Gave the tank a pretty thorough cleaning today including removing and scrubbing the rock. There isn't a lot in there to begin with, but the undy absolute freaks out without a hiding spot. So I dropped in one of those generic logs you can buy at any number of pet stores.
Got everything back into place, and the undy won't let go of the log. Refuses. Every time I try to get the log out, it rushes to the log and locks in. Took the log out, put it in a bucket...no sale. Hangs out in the branches and just lurks...peeking out from behind the branches only showing one eyeball.
So it gets to keep the log. Not much for saltwater decor, but a happy fish is a happy fish.
