Well i haven't seen him spit any food up and i've been watching him for at least a half hour for feedings. I also check on him periodically through the day.
However, this morning I found him upside down in his cup... Since the Clarkii's can't get to him I assume he made this move on his own. His foot was flat against the mesh and he was partially closed. Not a good sign at all... I'm becoming very worried that I won't be able to help him
He's right side up again now, but his foot remains unplanted. He's kind've a little tumble weed.
