Typical egg scatterer. It may be best to allow pairs to develop from within the shoal. A separate tank is advisable for spawning, so that the adults can be returned to the main tank after spawning, to avoid the eggs being eaten. Can be bred. Temperature 26.5°C, 7 ph, 10dGh.
Breeding: Spawning and raising the fry is a relatively simple task. Set up a breeding tank of at least 20 gallons. Keep the water slightly acidic for breeding. The tank should have a heater, sponge filter, a layer or two of marbles on the tank bottom to hide and protect the eggs, and a few live plants. Lower the temperature to 25 degrees Celsius. Introduce the female first and condition on a variety of live, frozen or freeze dried foods like brine shrimp, the same goes for the male, but keep them separate for two days before introducing the male. When the female has filled with eggs put the male in the breeding tank in the afternoon. You will/should notice them instantly start to swim around each other and the male will “head stand” and spread all his fins right out and display to her, this will excite the female.
The actual spawning will take place the following morning. The male will franticly chase her through plants, nipping at her anal and ventral fins, soon the female will allow him to catch up with her, he will force her against the plants and she will release 1 – 3 eggs, which the male will instantly fertilize. Then the eggs will fall into plants and in between the marbles. Sometimes marbles can be a bad choice as some fry may become stuck in between them. The marbles also mean that you cannot tell whether you have any eggs unless you can see under the tank. Feed the pair white worms or bloodworms to reduce the amount of falling eggs they eat. Females can hold 200-700 eggs and will release them 1-3 eggs at a time. They will keep this up until all her eggs have been released. After she has released all of her eggs the pair will simply loose interest with each other, it is time to remove the pair. Put the male back in the community tank, the female can be added to the community tank or you can put her in a recovery tank for 2 weeks, then add her to the community aquarium.
You can carefully take the marbles out of the breeding tank, checking to make sure there are no eggs attached to them, leave the plants, heater and sponge filter in. Eggs that turn white can be removed as these are infertile and the fungus will spread to fertile eggs killing them! The eggs will hatch in around 48 hours.
Raising the fry: Once the eggs have hatched, you will notice tiny fry stuck to plants and the tank sides. They look like tiny shards of glass with 2 black dots, the eyes.
Do not feed the fry until they are free swimming as the fry are absorbing their egg sacs, this usually takes around 5 days. Use this time to culture infusoria (tiny microscopic organisms that the fry can eat) and baby brine shrimp. As soon as the fry are free swimming they will be looking for food, now is the time to start feeding, they will eat anything that can fit into their tiny mouths, so start with infusoria. You can buy commercial fry food, but not as many fry can find that food, they prefer the food to swim to them. After a further 5 days, you can start to feed them newly hatched brine shrimp nauplii, this will sometimes turn their stomachs orange, it won’t harm them, this is just the colour of the food. When the fry get a little bigger, you can start to feed them finely crushed tropical flakes (which you can make by crushing some flakes to powder). Then when a little older, you can move on to feed them a little older brine shrimp (juvenile) or daphnia, or crushed freeze-dried foods. When the fry reach a size of 11mm, you don’t need to crush up their food as much. Carry that on until they reach 2-2.5cm, then you can feed them regular sized flakes and foods. Fry will need to be fed no more than 3 times a day, when feeding infusoria, a small amount in the morning can last all day!
When the fish reach 2.5-3cm, you may add them to your community tank
