I have a columbian zebra pleco that has never seemed to move from a spot on a piece of driftwood. I would like to change the tanks its in but can't because this little spot also happens to be almost a little cave that i think it ate a hole into itself (idk its under the driftwood) I can't move the drifftwood to the other tank as the anubias planted on the driftwood is WHY i want to move the pleco so how can I ge tit off?
