I have a new pair of clown plecos, and need to reshape the tank a little bit to give them more hiding places. They're still small (about two inches) and have only been in the tank about a week, but neither one has really claimed a permanent territory.
How will they use the "pleco caves" that are available? Once they've settled in and have more options to choose from, will they each pick a space and stick with it over time, or will they just grab the first convenient hiding place every day?
