oh. never mind about the previous comment!

its interesting and a great idea!

This gets better and better, impressive!

Nicely done, also the black ones do better as you dont' see as much of the PVC that way.. BUT you also can't see a dark fish in their either.. These are great to have as they don't take much room and are light weigth so NO water displacement, as in using reall rocks..

what glue did you use to stick the rocks? I look neat! Do you have picture of it in your tank, do this fish like it? Sorry I have way too many questions!

I couldnt find the black pvc pipe I looked for it. I used aquarium safe silicone to glue the rocks on.I do have a pic of it in the tank that I will post for you. As for the fish I dont know if they like it yet because I havent added fish to my tank yet I just set it up.

Looks interesting,you are creative! that woul go well submerged on white sand..
