I received this cool new "rock" from my good friend at Eshopps. Those guys never stop thinking of ways to make the hobby more enjoyable, all the while keeping it affordable. The frag rock is a 3.5" diameter realistic looking artificial rock that holds up to 5 1 7/8" frag plugs securely. Just looking at it for a few minutes today I was able to come up with a dozen different ways I'd use it. 5 plugs with different colored zoa's and paly's would make a cool little garden Stuff the holes with Xenia of different types and cover with veil would make a nice island. A tall branching LPS like some type of Euphy in the center and surround with zoa's Those are just some of the ideas that came to mind right away. This artificial rock is well thought out and will quickly be inhabited by colonizing microbacter, becoming a part of the natural bio-filtration. The surface area is textured with many small and large pores and is colored to resemble a mature rock allowing it to fit in with your aquascape and not stand out like a sore thumb. The bottom of the rock is dished with a level 1/8" rim around the circumference and it is heavy. These features will give your frags a solid base that isn't going to be disrupted by sand sifters or flow pumps. The top side is beveled so that your frags will be at a good viewing angle. The one issue I have with it that it is almost too round and hockey puck looking. But still I'm happy to have it and look forward to the time when I get to fill it with frags. This is going to look great when in my new build. I'm thinking I'll do the zoa garden with it.
