I gave her a piece of shrimp that night, but kept the bubble.
Woke up to an intact bubble - so we let the crab out and she got it.
Last night we put a crab in a clear jar - no lid.
Ambushed it twice and sulked off butt hurt, no other interaction.
This morning the crab was still alive. We left it in the jar and fed it.
Offered her a different crab via chop sticks, waved it around the tank, dunked it into the open jar a few times to show her it was open, then offered the new crab - she ate it.
She came out around when we got home 8:30pm - really grasping our patterns now.
The crab was still in the jar. She did some exploring, snuck up on the jar, but no real interaction, touched the glass a few times with an arm, but no real attempts were made to get the crab.
Explored the tank a little, stood up on the conch in the corner of our tank by the yellow plant (she likes watching us from there) and threw the crab body shell (from breakfast) at me.
I think she is pissy about the crab in a jar - and is demanding more easy meals, haha.
We left the fed crab in the jar again tonight. It is only a matter of time before she figures it out
OOh also, almost forgot, today is the 3rd time we caught her up on the glass near the top of the tank. Once, she seemed to be investigating the small panel of glass/lid near the overflow. Second time, opposite side of the tank, possibly looking to flush out the lone peppermint shrimp. And a 3rd on that same side of the tank "watching TV" or Rocco.
