The clownfish is a small, colorful fish that makes a nice addition to any home saltwater aquarium. They are fun to create and can be easily reproduced at home with care, attention and experience. Here are some basic steps that will help you successfully breed clownfish in your own aquarium.
Part 1 of 2: Preparing to Breed a Clownfish Couple
Step 1. Make sure you are familiar with maintaining a saltwater aquarium
Breeding a fish is a project that may need people experienced with saltwater aquarium setup and maintenance. While breeding these fish is not difficult, it does require a bit of knowledge about the fish's diet and life cycle, not to mention the supplies that ensure proper pond filtration and ecosystem development.
If you want to start building your own aquarium, consult articles about it before diving into fish farming
Step 2. Buy a couple at an aquarium store
The clownfish is an external breeder, which means that the female lays eggs and then the male fertilizes them. To do this, you will need an already connected couple, that is, mated.
Many stores sell mated couples specifically for breeding. If the store you go to doesn't have this option in stock, they can place a special order for you. Don't be afraid to ask
Step 3. Develop a couple
The other way you can have a couple is by growing two young clownfish. Start by buying two young clownfish. One of the amazing things about this fish is that they are all born neither male nor female, so you don't have to worry about having a male and a female. Any pair will work.
- Developing a male or female fish will only occur when he is older. Your fish's sex will be determined by dominance when they're fighting. The dominant fish will be the female and the least dominant, the male.
- If you are keeping multiple clownfish in the same tank, you will only develop one mated pair. The most dominant will be the female and the second most dominant will be the male. The rest will remain asexual.
- If you want to keep combat to a minimum and get the fish to change sex as quickly as possible, it's good to have a bigger clownfish, so it's obvious to look for the dominant one.
Step 4. Keep the water in the tank clean
Clownfish are not as sensitive to water conditions as other fish can be, but it will be easier to raise them with clean water.
Step 5. Place plants and rocks in the aquarium
Putting anemones in the tank will make the clownfish feel more comfortable. While this is not completely necessary, it will increase the likelihood that the couple will reproduce. You should also have live rock in your tank as it is an ocean rock and is the basis for the development of coral reefs. The live rock will provide hiding places and a surface that the clownfish can rest on and care for their eggs.
Step 6. Keep the aquarium lighting on a timer
Keep it bright during the day and dark at night on a regular schedule. This regularity will keep the clownfish relaxed and more prone to spawning.
Step 7. Recognize clownfish behavior changes that indicate spawning
The female, the largest of your fish, will get thicker in the middle, indicating that it is ready to release eggs. The two fish can also start cleaning the rocks with their fins and mouth when they are ready to lay eggs.
Step 8. Keep a close eye on the clownfish eggs
When eggs are laid they are orange and stuck to rocks. The male will heal from them by swimming around them and waving his fins to air them out. They also throw away those who die.
Step 9. Track egg changes
They have various stages of development. As stated before, they start out orange but then change.
Eggs should hatch in 7 to 10 days. You will need to feed the rotifer fingerlings for the first week. Rotifers are plankton that feed many species. After that, you can start introducing live saltwater shrimp. Baby clownfish only eat live food
Step 10. Set up a separate hatch tank when eggs are laid
It doesn't have to be very big, a 37, 8 liter tank will suffice. Make sure the tank does not have a large filtration system, but rather an air stone that allows only a few bubbles or other mild forms of oxygenation. Too much filtration could easily kill all your little fish.
You should also provide adequate lighting for babies, as they are looking for food and their eyesight is not very good. The light shouldn't be too strong, just one bulb is enough, and it should be as diffused as possible
Part 2 of 2: Raising the fry
Step 1. Move the chicks to a separate tank
Some breeders move the eggs before they hatch, but most wait until they hatch because it's easier. However, you will need to raise the chicks in a separate aquarium, as clownfish are known to eat their own eggs and chicks.
Step 2. Feed your puppies
While in the egg, embryos use energy and yoke to survive, but when they come out, they need food fast!
- Puppies should be fed live rotifers, which are microscopic aquatic animals. They can be found at specific stores, but you should check with your preferred store.
- Many clownfish breeders find it easier to breed rotifers to feed their young. Make sure you have the necessary supplies before starting the breeding process, otherwise your puppies will die at this stage.
Step 3. Change 20 to 50% of the tank water daily
This is important to keep the water clean, but also to ensure the water is clear enough for the chicks to find the rotifers.
Step 4. Wait for some of the fry not to turn into fish
One of the most difficult transitions in a clownfish's life is when it changes from the larval stage to a juvenile fish.
To give them a good chance of development, switch feeds from rotifers to live shrimp so they have enough energy to grow quickly. You can also add nutrients to the water, such as those sold for health saltwater tanks
Step 5. See how the fry transform into juvenile fish
If the fish makes the complete transition, you should start to see a different color in it. They should continue to grow rapidly, so make sure you continue to provide enough food and keep the water clear and clean.
