A couple weeks ago I rescued 2 exlarge pp's that I am looking for things for them to climb. I have wood but they prefer plants. Artifical ones aren't strong enough to hold them. They literally pulled my humidifer wand and tubing off the wall and are always found in the morning wound around the plants. Suction cups don't hold them. What do you guys with larger crabs do for climbing things for this sized crab? Right now they are in my 75 gal tank with 4 medium pp's.
