Best fish tanks

If you’re in a hurry and eager to find out the best fish tank. Then we would recommend the Glass Tetra 20 Gallon Complete Aquarium Kit  

In the United States, freshwater fish are the most popular pets to own.  Why? Well, fishkeeping is an inclusive hobby that the whole family can get involved with. Naturally, one of the top items on your list, when starting, will be what fish tank to buy. This article will aim to educate you on things to consider, while also highlighting (what we believe to be) the best fish tanks available in today’s market.

What tank size do I need?

Choosing the correct size tank will depend on the sort of fish you plan to keep. Generally speaking, the bigger, the better. A larger tank (50 gallons plus) should require less maintenance, whether that’s less frequent water changes or cleaning. The filter works to clear the tank of all the waste. So the higher the water ratio to fish will mean fewer toxins harming them. 

Mid-sized tanks are something I have owned before and can be classified as (20-45 gallons). I wanted a mid-sized tank to add real character to a room i.e that ornamental key feature.

Let’s not discard the small tanks, tell me more? The positives of having a small (15 gallons or less) or nano tank (2.5 gallons) are that they’re affordable, therefore, accessible to everyone. From a student bedroom to a crowded classroom, you will always be able to find the space somewhere. Yet, Small tanks can be temperamental. With slight changes in PH levels or ammonia having a significant impact on the tank environment.

What shape do I need?

Fish tanks are available in a host of different shapes. Choosing the correct one has a lot to do with the type of fish you plan to keep. Active fish will thrive in a longer tank, meaning a rectangular design will suit them more. Less active fish would fare better in a tall narrow tank, whereas a territorial fish wouldn’t because they need far more bottom space. Choosing the correct shape is more than just a matter of taste. Having a full understanding of the fish you plan to keep, and their unique behavior is imperative and will ultimately influence your final buying decision. 

Acrylic or Glass aquarium?

Both are clear, and both hold water. When choosing whether to go with a glass or acrylic aquarium, each has its advantages, so it comes down to which one fits your specific needs.

Glass Advantages

  • Scratch-resistant – Glass is hard to scratch, so unless you’re going out of your way to scratch the tank, the chances are that the tank will remain in good condition for years to come.
  • A better price – Due to the manufacturing simplicity, glass aquariums tend to be cheaper than their acrylic counterparts.
  • Stay’s clear – The transparency of glass will not be altered by the chemicals in the water over time. 
  • Hardness – Glass will only become flexible when exposed to extreme heat. Meaning glass can hold more volumes of water without bending.

Glass Disadvantages

  • Poor resistance with impact
  • Limited choice of shape
  • Much heavier than acrylic 
  • Fast heat dispersion meaning it will need to be heated more often

Acrylic Advantages

  • Easy to move – Due to acrylic’s lightweight properties, this makes it far easier to move. 
  • Variety – Since acrylic is born from a plastic sheet, this makes a variety of shapes far easier to mold than glass.
  • Heat retention – Acrylic has far greater heat retaining properties than glass. 
  • Strength – This may seem strange, but acrylic is stronger than glass. A thin sheet of acrylic can be used to hold the same volume of water than the equivalent for glass, which would require it to be much thicker. 
  • Alterability – Acrylic can be drilled into if extra tubes are needed for specific add ons.

Acrylic Disadvantages

  • Will need full stand support from the bottom 
  • Scratches easily 
  • Colour may alter with time

What is a fish tank kit?

In short, when you buy your tank it will most likely include a few extra gadgets. For those starting out and wanting to take the stress away from needing to piece everything together yourself, an aquarium kit is an excellent place to start. They come in a range of different sizes, usually with lights and a filter.
