Neka Driftwood Small
Will work really good with shrimp.
I had never heard of this wood before. I decided to try it out in a desert-y aquascape I'm putting together. Flip sent me a round, semi-hollow chunk (about 6" diameter) with lots of cool gnarls and personality. It looks amazing on pool filter sand with accent gravel, elephant stone and other wood. I can confirm it's dense and sinks fast. Great piece with lots of weird nooks and crannies for shrimp grazing and epiphyte attachment.
