Good product
This is actually much larger than anticipated. It won’t work for shrimp as fish can also get into it.

This is so cool five stars all day long 🥰
This is so cool!!! I had a glow shark probably 4 inches long and it absolutely loved hiding out here. First time I seen him in there I thought it was going to get stuck. ðŸ¤ðŸ¥°

Wouldn’t buy again
Great idea, but my fish and shrimp don’t use it. It just collects waste.
