When I travel the fish usually rip apart the plants in their tank. Usually this indicates they are not getting enough food, but these fish are vindictive. They never eat the plants, just tear them up to let me know they are unhappy.
For a couple weeks now their tank has been barren and plantless. Typically I prefer live plants but in this situation I opted for som plastic plants. The green color really enhances the tank appearance. Tried two plants to see how they look and fake plants have come a long way since I was a child.
Try to destroy these plants suckers!
