger than I wanted him too, but he shuffled it to his mouth, opened it RIGHT up, and devoured a full-sized silverside. As of right now, his mouth is closed, but visibly raised over the rest (that piece was large) and he's ultra-inflated, with his tentacles fully extended and gently waving in the water. Seems very happy, and so far, I am too.
