Falconerr it has 3 big rocks as the base and then on top many small rocks arranged in the igloo type island.
Paolissimo im with you about the tangs when i bought them 6 months ago they were tinyyyy but dont worry i already have a 300 gallon tank home for them in the near future.
Here's mine. There is one full tank picture from a few months ago, and a few close ups of new additions. Sorry in advance as a few of them are iphone pics.
