aquarium vase decoration

Rinse decorative rocks thoroughly under clean water before placing them in the tank or vase. For artificial plants, rinse and then soak them for 15–30 minutes on first use to relax the fabric and improve appearance; after soaking rinse again, remove any deposits with a soft brush, and allow to dry. Do not use soap or detergent.

Many floating/hanging ornaments use a suction cup plus a thin, nearly invisible wire: attach the suction cup to the tank wall and suspend the ornament from the wire. The ornament's height is adjusted by changing the wire length or its attachment point on the suction cup.

These ornaments (for example, silicone jellyfish) do not emit light themselves but will fluoresce under blacklight, blue or purple tank lights, or other actinic lighting.

Typical dimensions list a base length of about 3.5 cm (1.38") and heights around 6–14 cm (2.36–5.51"). Before first use, rinse the plants and soak them in water for 15–30 minutes to relax the fabric and improve their appearance.

Sizes vary widely: some pieces are about 0.5 inches in each dimension, many items range from roughly 0.5 to 3.2 inches in length/width, heights can run from about 0.5 up to 7.5 inches, and artificial plant heights are commonly around 2.36–5.51 inches.

Silicone jellyfish ornaments are described as suitable for both freshwater and saltwater tanks. Some artificial plants are also described as non-harmful to fish and not polluting the water.

Package counts vary by item — examples include single-piece ornaments and multi-piece sets such as a 10-piece artificial plant pack.

Options include black decorative rocks, dark moss-green faux moss fillers, multicolored plastic plants, and fluorescent silicone ornaments that glow under blacklight, blue/purple, or actinic lighting.
