In the last article we went over how to get your Angelfish to spawn.

This is what hooked me on Tropical Fish as a young boy and I still, 45 years after my first spawn, find it fascinating.   The first sign that your Angelfish are getting ready to spawn will be their obsession with cleaning the slate or breeding cone you provided.  It will always be on a surface that is mostly vertical and if you do not provide a surface that meets that condition on which you want them to use for spawning, they will spawn on other surfaces that are much more difficult such as the side of the tank or filter tubing.  Once you see both of them cleaning the spawning site, spawning will usually follow within a day or two.  You will also see them start doing the mating dance.  They will swim towards each other at a slightly upward angle.  Once they get next to each other, they will shimmer and then swim away from each other at a slightly lowered angle.  The mating dance is not always performed.  I have found that Wild Caught Angelfish almost always do it, but  later generations of tank raised strains often do not.  The most spectacular aspect of the spawning will be the colors of your Angelfish.  Whatever their color, it will become MUCH more intense and vibrant during spawning.  This will be the prettiest you will ever see your Angelfish.  They will also become aggressive toward other fish, including other Angelfish, at this time.   They will aggressively defend the breeding site from all intruders, including you.  If you put your hand in near the spawning site when they are preparing to spawn or have already spawned, they, usually the male, will bite your hand.  While it really does not hurt much, they will do it very aggressively, it will startle you and it will be something you want to avoid.

At some point after your Angelfish start doing all of the above, they will actually lay the eggs.  It will start with the female rubbing her belly, and her breeding tube, against the surface that they have cleaned.  She will always lay in an upwards motion.  The total length of the spawning run will be between ½ and five inches.  She will lay between 1 and 12 eggs per spawning run.  They can lay over a thousand eggs at one spawning, but it it usually 3 to 5 hundred.  The more mature the pair, the larger the spawn will be.  The male Angelfish will usually then follow directly behind her in the same basic motion fertilizing the eggs.  The entire process can take between one and five hours.  The eggs will usually be beige

This is when the fun is over and the frustration can start.  The first two issues that you will be confronted with are eating of the eggs, especially by the male, and infertility.  In the next article in this series, we will go over Angelfish eating the eggs.
