I like this rock because it is colorful and provides a great space for smaller fish to hide. I like to put a small air bubbler under this and make the bubbles come up through the hole. It looks neat.

Pros: looks nice

Cons: none

I thought this was a little plain for my tank, but the fish did enjoy swimming through it.

Pros: Fish like to swim through

Cons: Not as pretty in the tank

I used to have one of these in an old fish tank. The fish like to use it as a hiding place as well as a little swimming hole to swim through.

Pros: Easy to put in tank

Cons: none

Wonderful pc to add to any tank. It looks realistic and fish love to hang out and swim around and through it.

Pros: beautiful

Cons: none
