Hello all!

Number one, this is NOT a question of "how big will they get" - I know how big, I've had them before.

This is more "behavior" related. I got my TTE when he was small (obviously) and he naturally made his home in one of my ornaments (large driftwood-style resin, has some openings). Now, he is over a foot long and at least 1/2" thick. I *never* see him out of there, but he does stick his head out to snatch nightcrawlers. I was *extremely* concerned that he might have grown too large to be able to get out. So I shifted the angle of the item yesterday, to expose the largest opening (that I know about) on it - the bottom part of one of the "roots" - he also often sticks his head out of there to snatch nightcrawlers. Upon shifting the position, he decided to partially come out of the bottom hole, and I was able to coax him out the rest of the way by wiggling a thin brush around inside from the top opening. So he was out and safe.

So I re-positioned the ornament again, this time burying the bottom front opening "securely" in the sand. He was swimming around fine, and I though he had found a new home for himself among some rock caverns I have.

This morning I wake up to see that bottom front opening dug out, and he's back in, with his snout peeking out from the bottom. ..... <sigh>

So bottom line, my question is, are they smart/dumb enough to know when they've grown too large for the home they have made? Will he realize (beforehand) that he will (at some point) no longer fit through the opening he just went back into?

There is NO way he will even be able to have his body itself inside, when he gets to 2', let along larger. Will he realize, when he can no longer move around inside easily, that it might be time for him to vacate it?

Thanks!

(If necessary, I can post pics of the setup)
 
I have heard of it happening with Catfish and Plecos - those are spiny and chubby making them get stuck easily. However eels can squeeze through the tiniest of holes and spiny eels are laterally compressed making it even easier for them. I wouldn't worry about it - however for peace of mind you might want to remove the ornament like Travis said.
A bigger concern for me would be him burrying (like you mentioned in the OP) and it falling on him.
 
No worries on it falling on him - that whole section of the "stump" where the bottom front hole is could be exposed with no chance of the item shifting position. I was not sure how much they can squeeze themselves through - I think that's more what I'm concerned about - him getting to fat/thick.

I may pull it out and use some aquarium adhesive to make the openings smaller (too small for him to get back in, but still allow for air bubbles to come up through.

In the 1st & 3rd images, you can seet top upper opening where he often pokes his snout out to snatch the nightcrawlers :)
 
Ok, so I decided to take it all the way out. Not only found BOTH eels (Tire Track & Fire) in there, but also my Reed/Rope fish too, lol. Found out the resin is wearing and it actually cracked a piece off. So, since they're both now safe in the tank, I'm off to my LFS (specialty, NOT PS/PC) to get some real driftwood & lace rock to basically re-create the structure (I sent pics of it to the store manager, who I've dealt with before) - he said he knows the piece and he has stuff in stock that will work great :)

Will post a new pic when I get all the new stuff situated :)

Just a suggestion for driftwood, you can check out a nearby river or lake and grab some pieces there. That's what I did. You just want to bleach it, rinse it really well, and then put it in the tank.

I have had a tyre track now for 3 years in a 570ltr tank, he has always lived in an ornament, he loves it, he is now long as my arm, so I'd guess just over 1m in length, I think once they get set on a safe place to hide, they love, regardless of how big they get
