willem.....the grass looking thing is a 14"x14" pad, plastic mesh hidden under the rocks with the "grass" coming up out of it.....about $15 at petsmart.
the other plants are also plastic and they're burried pretty good and in corners, they seem determined to dig up the pad so they haven't messed with the others yet.
they fight sometimes.....and sometimes i hear some serious water moving around when in another room......it all boils down to the food chain
