Top 5 Freshwater Fish Species for Planted Tanks

Creating a beautiful aquarium is not an easy task. There are many aspects and factors you’ll have to pay attention to if you want to create a thriving habitat in your home. Naturally, the choice of the tank and the environment in it can’t be separated from your choice for the fish and critters in the tank. You wouldn’t want your fauna to turn on your flora, right? After you have set up your planted tank and done the work to get your plants started, you next have to think about what kind of fish you want to keep in your tank.

Do not make the mistake of rushing into this decision too quickly – if you make the wrong choice you could end up having all of your hard work ruined overnight. While many aquarium fish will nibble on plants occasionally, many species have no interest in live plants which makes them a great choice for the planted tank. The key is to choose both the fish that won’t have any appetite for your precious aquarium plants, get along with each other, and that will suit your personal preferences in terms of appearance and behavior.

Best Fish for Planted Tanks

There are thousands of different species of aquarium fish out there, but not all of them are a good choice for plants tanks. Some common and popular species – like silver dollars, monos, and rainbowfish – are notorious plant-eaters. If you happen to get one of these plant-devouring fish, it wouldn’t take long for them to decimate your planted tank, so be extra careful with the choice you make. Otherwise, you could lose your tank’s flora literally in a matter of days. So if you’re unsure what type of fish to choose, take a look at our list- below you will find a list of the top 5 freshwater fish species that will not destroy your planted tank:

  • LivebearersMost livebearers including guppies, mollies, platies, and swordtails make excellent additions to the planted tank. Not only are these fish unlikely to eat live plants, but they are usually very hardy and adaptable, which means that you can cater the conditions in your tank to suit your plants and your fish will adapt. Their versatility is one of the reasons for their popularity- they are easy to take care of and come in all types of colors and looks. Of course, make sure that you’re getting the right ratio of males to females and choosing compatible breeds of livebearers to avoid aggression issues in the tank.

  • TetrasThe perfect species for aquarium newbies and experienced aquarists alike, tetras come in many different varieties to choose from. There is a big selection of different tetra species to choose from but most species are peaceful by nature and remain fairly small in size. They are also easy to care for and won’t need much fussing over to thrive in your planted tank. Neon tetra, cardinal tetra, bleeding heart tetra are some of the most frequent choices. Tetras typically do best when kept in groups with six or more of their own species and they are a good choice for the community tank.
  • CorydorasCory catfish are a type of bottom-dwelling fish that subsist on a variety of foods including live food, frozen food, and flake foods. These fish do not tend to eat live aquarium plants (though they will use them for breeding). They are much loved by aquarists for their peaceful nature and lovely looks- the variety of corydoras is not always common for bottom-dwellers. For instance, bandit cory, panda cory, and skunk cory all boast black stripes in different shapes and locations, three-spot cories boasts maze-like spots and the bronze cory stuns with its metallic hues in any of its color morphs. 

Of course, despite the lovely selection of fish that won’t eat aquarium plants, sometimes you have your heart set on a particular species that has a penchant for nibbling on greens. Hey, the heart wants what the heart wants! If you do decide to keep herbivorous fish in your planted tank, just be sure to feed them properly so they aren’t tempted to eat your plants. Herbivorous fish should be fed herbivore flakes or pellets along with dried algae and fresh vegetables. It’s also important to keep in mind that while some fish species don’t eat aquarium plants, they can still be harmful in the planted tank. Cichlids are a good example of this – they don’t eat plants but they do have a tendency to dig around in the substrate which can damage delicate plant roots. 

Cultivating a thriving planted tank is no easy task. Heck, it’s not always easy making sure that just plants or just fish in your tank thrive, let alone both and in a harmonious way, at that! It takes a great deal of work to set up the tank and the tank equipment properly and then to get your plants to grow. Once you’ve done all that work you don’t want to choose the wrong fish and end up having them eat all of your plants. To avoid this tragedy, stock your planted tank with some of  our picks for freshwater fish species.
