Review: Good amount of rocks for the price and nice quality, identical to photos. Came nicely packaged and adapted quickly to my tank. Highly recommend for larger tanks (20 gallons and up) due to the large proportions of the rocks and amount of rocks you get 👍
Review: Color - tanish and mostly the same color. Size - Perfect! Multiple sizes and one or two just right Looks - Cannot explain the beauty. They shimmer in the light. Almost like they’re glittery at angles. I was wondering why these rocks were the most expensive compared to the other products they offered. I’m not regretting my purchase. If you needed any validation, these rocks make me want to steal rocks out of mountainous state parks! lol I have learned that’s illegal so I won’t but dang it these rocks are worth every penny! I’m sad to see they have limited stock as it’s not in my budget right now but I’d love another box for this tank or another smaller one I’d center these for a single island in a cube tank. Note: when viewing the photos, note there will be a Java fern there later this week.
