Switching to a 55 Gallon fish tank

Enjoying fish species in the office or at home became something really easy to accomplish nowadays. When buying the best 55-gallon aquarium which is becoming the standard size, means you’re getting a tank that is big enough to hold smaller fish in large schools but also African Cichlids for instance, yet it does not appear huge.

The 55 gallon aquarium is a great option and it is large enough to shelter big fish, like Discus or Oscars.

There is a need to consider a few things before diving into buying an aquarium this size, how to place it and where, the budget for the said aquarium dimensions, decorations, and so on. Here, you can find listed specific information from our real experiences and this should help you make easier decisions.

Fish tanks are a valuable investment for any enthusiast. It reflects your interest and fascination. There is a need for a robust stand to hold the aquarium model safe. Make the final decision after considering several vital elements. When purchasing any aquarium regardless of its size, we need to pay attention to every detail.

Is a 50 – 55 gallon tank large enough?

There is often confusion among buyers when looking for a 50 – 55 gallon fish tank. It can be rather difficult to imagine how large is a 55 gallon aquarium. The size difference is trivial.

The 50 gallon tank is typically 36 x 18 x 19 inches appearing rather long, while the 55 gallon tank dimensions are 48 x 13 x 20 inches.

Depending on the fish species which are about to inhabit the tank, one of the 50 or the 55 aquariums might be more suitable.

What are the differences between acrylic and glass aquariums?

Typically, acrylic fish tanks are more expensive compared to their glass counterparts, and are lighter. The acrylic fish tank comes in various shapes, while a glass fish tank has a very few classical styles.

Acrylic tanks lose their shine faster in time due to the cleaning processes. However, acrylic is the right option for any home with little children as it is way more difficult to crack.

A glass fish tank is extremely difficult to scratch and looks stunning. It looks new for ages and is less expensive. But is heavier. While buying one ensure to have an adequate stand that handles the weight of the full aquarium including decorations.

What fish can be kept in a 55 gallon tank?

This is a huge tank for most enthusiasts, but how long is a 55-gallon tank should be known to ideally fit large species. Therefore, ideal species to be considered:

Freshwater fish species may include Oscars, Discus and other large Cichlids, Gouramis etc.

Saltwater fish species may include Clownfish, Mandarin Fish, Blue Tangs, Damselfish, Butterflyfish, Coral Beauties, and Blennies. You can include Ghost Shrimp and Nerite snails.

Things to consider while buying a 55 gallon aquarium

Below, several crucial things to consider:

The tank size means the aquarium dimensions, including edges if there are any, and the furniture / stand should be precisely determined. Knowing how large, wide and tall is a 55 gallon tank is a must.

The tank material is a choice determined by the stand setup planned for your tank. For full glass aquarium kits which are definitely heavier, a corresponding strong support/stand should be chosen. Regular furniture stands should be more suitable for acrylic tanks.

Aquarium stand types come in metal, wood, or combinations of both. The metal ones are somewhat cheaper. Whatever the stand material, make sure it resists corrosion and ideally has a cabinet to hide the canister filter and other tools.

The wooden stands are ideal for acrylic tank models. They feature a cabinet or drawer to store filters and accessories. However, we should always bear in mind that buying a stand is a worthy investment next to the aquarium itself.

The design style and location should be considered taking the fish’s weight added to the full tank weight including accessories. One should ensure as well how long is a 55 gallon tank, besides its model and weight.

The location to place the tank should also facilitate support for a beam or LED lighting.

Having a 55 gallon aquarium with a stand comes with plenty of benefits. It becomes a central point in the room having a calming effect offering a balance of mental and physical health.

It does not take a lot of space, it is easy to clean and maintain. Such a tank can be easily personalized with dedicated lighting solutions, plants, and decorations.
