Artificial Plants for Goldfish


Goldfish like artificial plants in their tank, as they provide hiding places. Live plants can also be beneficial, as they provide oxygen and help to remove nitrates; however, you want to be sure to get a type of plant that is safe for goldfish since Goldfish will likely try to eat them.

If you want a more natural look than plastic plants, there are artificial plants made from silk available for purchase online and at most pet stores.

Goldfish Tank Decorations

Goldfish like decorations in their tank. It’s important to provide them with plenty of places to hide and explore, so they don’t get “bored” or feel unsafe. Some common items that people put in a goldfish tank include live or fake plants, caves or unique themed decorations, light-up decorations, and background inserts. They also enjoy hanging out in flower pots or other homemade DIY decorations if you’re not interested in adding kitschy fish store decorations to your tank.

Goldfish like tanks with good aeration. This is because they come from lakes and ponds where there is a good amount of oxygen present in the water. Most store-bought pumps just won’t provide enough aeration to an overstocked goldfish tank (FYI which most goldfish tanks are). That’s why it’s a good idea to get a commercial air pump since they can deliver more oxygen to a greater depth, and they are less likely to fail over time.

Deep Substrate

Gravel or a clay-based planted tank substrate is usually the best choice for goldfish. However, you want to avoid sand since it can be unsafe for goldfish and can be hard to maintain.

TIP: In order for goldfish to thrive in their tank a deep clay-based substrate is necessary as it helps remove nitrates from the water when placed on top of an undergravel filter.

Rocks (Real or Artificial)

Goldfish like a tank that has real or artificial rocks. Real rocks provide hiding places for the fish and also help to anchor plants in the tank. Artificial rocks, on the other hand, are beneficial because they do not affect the pH of the water and they are less likely to cause problems in the long run.

Either real or artificial rocks will work, but it’s important to make sure that the rocks are stable and won’t tip over and break your tank or harm your fish. Additionally, you should make sure that rocks with holes in them are big enough so that your fish can fit through any openings without getting stuck.

Goldfish are messy eaters and they produce a lot of waste, so owners must be vigilant about keeping their fish tank clean.

That’s why a goldfish tank should have a deep substrate (at least 3-inches) placed on top of an undergravel filter to control nitrates. Plus, a goldfish tank will also need a powerful canister filter to remove any free-floating debris.

And don’t forget about water changes. Doing them regularly will clear out any built-up nitrates and organic waste. And the more often the better but once every two weeks should suffice if you don’t overfeed your goldfish.

Goldfish Aquarium Chiller or Fan

Did you know that goldfish like their tanks in the low 60-degree F range? While this may seem cold, it’s actually just right for them. In the summer it can be hard to keep your goldfish tank cool enough in some places. That’s why we recommend looking into getting an aquarium fan or chiller if your goldfish tank reaches over 80+ degrees regularly.

Goldfish Tank Heater

Goldfish need a heater if you want to keep them active when the temperature drops. Even though they are very cold-tolerant they will start to slow down and become lethargic when the water temperature in their tank falls into the mid-’50s. This is natural for them, but it makes them less interesting and it also suppresses their need to eat.

If you want to keep your goldfish active year-round you can add a submersible heater to their tank. This will only be necessary during the coldest part of the winter if your tank is in an unheated room or a basement.
