Small Aquarium Fish

Small Aquarium fish, especially for the newcomer to pet fish tanks, need to be hardy, nonaggressive, not prone to disease, and a few other factors we will discuss here.

If you are only going to have one fish per small tank, here are the easiest fish to care for. If you have more than one fish, watch for particular species which are aggressive and will harm or even eat your other fish.

When we say to start out small and don’t go exotic until you know what you are doing, we mean to try one fish at first, to see if you even like to clean the tank and feed your fish daily.  See if your tank is a blessing or a chore.  

You might consider starting with a desktop size 1-gallon fish tank (3.7 litre), or 10-gallon fish tanks (37.8 litre) are a great size for smaller rooms.  In my opinion, every bedroom should have one for a soothing night light.

5 Best Freshwater Aquarium Fish For Beginners

Find Safe Surroundings For Small Aquarium Fish

Find the safe plants you can use in your fish tank, as many can be poisonous.

Never use unapproved fish tank ornaments, as toxins can leach from them, poisoning your fish.

Always find the most nutritious food.

Know where your tank will go. It cannot be in direct sunlight, although a little-filtered light is good.

It can’t be next to heating and air conditioning vents or drafty windows and doors, as it can make the water temperature fluctuations too drastic for the fish to survive.

It shouldn’t be in the high-traffic area of the house as startling your fish can send them into shock.  A nice cosy corner of your room is almost always a safe bet.

Protect your fish from other family pets. Cats eat fish! Even the most trusted kitty can turn into the crafty predator that can get into any fish tank in Houdini time.

Don’t allow dogs to jump onto your tank. Even the sturdiest tank stands can’t stop a 50 lb. dog. Your fish can also go into shock of that.

Go as low maintenance as possible with a beginner tank. You can even move it off to a bedroom for soothing nights, and get a bigger one when you are ready. Learn more about Kids Aquariums and Starter Fish Tanks here.
