Harry Sanderson –
Added a few lotus seed pods to my shrimp tank and noticed a natural blackwater effect within a week. The shrimp are actively feeding on the biofilm that formed. The pods look beautiful and don’t disintegrate quickly. A great addition for a natural look.

The pods arrived dry and intact. After a few days, the water turned slightly tea-colored, which I love. My small fish use the hollow structure for hiding. No issues with water chemistry or fish behavior.

Perfect for a minimalist terrarium setup. The pods add texture and depth. I’ve seen increased activity among my shrimp and fry. No adverse effects on water parameters.
