Keeping freshwater tropical tetra fish in groups

If you choose to get some tetra tropical fish for your aquarium, it's important to know that they are a very social type of tropical fish. Therefore you should always keep between 8 or more tetra fish together, as they are a schooling fish.

If you don't they will feel vulnerable and threatened and will get highly stressed out. Never, ever get just one or two tetra freshwater tropical fish, as they will become so stressed they will die quickly. A dark substrate will calm them and show off their colors better.

Another trick to help freshwater tropical tetra fish keep calm and happy is to arrange your aquarium decorations so that there are many small hiding spots for them. So remember, keep at least 8 tetra tropical fish together, use darker substrate and give them plenty of hiding spots.

Keeping the right water temperature is vital for tetra fish health and stress also. 73 to 78 degrees Fahrenheit is ideal, and make sure it is kept very clean.

Tips on keeping your tetra freshwater tropical fish

When your planning the layout for your tetra freshwater tropical fish aquarium there are several important things to keep in mind. You should always include an area filled with plants so they can hide and feel safe. Never keep tetra tropical fish in a completely plant free aquarium as they will become stressed.

However you also should make a open area for them to swim in. A 25% to 30% area with plants and the rest open is a good idea. Adding floating plants that dim the light a little will encourage tetra fish to swim around in the open more.

Changing the water frequently and keeping it clean is the best thing you can do for your tetra freshwater tropical fish. Tetra tropical fish can be added with other freshwater tropical fish that are peaceful in nature.

However avoid putting tetra fish in with aggressive tropical fish, as it will stress them out very quickly. Getting tetra freshwater tropical fish for your aquarium adds a lot of color and they are fun to watch. Keep these simple tips in mind and your tetra freshwater tropical fish will be happy while giving you hours of visual enjoyment!

      These are the hardiest fish I have ever had, we've had them for 2 years, only four, and just now has one disappeared. I have the fish with black fins and the orange body! Absolutely amazing fish, we feed them normal flake food. Ours were never stressed in their small group, and we think the cats might have finally harpooned one. Not sure how they managed that, though...

      Sorry to hear about your fish. Yeah they need very clean water high in oxygen. Maybe next time you will do better with them. :)

      Good article. Easy to read.

      I tried several times to keep Cardinals in a Biorb fish tank with plants & 2 water frogs but the fish died. I was told that the tank was too small and maybe the nitrates were killing them. I finally gave up. I need a bigger tank. One day. I am a landscape architect and had fun designing the aquarium with plants and found that the Cardinals look great in with them. I guess they didn't think so.
