Weights in the listings range from about 0.24 pounds to 2.44 pounds. Check the listed weight for each product to confirm it suits your tank setup.

Common color options listed include gray, green, black, brown, red, and yellow. One listing also notes a silvery finish that produces a glow under LED lighting.

Some designs are made to work with an air pump: connect an air stone under the ornament to an airline/oxygen tube and run the air pump; bubbles will rise through the ornament when the pump is on.

Listings typically include full overall dimensions (length × height × width). Example dimensions from results include 6.42 × 6.02 × 3.15 inches and 7.48 × 11.81 × 4.33 inches—use those measurements to confirm fit.

Designs include artificial mountains and volcanic ornaments, including styles that depict an erupting underwater volcano.
