So you want to have a fish tank but don’t know where to start? No worries, we’ve got everything you need. Whether it’s a cold water or freshwater environment, your fish tanks will be complete with our selection of equipment! You’ll find the basics like filters and lights for all types of environments from scratchless saltwater setups too small aquariums in kitchen nooks alike. We’re also proudest about having so many different options that are customizable as well-just ask one of our experts at any time what might work best for your needs!


The water in your fish tank is filthy and you don’t want the smell to get any worse. The last thing that you need to do now, before adding more of these little creatures into their new home, is make sure it’s clean enough for them (and yourself!). That’s where a filter comes in handy! Filters come equipped with 3 different types: mechanical filtration which removes larger particles from waste; biological filtration which converts harmful ammonia and nitrites into less-harmful nitrates; chemical filtration used when organic impurities are too large or numerous for either type of filtering alone. There are many varieties available but most commonly hang on back filters will be best suited for a 15 gallon aquarium like yours.


Fish and plants need light to survive, which is why artificial lighting plays a key role in fish tank maintenance. It replicates natural daylight so that your little friends can grow up healthy – this makes it crucial for successful freshwater aquarium care.

There are many different types of lights available for your tank, from LED strip lighting to incandescent bulbs. The type you choose will depend on the plants and fish you want in it; however, a good all-rounder is LEDs which provide natural light similar to that found outdoors.


Heating your fish tank is a great way to make it more enjoyable for the animals and easier on you. You have many new species of tropical varieties available when heating, with different types of heaters such as fully submersible or in-line that can be customized to suit any situation. The most popular type is the pre-set temperature variety as they are easy options but also allow customization if needed so there’s no need worry about leaving them unattended!

Other Equipment

You will also need some other basic equipment for your tank before you can get started, including: water conditioner to make the water safe and comfortable; a thermometer so that you know how warm or cold it is inside of your fish’s habitat; a bucket in which to place all of the things like gravel syphon, filter media. Algae magnet as well because algae attracts light from aquarium lights making tanks dirty. You’ll also want plenty of food—fish feeders are available on Amazon!

The rest really is up to you, but other popular additions include:

You can’t just build a house in Minecraft, you need to make it look good and function well. Other popular additions include gravel or sand for pathways, rocks as decoration around the outside of your home with caves inside where monsters sleep at night. Driftwood is another way to give your place personality while also making sure that there are enough resources nearby so that people don’t have trouble finding what they need when visiting you (or even better yet if You’re designing their new home). And plants provide both beauty and utility!

Tank Setup Ideas

For those who want a simple setup, consider installing the tank on top of an open shelving unit. This will give you easy access to your fish and plant life while maintaining a tidy appearance at all times. If this is too much work for you, try placing it in front of or below any window that gets plenty of light during daylight hours. The best place for tanks with plants are spaces where they get ample sunlight throughout the day and have room to grow large enough as well!

What Fish Can You Keep In A 15 Gallon Fish Tank?

When you’re setting up your fish tank, it’s important to make sure that all of the creatures are compatible with one another and have similar needs. Here is a list of some colorful schooling fishes:

  • Guppies (active live bearing fish males can be vibrant colors)
  • Tetras (schooling fish which come in a wide variety off colors)
  • Danios(hardy and lively schooling fish)
  • Barbs(lively easy to care for schoolers)
  • Dwarf Corydoras and Platy Fish

Fish are not the only creatures you can keep in a tank. You might also want to try invertebrates that will add color and texture. There is plenty of options, but make sure your fish doesn’t grow any bigger than 2 inches or it won’t be ideal for a 15 gallon setup with peaceful small (1-2 inch) creature friends

Beginners Freshwater Community Tank

If you want to keep things simple we recommend choosing one of the shoaling species above, and keep a group of 4-5 with some shrimps and snails. You can also try these setups below:
1 Dwarf Gourami (male) + 5 Male Guppies + 3 Mystery Snails (+4 Amano Shrimp) or 1 Dalmatian Molly (female). With this set up, you can also add popular freshwater plants such as Hornwort, Anacharis or Java Fern.

Biotope Tank

A popular hobby for aquarists is setting up a miniature biotope tank based on their favorite region or body of water. Those who are new to the journey may have some research ahead before they can accurately reproduce the natural environment, but it’s worth doing plenty of reading and discovering what fish inhabit that area as well as which plants grow there naturally. For instance if you’re looking to recreate a South American river then add in some Harlequin Rasboras!

Breeding Tank

Some people like to keep live plants in their breeding tanks because they provide a warm environment for the fish while most breeders prefer an empty tank with just filters and heaters. Bettas, on the other hand, build nests out of plant leaves so you need to make sure that there is some greenery in your baby’s playpen or else it will be too easy for them get caught up if eggs are laid near any aquatic vegetation.

Most egg laying breeds don’t require much more than a filter and heater but many bettas have difficulty building nests without proper access to watery flora such as aquarium plants

How To Setup Your Fish Tank

Setting up your fish tank may seem like a daunting task, but it can be done easily with the right information. First you need to pick where on earth (or in water) you want your new aquarium home! Make sure that this place is level and away from direct sunlight or any heat sources for best results. Next wipe down the inside of your new home using warm water and an unused cloth so no dust gets into icky waters later! You now have enough room for 2 inches of substrate at base – add some sand if desired before filling half way with tap-water filtered through pebbles/gravels as not to upset fauna who live near bottom floors prime habitat because they will all die off when transferred after being used to dirty

Add the equipment to the aquarium, including your filter, heater and lights. You can then fill up 2/3 of the tank with water before you add plants or decorations as per personal preference. Once everything is in place on top of a layer of gravel for comfort and stability -fill it up to just below where you want it- take out any excess air bubbles by smoothing down one side at a time until all that remains are small pockets from which they will eventually dissipate over several days (this also helps maintain clarity). After this process wait 4-6 weeks so your new fishy friend doesn’t get stressed while their ecosystem cycles again.

If you want to provide your fish with a healthy and long life, then it’s essential that you cycle the tank. There are four important factors in cycling: pH, ammonia levels, nitrites (nitrates) spikes and settling back down again; when they have settled at 0ppm this means your tank should now be ready for live plants or animals!


If you’re someone who’s looking for a good quality and affordable fish tank, then this is the one for you. It can fit in any room of your house – even if it doesn’t have an aquarium stand or table to put it on! The size is perfect as well; you’ll be able to enjoy having some new life with plenty of space left over. This product has been rated 4 out of 5 stars by people who bought it so far.
