Wall-building is a typical behavior for an Odontodactylus (several species) attempting to construct a burrow. THey will build a wall next to another object, or two walls parallel to one another. In the process they wil deepen the trench at the base of the wall and then roof over the top creating a burrow. It often appears that evolution has selected for behavior that utilizes the concept of a Keystone.

well chuck the wall building idea to the scrap heap it appears to be instinctual. I would still like to see video of this behavior if you have it

hes never slept behind it or on it. his burrow is actually on the other side of the tank.

i took down his wall and this morning it was back up.

he was very upset it seemed. was putting a few rocks back in place and when he saw that i was looking he would set it down, turn his body and then use the ....appendages under his tail to kick up dust and shoot the rock against the glass

The fanning behaviour using the pleopods to shift sand is the trenching behavior I mentioned. Bigger material that can't be fanned away is then picked up using the maxillipeds.

well looks like i wont be posting vids, woke up on sunday and Thing had passed in the night.

checked water perams and they were pristine. checked for possible stray voltage, nothing.

had him for 2 years and i got him as a full adult so im guessing it was old age.

Thing, youll be missed.
