Why We Love it:

  • Built-in (hidden) 3-stage filtration system with adjustable flow rate

  • Sliding glass canopy for easy access

  • Curved corners for a seamless face-on design

Summary:

The Marineland LED Portrait is possibly our favorite rimless 5 gallon aquarium on the market. It’s the most space-saving design, due to the upright construction with minimal footprint. It comes with all the basics, from a LED light that has white and moonlight settings to a built-in back panel filtration system to keep your water healthy and reduce maintenance. This kit is ideal for those looking to have fish that need a gentle current (such as a betta) as the flow nozzle can be turned down. Incredible value for the price (other tanks like this often run for double the cost).

Some prefer to upgrade the light fixture to something that supports plant growth.

Difference between Aquarium Kit vs. Regular Tank

An aquarium kit includes other equipment besides just the tank itself.

You’ll often find filtration (whether separate or built in to the tank itself), lighting (standard or suitable for plants), and a lid or hood are the common accessories in a kit.

Sometimes hobbyists will get the kit just for the tank itself, if the price is a good value.

Then you can outfit the tank with whatever separate modifications you would like to make in terms of equipment.

Why?

It helps give you the flexibility you need when you’re striving for that final, fantastic look.

Are Rimless Tanks Worth it?

Rimless tanks may a bit pricier than standard tanks with the famous (or infamous) black trim.

But the aesthetic advantages of a frameless design can be pretty major.

These tanks are specially constructed to function without the use of a frame, which has been typically used to help brace the tank against the weight of the water pressure.

Frames are usually black, but might also be woodgrain.

The problem is if you don’t like it, there’s not much you can do about it.

Physically taking off the trim can endanger your pets as it wasn’t designed to function without that brace and may explode tomorrow or in several months.

Painting it doesn’t seem to go well for most either (the paint tends to chip and can just look tacky).

Starting off with a tank that doesn’t have a rim can spare you of all this headache.

So you have all the focus on what’s inside the tank…

… Rather than what’s around it.

If you want your aquarium to be an attractive accent to the room, going with a rimless design can do wonders for making it a living work of art that everyone compliments.

Whether your home or office is more contemporary or traditional, a tank with no rim goes from a distraction to a masterpiece.

What Fish are Best for a 5 Gallon Tank?

5 gallon fish tanks are considered nano aquariums.

The most popular choice would definitely be betta fish.

But there are many other tropical fish as well.

Snails are always a good tank mate to include to help with algae maintenance.

You can also create combinations of fish (provided they get along well).

Also:

Don’t forget your 25 watt heater which will keep the temperature stable for your 5 gallon rimless aquarium.

The hydor is a popular option:

If you want to keep a larger number of fish, you might consider a larger framless tank.
