Awesome Aquatics Natural Cholla/Choya Wood 3 Pieces 6†for Shrimp habitat and food treat Hermit Crabs Plecos Aquarium Decoration Lowers pH Hideouts and Chew Toys Reptiles Thorn Free Dried Organic

Adds beneficial tannins to the water. Be careful and make sure you seal the big holes at each end if you have smaller fish. They can get stuck inside. Other than that, this is good quality cholla wood.

Good for shrimps, but a a lot of money for what they are

i have a few of these in my tank and my shrimp and snails love them. i added a few live plants to each piece and then put suction cups on them so they could help hide heater and filter. well worth the money, i was happy with the sizes of each piece. will buy again

I boiled the cholla wood for 5 minutes, then soaked for couple days to reduce the amount of Tannin. Water still browned but provides great hiding place for my shrimp!
