Spiky Gumball (x4)

These are eye-catching seedpods that you wouldn't want to step on but they make excellent baby shrimp shelters. Spikey Gumballs produce beneficial biofilm for grazing fish and release beneficial tannins into the water column. Through decomposition, the gumballs reveal an underlying honeycomb apartment structure. Add 2 per 10 gallons and replace as needed. Boil to sanitize and encourage sinking. Available in quantities of 4 and 8.
