So rare to see a nice mushroom themed tank. I think you can really develop this and have a nice unique focus for your tank. You can get beautiful colors for mushrooms. You should think about some ricordias to spice things up.
They are awesome, divers den. They are 3 hours from my house, and they open to the public 4 times a year. They have stuff there that they dont advertise and 40% off. Well worth a trip.... Amazing
