How to Take Care of Your Pregnant Neon Tetra
If you’re looking to learn more about your pregnant neon tetra, the first thing you should know is that technically, neon tetras can’t get pregnant as they’re egg layers.
The term “pregnant” is usually reserved for when the young develop within the mother’s uterus, as in humans, dogs, and cats. For the sake of this article though, I’ll use the term “pregnant”, even though it’s not totally accurate.
Now that we have that out of the way, if your neon tetra has a swollen belly, it may mean that it’s a female with eggs. Here’s how you can help her successfully bring new fish into the world, as well as how to successfully breed more neon tetras.
Neon Tetra Courting Behavior
You can tell that eggs may be in your future if you see your neon tetras courting. When courting, the male will display a variety of behaviors as he tries to encourage his mate to lay her eggs for fertilization. The male’s courting behaviors include:
- Chasing the female.
- Nudging his mate’s abdomen.
- Swimming side to side rapidly while displaying his fins and colors.
How Can You Tell If a Neon Tetra is Pregnant?
If the female accepts the male’s advances, she’ll begin to show pregnant neon tetra symptoms. These signs include her becoming more vibrant in color and becoming plumper.
This behavior by the female will cause the male to become more persistent in his courtship behavior as he attempts to stimulate her to lay eggs.
When the female is responsive to the male, she’ll lay eggs, which are covered with a sticky gel that binds to plants or other surfaces in the
How Long Is a Neon Tetra’s Pregnancy?
After carrying her eggs for 14 weeks, the female will lay between 60-120 eggs. The eggs will hatch within 24-36 hours.
Common Issues with Pregnant Neon Tetras
There are a variety of diseases that can result from providing improper care, so it’s important to know what to look out for in case of an outbreak in the tank.
Neon Tetra Disease
Neon tetra disease, also known as Pleistophora hyphessobryconis, is caused by a parasite that lays its eggs on the fish, and its spores enter the fish’s body. When the eggs hatch, the offspring create cysts, which appear on the fish’s body. The cysts cause the body to have a lumpy appearance. Other symptoms include:
- Difficulty swimming.
- The curvature of the spine.
- Discoloration of the body.
- Weight loss.
This disease originates from parasites being introduced to the aquarium by fish that haven’t been quarantined or by feeding live food.
You can prevent this disease by raising your own live food and quarantining all new additions to the aquarium. As there’s no treatment for this disease, prevention is everything.
False Neon Tetra Disease
The symptoms of this disease are identical to neon tetra disease. The only difference is that this disease is caused by bacteria instead of parasites.
Ich
Ich is a common disease among aquarium fish that is caused by the parasitic protozoan Ichthyophthirius multifiliis. This disease presents small white spots on the fish’s body and fins. Fish inflicted with this disease can be seen rubbing against surfaces to relieve themselves of the irritation.
Medication for ich can be purchased at your local tropical fish store. As a home remedy, add one tablespoon of salt for every five gallons of aquarium water and increase the water temperature by two degrees.

Tail and Fin Rot
This disease results from poor water quality and manifests as the fish’s fins being eaten away. With time, the disease progresses toward the body. Treatment includes doing a complete water change and dosing the water with antibiotics.

Dropsy
Dropsy isn’t a disease but rather a symptom of underlying disorders. The fish may have a bacterial infection or a disorder of their kidney or liver.
As a result of the disorder, the ability of the fish to regulate its fluid balance is disrupted. Fluid collects in the fish’s body, and it can’t excrete the excess fluids. Symptoms of dropsy include:
- Bloating or distention of the abdomen, which may be confused with pregnancy.
- The fish’s body resembling a pinecone due to the distended scales.
- The fish’s eyes protruding from their orbits.
- Loss of appetite.
- Lethargy or lying down on its side.
- Swimming in a swaying motion below the water’s surface.
Poor water conditions or an incorrect diet cause this disease. Treatment includes quarantining and adding salt to the water and antibiotics. Add one teaspoon of salt per gallon of water. Also, the water needs to be kept scrupulously clean.
For antibiotics, use one that’s broad spectrum, gram-positive, and negative resistant, such as Maracyn-two.

Caring for Pregnant Neon Tetra Fish
Caring for a pregnant neon tetra needs to start before your neon tetra becomes pregnant. If you plan on breeding neon tetras, you will want to set up a breeding tank, which will be described in the next section.
The breeding tank should have the following water parameters:
- Temperature: 77 degrees Fahrenheit (25 Centigrade).
- pH: 5.5-6.0.
Also, dim the lights in the room or provide plenty of plants in the breeding tank to provide shade. Doing these things will stimulate the female to become pregnant.
