Porous Lava Rock
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.
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.

The carved lava rock adds a natural look to my shrimp tank. The holes are perfect for baby shrimp to hide in. I’ve noticed more algae being eaten and the water seems more stable. Rinsed it before adding, and it’s been in the tank for two months without any issues.

Great for aquascaping. The texture is unique and the porous surface helps with bacterial growth. My shrimp are more active now, and they seem to like the nooks and crannies. A little dust after rinsing, but that’s easily cleaned.

I bought this for my nano shrimp tank. The carved design fits well with my setup. It doesn’t change pH and provides good hiding spots. The biofilm has grown nicely, and the water clarity has improved.
