Is it possible to overfeed an octo? I'm sure it is, but how do I know what is too much. Will an octo eat if there is food in its tank, but isn't hungry? We feed Alice 2 good sized bait shrimp a day, or vary ir with a shrimp and a crab, but sometimes she will act like she is hungry very soon after eating. Just wondering. She's a big octo, and maybe she needs more food. What do you all think> Funny side note: When she has finished eating a shrimp or crab, which she always eats in her den, she will bring all the shells out and deposit them for pick up (by us) in a specific corner of her tank. She has kept all the shells from the clams in her den, however.
