PLASTIC SHRIMP SHELTERS, MADE OF PVC, GREAT HIDEOUT FOR BABIES AND JUVIES. THEY ALSO GROW BIOFILM/ALGAE IN THE CREASES. QUANTITY 10
I wasn't to sure what to expect. Upon initial introduction they floated. After a few days they began to sink. I like the white as I can see the algae begin to build on them. I have also seen a sudden boom in baby shrimp in the tank. I do not know if is the inclusion of these balls in the tank but they definitely add a place for shrimplets to play and be safe.
I stumbled upon these tiny shrimp balls during a google search and buypetshrimp was the only place online I could find selling them in the US. They are a perfect size for tiny hatchlings. They lay in the wrinkles and the balls seemed to have a little one in every wrinkle! I am so glad I found them.
