Black Carved Lava Rock - Large

Lava rock in general is one of the best rocks to use in a shrimp tank. Lava rock is extremely porous which provides tons of surface area to grow biofilm and beneficial bacteria. Lava rock  will create natural feeding grounds for shrimp and especially baby shrimp. 

Black carved lava rock is ideal for an aquarium because it adds character. The holes add depth to the aquarium and provide natural decoration to include in any aquascape. 

Our large black carved lava rock is around 5-6 inches per piece. These are great pieces for a shrimp tank. 

Key Benefits

  • Will not increase Ph
  • Provide natural feeding ground for shrimp and other algae eaters
  • Provides hiding places for baby shrimp
  • Beautiful texture for aquascaping

For best results we recommend rinsing rocks before addition to an aquarium. Although all pieces are cleaned, it is natural for rock to create additional dust during shipping.

You will receive one (1) hand selected piece of carved lava rock. Each piece is inspected and packaged with care to help protect the character of each rock.

*Each piece is different. The stones you receive will not be identical to the product pictures although are accurate examples of what you will receive.*

My shrimp love it

Literally! My shrimp love it! If they aren’t deep in their pilo moss jungle then they are in this rock. They have plenty of plants and another lava rock cave but this one here is the one they prefer. The glue that was used to put the tag on it was annoying to take off but luckily that side went nicely facing down. Haha don’t judge, i know it looks messy but I gave my shrimp a wild jungle side for them and a nice aesthetic side for me and they easily cross over from one side to the next.

Nice piece of rock

Wanted some inert rock work for my shrip/fish tank. This fit the bill. My Stiphodon Goby has claimed it as his castle.

Good quality as always

Always loved the lava rocks y'all have. Got this one for my mother's shrimp tank and it's perfect.

Significantly Smaller Than Advertised

I had hoped to use this stone as a central piece to a 4gal cube fish tank and this rock was significantly smaller than advertised. Hopefully I can find a different application.
