How to choose ship decorations for an aquarium

The most important thing to consider when choosing a sunken ship decoration for your aquarium is the safety of your fish. For this reason, you should only use ornaments that are specifically designed for use in aquariums.

Think about the kinds of fish and animals you keep as well. Most sunken ship decorations have great caves and holes built into them that shrimp and small fish love to hide in. Try to choose a decoration that has holes large enough for your pets to swim into safely, without getting stuck.

Choose a decoration that fits into your tank with plenty of room to spare, so that your fish will have space to swim and play freely.  Once you’ve bought your new decoration, have a careful look for any sharp edges that could hurt your animals and file them down until they are smooth.

Once you are sure the decoration is safe to use and fits in your tank, it’s time to let your imagination run free and create a mysterious underwater world. You can choose a design that fits your theme, and there are many to choose from, like:

Use your creativity to make your aquarium just like you want it to be. After all, there’s nothing better than having your own unique underwater scene.

You can use rocks to create a shipwreck on a reef type of scene and plant small aquarium plants like anubius nana around the ship to look like seaweed. You don’t have to have the ship flat on the ground either, you can get creative and set it on top of some rocks or have it facing straight ahead.

Many sunken ship decorations come in two halves, and growing taller plants like java ferns between the two halves can create a really cool look. You can use a great stick-on background on your tank to add more color and depth to your aquatic world.

One technique that looks really cool is to place an airstone (connected to your airline and air pump) in a hole in your sunken ship decoration for a really interesting effect. You can use natural-looking sand or gravel in your tank or let your imagination run wild with something more colorful.

Frequently asked questions

How do you clean sunken ship decorations?

Over time algae will begin to grow on your aquarium decorations. This can look really cool on a shipwreck ornament but eventually, you will want to clean it off.

Clean your decorations when you’re doing your regular water change to limit the disruption to your fish and use something like a soft brush to avoid damaging the paint job on your sunken ship ornament.

What should you do before putting a new ornament in your fish tank?

Before putting a new ornament in your fish tank, check for any sharp edges and be sure to smooth them out with something like a nail file or sandpaper.  Now it’s time to wash your new sunken boat decoration in warm, but not hot water. To be extra safe, leave your decoration to soak for a few days, changing the water every day.

Can you grow plants on a sunken ship decoration?

You can grow plants on your aquarium decorations and this can create a really unique and attractive look. Before doing this though, remember that cleaning your ornament with a plant attached to it is going to be more difficult.

There are two ways to grow real plants on a sunken ship decoration. You can use a plant like anubias nana or java fern and glue or tie the plant to the decoration using fishing line or an elastic band. The other, easier way is to put the plant in its pot just behind the decoration or in between the two halves of decorations that come in two pieces.

Do bettas like ship decorations?

Bettas love decorations, especially ones with caves and holes that they can explore and hide in. Before putting a new decoration in your betta tank, make sure that the holes are big enough for your fish to swim through without getting trapped, and that there are no sharp edges that could damage its beautiful but fragile fins.
