5 Key Things to Consider When Choosing Your Aquarium Fish

Posted by on Jan 10 2018


If you want to know how to choose what fish to have in your pond, aquarium or fish bowl, then we are here to help! There are some things that you definitely need to keep in mind when choosing the right fish for you, because otherwise it could cause all kinds of problems. Instead, have a read of our quick guide to picking the right fish to know what to consider when starting your fishkeeping journey.


1.      Types of Fish and Their Compatibility

When opting to care for fish, you will need to consider the fact that some aquarium fish can act aggressively towards one another. Some fish that can act aggressively are: Red Belly Piranha, Red Tail Shark, Tiger Barbs, Giant Danio, Convict Cichlid, Tangs, Snakehead, Catfish, pufferfish, and the Red Lionfish. These fish can be territorial, easily bothered, or are vulnerable, so they lash out. Sometimes they just fight and maim, but they can often kill other fish, so be careful.


2.      Breeding

If you would like to breed fish, then this is great but if you don’t, you will need to be selective of the fish you choose. It could be in your best interest to get fish of the same gender or contrasting species to eliminate the possibility of reproduction. Although having little visitors isn’t a major issue, if you’re not prepared, it can cause inconveniences and imbalances within your tank. Plus, you would have to care for these fish, too.


3.      Ecosystems

Not all fish work well together as a fully-functioning ecosystem. Some compliment, help and improve one another, whilst others clash, harm other species’ productivity and of course feed on other fish. If the network within your fish tank or aquarium isn’t well thought-through, your fish may not thrive at all.



4.      Freshwater Versus Salt Water

As I’m sure you’ve heard, some fish are native to certain water sources. If you choose fish that are not meant for the water source that you have, then they will only become ill and/or die. It is in your best interest to know the fish you are buying before you just stick any colourful fish into any type of water. This is very bad for the fish, so consider what kind of water source, specific aquarium equipment, or aquarium you want to suit the type of aquarium inhabitants you intend to keep before you buy.


5.      Feeding

Some fish do actually feed on one another! It wouldn’t make much sense to invest in a beautiful aquarium of fish, only for a few to eat all the rest! Make sure you research your desired fish to see if they get along with one another, and if they are likely to feed on the smaller fish.


So, this is what you need to think about when you are purchasing your aquarium fish. It is worthwhile to ensure that your fish will be healthy, happy and thriving whilst in your care. Not taking the above-mentioned considerations into account will only result in wasted money, poor aquarium use, and fish loss. It’s really simple, so take care with your choice of aquarium fish. Of course, when you shop for your fish, be sure to ask a professional’s advice before purchasing. Keep CD Aquatics in mind for everything you will then need, from pond equipment to aquarium supplies.
