10 Best Fish Tank Ornaments 2024 | UK Veterinarian Reviewed

This simple and understated fish tank decoration is one of the biggest selling and most highly rated ornaments on Amazon. Over 2,000 people have left customer reviews, the vast majority of which gave five-star ratings. This moss-covered piece of driftwood is actually made of durable, water-resistant resin that won't disintegrate or fade in fresh or saltwater. 

This ornament looks totally natural and allows fish to feel at home, but unlike a real piece of driftwood, it doesn't run the risk of introducing parasites or snails into the tank. Fish can swim around and under this rustic log, as well as venturing into the dark hollow space inside for some much-needed calm and tranquillity.

We think this cheerful selection of favourites for under a tenner is a great pick when decorating a home aquarium on a budget. Not only do you get the classic barnacle-smothered shipwreck, but also some brightly coloured plants and glowing pebbles too.

These would suit a smaller fish tank as while the sunken vessel is 15 cm in length and 11.5 cm tall, the plants are a little smaller. The luminous stones can simply be added to the tank floor for a pop of colour, even in the dark. 

We adore these kaleidoscopic, magical looking jellyfish ornaments which float in your tank and create an exciting, vibrant tone. You will need a fluorescent blue fish tank light (which most tropical fish owners already have in place), to achieve this cool effect. 

As long as you add some texture to the floor of your tank (including places for your fish to hide away when wanting privacy), you may not need to add much else as the colours and shapes of these decorations make such a striking statement. 

This skull ornament ticks quite a few boxes. It provides a rugged aesthetic, reminiscent of childhood pirate stories as well as some pretty fronds of pink and green seaweed, to help fish feel like they're in a natural ocean environment. 

The skull is also hollow and ideal for hiding, so it could be good for calming stressed fish. The polyresin is durable, easy to clean, non-toxic, and of course, safe for fish too. This item would suit a small-to-medium tank as it measures 13 cm across and 14 cm high, and has lots of positive feedback from reviewers.

This set of Spongebob-themed ornaments is a brilliant way to add some fun architecture and peaceful hiding spots to your home aquarium or tank, as fish can weave in and out or find some calm inside each hollow ornament. 

The resin used is hard-wearing and fish-safe, perfectly designed to survive in either freshwater or saltwater. These items are best suited to a medium or large fish tank, as the largest measures 16 cm in length. They might not be a great pick if you have no idea who lives in a pineapple under the sea, but they are great fun if you do!

This 13-piece set is aimed at a medium-to-large fish tank, with a capacity of between five and 15 gallons. You can deck out your entire tank with glorious, flourishing faux-plants that fish can hide behind to feel totally at home and display natural behavioural instincts. Each item has a heavy pedestal at the base to help it stand firm.

The water-resistant silicone they're made from is entirely safe for fish and designed to survive underwater with minimal damage. Do remember to add some real plants to your tank too if possible, for extra happy fish.

If you love the character of Crush the turtle in the Finding Nemo film, you will want to add this model  to your tank. The officially licensed ornament is part of a collection, so grab Dory, Marlin and, of course, Nemo to complete the set.

A few shoppers have noted that the paint had begun to fade after the turtle had been submerged for a couple of months, so we've kept this product a little lower in our ranking. It's also a little on the small side at 6.4 cm in both length and height, so it will need to be teamed with other ornaments to fill a tank floor.

This bubbling tank ornament is one we think that you and your fish will both enjoy. It is designed to sit over an air stone (sold separaetely) to create a thrilling pattern of bubbles, but it also comes with LED lights built in for a party time atmosphere!

The resin model is intended to sit over the top, allowing the flurry of bubbles and the gently changing colour display to burst out of the volcano together. Just note that the actual air pump is not included and must be purchased separately, moving this option down the rankings.

For Marvel fans, this friendly resin Groot could be a pleasing addition to your fish's habitat. Air bubbles shoot up out of his leafy hair if you connect him to an air pump (not included). As you'll have to buy a separate air pump, this ornament is further down the rankings.

Groot might not be as much of a household name as some other Marvel characters, but his tree-like appearance does make him more rustic, so he won't clash with plants or more naturalistic wood-look ornaments. Perfect if natural and tasteful is what you're going for with your fish tank design. 

For a novelty addition to your fish tank, why not consider this chest of sunken treasure with a resin diver making an exciting discovery? When attached to an air pump (which is not included) the lid of the chest opens and closes and the diver floats up towards the water's surface, appearing to drag the chest open as he goes. 

Certified fish safe and non-toxic, this unusual ornament adds movement to your fish tank and a fun narrative too. Certainly more interesting for your fish than the end of  a regular air pump, but as the pump isn't included we had to move this one down the rankings.
