Looking for something to keep your deep sand bed
stirred up? How about some critters to keep your sand substrate free of uneaten food? The following scavengers are great choices. Sand stirrers prefer a thick sand substrate
so they can scour for organic foods.
Please note: If the sea cucumbers are attacked or injured, they may expel their internal organs, which can be toxic to fish. In the wild, they will regenerate those organs, although this regeneration rarely occurs in an aquarium setting.
