Features

  • Charming Aquarium Decor: Imitating the real sea urchins, the appealing rainbow ornament turns your tedious fish tank into a lifelike ocean landscape.
  • Glow Under Extra Lights: The rainbow decor can't be luminescent in the dark but glows under actinic lighting. Great for brightening and invigorating your plain aquarium.
  • Stable in Water: Designed with a strong resin base weighing 4.4 oz, it always stands stably in the tank when the rainbow needles swing with the movement of water.
  • Reliable Material: Its made of soft silicone material, which causes no threat to your fish and is dependable to keep them lively anytime.
  • Easy to Use: Measure 2.3'' D x 4.3'' H. Just put it into your fish tank and it will always remain realistic looking. Fit for both fresh water and marine aquariums.

  • Worth the money
Color: Rainbow Sea Urchin
Great it’s as pictured and has the glowing effect with blue light the base is heavy enough where you don’t have to bury it in the gravel and it’s pretty big as well I was expecting a small one pleasant surprise

  • Cute Halloween aquarium Decoration
Good quality aquarium Halloween decoration, my goldfish seem to like it as they occasionally go inside the pumpkin. It’s a good size, about 4.5” wide and 4”” tall, approximately. Cheaper price than I have seen online elsewhere.

  • Nice pumpkin fish tank decor
Haven’t put it in the fish tank yet but seems reasonably thick, pretty good color, wish it we’re a bit darker orange but looks good, price came down a bit so had to jump on it. Maybe 3D printed? Pretty dope, excited to put it in my fish tank for fall/halloween. Nice size, not small but not to big. Will go in a 30 gallon fish tank. If in some way it goes the 2 months until after the season when I take it out without discoloration/fading, or algae build up that can’t be removed then I’ll upgrade to five stars on that bad boi. ... show more

  • Aquarium lifelike addition
Color: Rainbow Sea Urchin
It looks great in my aquarium. The fish love it too. My mystery snails keep it clean. It is also very easy to clean as well. It will brighten up your tank! I am very happy with my purchase.

  • Love it in my aquarium!
Color: Skull Reptile House
Perfect size for my mature Mbuna cichlids to use! I did sand down some of the edges as mentioned by others as some were somewhat sharp from the molding process. Just what I was looking for and perfect for my 55 gallon!
