Aquarium themes

[Avarswiel]

My fishtank has a natural theme to it, cuz its a saltwater tank and it looks so much better as a natural tank. Plus i'm to nervous to put pretty painted objects in them. Its got a couple of lave rocks in it, and some marble rocks, couple of shells and bits of coral (not live) here and there. with sand at the bottom of the tank

I always wanted to use sand in my freshwater tank, but I did not know if it got sucked up when you use a gravel vaccume...and I would not give up my gravel vaccume cause it is my life saver sometimes sweatdrop
