Top 4 Exciting Facts About Clownfish Eggs In Aquarium

Clownfish are one of the most popular saltwater fish for beginner aquarists to keep as pets because they are relatively easy to care for. They come in many colours, including orange, yellow, black, blue-green, and white. These clownfish live happily together with corals, sponges, and other invertebrates that help them feel at home in their natural habitat!

But did you know that clownfish can lay eggs? Yes! These eggs float up to the surface of your clownfish tank and hatch into baby clownfish. This blog post will discuss clownfish eggs in aquarium, how to make these eggs and what they require for hatching.

How Many Clownfish Eggs In Aquarium?

In a single clutch or spawning episode, a clownfish can lay anywhere from 100 to 1,500 eggs. A typical pair produce around 400-500 eggs. Would you please notice that this is an Amazon affiliate link? The book is presently out of print, but you are welcome to look it up on Amazon (or see if you can get it in a local fish store). Please note that if you purchase something from Amazon due to following this link, I will get a tiny fee. (There’s no need to feel rushed.)

The quantity of eggs laid by a clownfish at any one moment is determined by:

  • Species
  • Relative age and health of the pair
  • Nutrition/feeding

Larger species, such as the maroon clownfish, have been known to deposit 1,000 or more eggs at once. Smaller species, such as the common clownfish, may only deposit a few hundred eggs.

Even if you can raise all of them, that’s a lot of clownfish babies!

Clownfish clean and place their eggs on a tiny patch of rock near where they spend most of their time. Aquarists who grow clownfish occasionally supply clay pots or tiles as easy-to-remove and convenient alternatives for more natural pebbles in aquariums.

Clownfish spawn every 10-14 days when they are spawning consistently. The eggs of the clownfish hatch after 8 to 10 days. If you try to gather them from a breeding tank, the larvae hatch on consecutive evenings, which will drive you insane.

Feeding Clownfish To Promote Breeding And Laying Eggs

You’ll need a happy, well-fed couple of clownfish if you wish to breed them. So, what kind of food have I been giving my clownfish? I feed them twice a day on weekdays, and on weekends, I provide them three times a day. Live blackworms, brine shrimp (when available at my local fish store), frozen Mysis shrimp, freeze-dried Mysis shrimp, Ocean Nutrition pellets, and spirulina-20 flakes are among my favourite things to feed them.

I binge-feed the black worms when I have them because they are fresh, live food. I cycle among the various meals dependent on how much time I want to spend feeding and what they’ve been eating. (They go wrong in the fridge after a couple of days, so I give them as much as they’ll eat them.) I try not to let things continue for too long when the menu is the same.

An essential thing, in my opinion, is to feed frequently and with enough calories. You want your clownfish to develop fast, gain weight, and have enough calories to reproduce successfully. They won’t be tempted to consume the eggs that way. So, depending on your schedule, serve a range of high-quality, high-calorie items 2-4 times each day.

How Old Do Clownfish Have To Be To Breed And Lay Eggs?

Clownfish can achieve sexual maturity between the ages of 1.5 and 2 years. Because a few external circumstances will impact this, I say “have the potential.”

Clownfish are hermaphrodites, meaning they have both male and female reproductive organs. They are immature guys at the start of their existence. Except for two, all of the fish in the group will remain, immature males, if they stay together. One of the fish will grow into a breeding male, while the other will change gender and become a breeding female.

If she dies, the breeding male reverts to the female gender. The mature, reproducing male is then ‘promoted’ to one of the juvenile males. As a result, I stated that they have the ability to mature between 1.5 and 2 years of age.

However, depending on the dynamics of the group, they may be considerably older and still immature, as seen in the example above. The good news is that hermaphrodism makes establishing a clownfish breeding pair quite simple.

Collecting Clownfish Eggs

If you have your own breeding system, the ideal approach is number 1, which involves removing the eggs before they hatch. If number one isn’t possible for any reason, number two could suffice.

Here are your alternatives if you want to let your clownfish reproduce in the aquarium (or if they already have).

  • You might be able to get rid of the eggs before they hatch. They’ll occasionally lie on a rock or something else that may be removed from the tank. You’re in luck in this situation! To hatch the eggs, simply remove them from the tank. Otherwise, you may try putting something in the spot where they lay the eggs in the hopes that the next time they lay an egg, it will be on the pot, tile, or rock you placed there. This is best done with little 4×4 or 6×6 inch tiles.
  • You may leave the eggs in the tank to hatch. The main disadvantage is that collecting the larvae once they’ve hatched is exceedingly tough. You must be present when they arrive, and you must switch off all pumps so that they are not killed by powerheads or drawn into the filtering system. There are a few possibilities from here.


Will clownfish eggs survive?

Clownfish Eggs: Will They Survive? Yes! Clownfish eggs will live until they hatch, around eight days after fertilization, if adequately fertilized and cared for by the male.

How many eggs can a clownfish have?

She’ll lay 100 to 1,000 eggs, each measuring 3 to 4 millimetres in length. After passing over the nest, the male discharges sperm to fertilize the eggs.

Do female clownfish eat their eggs?

Because most of the eggs will not be fertilized correctly, they will begin to rot, which is why they must be eaten.
