Fish Care

This page outlines some of the common breeding characteristics of the major fish families.  For specific information, use the Fish Facts tab above.

Cichlids often breed on large flat surfaces, such as rocks or the inside of flower pots.  The tank should have no plants and the tank should have gravel on the bottom. Mouthbrooders will dig out the gravel and the female will deposit eggs in the depression. The eggs are fertilized and then taken in the mouth until they hatch.  Angelfish will deposit eggs against plants, such as amazon swords.

Characin and Barbs breed in thickly planted tanks with no gravel, rocks or flower pots.  The best plants are cabomba, hornwort, java moss.  Plastic plants work well too.  The plants generally fall to the bottom of the tank.  Use a flashlight to search for eggs by the reflection.  Parents should be removed after breeding.  For American Characin the water should be soft, acidic and free of bacteria.  The lighting should be very dim for breeding and for hatching the eggs.  Separate the pair before breeding and feed them well.  Spawning will occur in the morning.  Return the pair to the main tank if no breeding occurs within 3 days.  The fry can be raising in a breeding net if space is in short supply.

Anabantids require very clean water.  The male builds a bubblenest by blowing bubbles that remain at the surface.  The pair breeds by wrapping and intertwining.  The eggs of Gouramis tend to float, while betta eggs will sink.  The male should remain in the breeding tank after breeding, as they will ensure that eggs are placed within the bubbles and they will remove infertile eggs.

Livebearers breed continuously, often monthly.  Females will show a bulging stomach and a dark gravid spot near the anal fin.  Females will not eat their newborn, but others will.  Floating plants, such as Crystalwort, will give the young places to hide.  Breeding traps work very well in ensuring that the young survive.
