Tetra Breeding Basics


Tetra breeding is really quite simple if you follow a few rules. Tetras are among the most popular choices for community aquariums and breeding these fish are not hard. In general, tetras are peaceful, gentle fish that come in a variety of colors. If this is your first attempt at breeding, you may want to start out with simpler species, like Black Skirt Tetras, Red Eye Tetras and Flame Tetras.

In order to keep the water as sterile as possible, it’s really important to change it frequently, especially after breeding has occurred.

To improve your chances of a successful tetra breeding attempt, prepare a separate breeding tank, and darken it by covering the sides with black paper or cardboard. Keep the males and females separate about two weeks before breeding. This will prevent breeding from happening until you are ready, and it will also enhance their affinity for each other.

One good tip is to place the females in the breeding tank first, ideally, the night before breeding is to take place. This will allow the male to properly court the female on her own turf.

Tetras like to eat their own eggs, so be sure to remove the parents after the breeding is complete. At this time, you can remove the Java moss, a showing of fine leaved plants, or an artificial spawning mop. Since the eggs are sensitive to light, keep the tank in darkness for at least 5 days.

After the eggs are laid, it will take about 24 hours for them to hatch. To become free swimming, it will take another 5 to 6 days. At this time, and not before, you can begin to feed the fry. You may also allow some light into the tank, but don’t put them in full sunlight!

Once the fry are free swimming, and have absorbed their yolk sacs, it’s time to feed them. At first, they will need very tiny bits to eat. The easiest way to feed the fry is to introduce a colony of microscopic organisms that the fry can eat. You can do this easily by introducing Java moss.

After a couple of days, the fry will be able to handle a bit more. Good choices include vinegar eels and baby brine shrimp. Once at this stage, make sure to feed your new tetras several times a day to keep them plump and happy. Over the course of a few weeks, you will finally be able to add a good powdered flake to their intake.

As you can see, tetra breeding is not hard, you just need to carefully follow the steps mentioned above. Once you have a nice crop of tetras, you will be able to offer them for sale.

3 tips for marine aquarium newbies


Many newcomers to the salt water aquarium hobby ask how easy or difficult it will be to keep a marine aquarium for the first time. This is never an easy answer to give because there are so many factors involved in setting up and taking care of a salt water fish tank. On the bright side, there are certainly many tips that can make having a first marine fish tank easy on the newcomer!

Marine Aquarium Tip #1 – Go slow but learn quickly
Taking your time and learning as you go is the most important tip for anyone who is new at keeping marine aquariums. The learning curve is a bit steeper than with freshwater aquariums because many salt water fish and corals thrive within a narrow range of paramaters than their freshwater counterparts. Taking time while learning the ropes can prevent many frustrations and potential disasters from occurring. This is also important, because a new marine aquarium actually takes many weeks or months to setup properly to avoid unnecessary deaths of corals and other reef inhabitants.

Marine Aquarium Tip #2 – Stick with easy, tolerant species
For anyone new to any hobby, it is a good idea to start out with easier tasks. In marine aquariums, this means having a strict limit of well-established hardy fish and corals. Like in tip #1, taking time to properly research and learn about any potential add-ons (whether fish, coral, or clean up crew) will make a reef tank more fun to have. Learn about the requirements of the species, and how tolerant they are to changing conditions. Tolerant, hardy species will better withstand the inevitable fluctuations in salinity, hardness, and pH that will occur in the novice’s marine aquarium.

Marine Aquarium Tip #3 – Go big!
With a marine aquarium, size really does matter. Nano reef tanks are more prone to big fluctuations in water quality as well as all the factors mentioned above. These small salt water fish tanks are only suitable for more advanced hobbyists. For a first tank, a setup larger than 50 gallons should be adequate to help stabilize the vital parameters and make owning a first marine fish tank easier. Plus, you’ll eventually be able to house a more diverse group of salt water corals, fish, and invertebrates as you become more familiar with having a marine aquarium.

Black Neon Tetra Guide


The Black Neon Tetra, also known as Hyphessobrycon herbertaxelrodi, is a native of Peru. This species is distinguished by its adjacent horizontal stripes, always a white stripe above a black stripe. Although they have a similar name as the Black Tetra, they are actually different species!

Rather small, it grows to about 1.5 inches (4 cm). Even though smallish in size and can be kept in a smaller aquarium, the Black Neon Tetra do better in schools of 6 or more fish, so having a larger tank is advisable.

The Black Neon Tetras are great community fish to have, as they ae quite peaceful and get on nicely with other fish. Other small, peaceful fish such as Glowlight Tetras and Corys make good tankmates.

Black Neon Tetras prefer soft, acidic water with an ideal pH of 5.5 to 7.5. They are hardy enough however to adapt to hard, neutral water if necessary. To bring out the maximum coloration, peat filtering is suggested. This advice also holds when breeding.

Ominivores, the Black Neon Tetras will eat a variety of food. A combination of quality flake food, frozen and fresh can be offered. They also do well with brine shrimp and bloodworms. This species is quite undemanding and will eat most things offered to them.

Telling the males from females are quite easy. The males are more long and slender, as opposed to the more rounded nature of the female body. The Black Neon Tetra is fairly easy to breed at home, so it’s good beginner fish if you are just breeding for the first time.

To breed, choose a pair of healthy fish, at least a year old. While younger fish can breed, it’s best to get a mature pair. prime the couple beforehand by feeding them high-quality flake food, along with live brine shrimp and mosquito larvae. This will get them into the breeding mode.

Prepare a separate breeding tank, with dim lighting. If low lighting is not available, place cardboard along the sides of the tank to darken it. Additionally, provide some dense plant cover as well.

When the breeding tank is ready, place the male and female in the tank. You will notice that spawning will take place earlier in the day. The female will then lay her sticky eggs along the plants. Once the eggs have been laid, promptly remove the pair of fish from the breeding tank to prevent them from eating their eggs and fry.

Fry, once hatched, can be fed regular fry food, along with finely crushed flake food and freshly hatched brine shrimp. If you are looking for a good starter, community fish, then the Black Neon Tetra is a fantastic choice.
