Panther crab tank

[Plant-master]

Hey every one, I have just set up my 20 gal long for some Panther crabs. There is some chicken bone stone and some sand for them but I want to make this tank look better. I know that they will eat plants so I wanted to put i water lettuce in. But what can I do to make this tank look less bare?

if they eat real plants they sale artificial silk  plants that look real nice or a nice piece of wood  or add fish decorations or tunnels or caves my first pelco ate plants and  I just had silk plants , wood and a few decorations for 13 years

Nothing too tall unless you have a lid. I hear they are escape artists. I love this idea, keep us posted!
