Pacific Tomato Clown have laid eggs!

This evening I noticed some little red bubbles next to my anemone, would you believe my clown fish pair have laid eggs for the first time. I have had them for over 3 years, they were bought separately and slowly grew into a pair, they now share the anemone.

This is the first time I had ever seen clown fish eggs, I was going to remove them from the rock and place them in a hatchery box but after some research they suggested to leave the eggs with the parents. The male actually cleans the eggs.

Unfortunately overnight the eggs have disappeared, I read that first time parents may sometimes get confused and eat their eggs, hopefully next time will be more successful.

I now know they are capable of mating so lets see what next week will hold.

Pacific Tomato Clownfish Mating Pair

Breeding Clownfish Article:

Breeding clowns is a very rewarding experience, and it's not nearly as hard as you might think.

Obviously the first thing you need is a mated pair. There are several options to getting these. First learn to sex them... which is quite an interesting pursuit when it comes to clownfish.

In a group the female is the largest, with the male as the second largest. All others will be juveniles and gender-neutral. When one of the adults disappears, the next biggest will take its place. Thus the male will become female and a juvenile will turn into a male. Once they are female they cannot change again. In certain species there are physical differences but it's not a real good idea to rely on this as they may have changed sexes but not markings.

Buying an established pair is perhaps the easiest way to go. Many aquarium/fish stores have these or can order them for you. Sometimes you get lucky and get a pair already spawning. Look for a pair that hangs out together as this is a good sign that they are a true pair.

Another possibility is buying a group of juveniles and raising them to breeding age. This takes a good deal longer as some species take quite a while to mature. Also certain species are more aggresive and you may have to remove unwanted extras. Basically, you watch as the group matures and they will pair up by themselves. The female will be the largest, with the male next biggest. The rest should stay juveniles. Establishing an adult pair can be a little tricky, and a close eye needs to be kept on them to make sure that the female doesn't kill the male. Buying a large adult and getting two smaller ones from a group and letting the female pick one is an approach that has yielded a good deal of success. With maroons, try introducing just one male at a time and keep a close eye on them. It takes patience to get them to spawn, and there are a few things you can do to help.
  • Use a good quality live food in combination with a well rounded diet. Fresh shrimp frozen and then grated is a good nutritional source.
  • Make them feel secure. Remove any aggressive fish that might make them feel threatened.
  • Sometimes a good porno movie helps.
  • Have more patience

The Set-up

  • The larger species will need a 29-gallon and the smaller a 20-gallon tank.
  • Some type of filtration that will not harm the larvae when they hatch.
  • A clay pot or a piece of ceramic tile is a favorite to spawn on.
  • A heater.
  • A light on a timer -- regular day/night cycle is important.

Feeding the Larvae

This takes some preparation and is really beyond the scope of this page. I recommend reading the Plankton Culture Manual from Florida Aqua Farms. Its tells all you need to know and more about raising nannochloropsis oculata, greenwater, and Brachionus sp., rotifers. They also can provide live cultures and starter kits. Rotifers are the first foods and must be fed immediately to the larvae. Depending on the species you'll need to feed them rotifers for the first 3 days to 3 weeks.

The Day of Hatching

When the eggs are first laid they are a bright orange. After a couple of days the color fades and eyes appear. The male guards the nest and fans the eggs to keep them oxygenated. Depending on the temperature, around day 8 the eyes will become silver. This means its time to hatch.

At this point you must decide to stay up after the lights go out and catch the larvae or move the eggs to the larvae tank. If you decide to leave them with the parents to hatch you can shine a flashlight in the corner of the tank. The larvae are attracted to the light and then you can either syphon the larvae out or scoop them out with a ladle. If you move them you must keep the eggs aerated gently with a airstone or fungus will set in.

The Larvae Tank

A simple 5 or 10 gallon tank works fine for a larvae tank. Add a heater and an airstone and you're set. No real biological filtration is usually provided. I have used live rock, but there's always a chance of bacteria infection coming from it. Ammonia needs to be monitored. Adding Amquel or its equivalent when traces show up have been beneficial. Having a bare bottom makes it easier to clean. You may need to leave a light on the first few until the larvae develop their hunting skills.

The first 10 days are the most crucial. This is the period when the greatest number are lost. For some reason metamorphosis (around day 10) is very stressful. Immediately following this transition stage, the youngsters will begin developing their stripes... after which point you're pretty much home free. And free to enjoy your beautiful little clowns!

Good luck!
