It is a shame that most people are scared by the diminutive killi even if they are among the more easily to maintain and multiply fish.
Misleading rumors are an incredibly bad idea that encircles the killifish. It is still a regret because they are easy to maintain and reproduce.
I always treat the water to get rid of chlorine, but only to kill species which are well in hard water and alkaline that comes from my tap (pH 7.8-8.0). These fish are members of the Nothobranchius species and they are originally from Tanzania.
There is also a species with many members known as Amphiosemion. Alot of them are found in tropical forests in Congo and Gabon where water conditions are opposite, and soft acid – similar to our rain water.
No knowledge of chemistry is needed by someone to maintain and multiply can killifish.
Setting the kill most species are divided into two types of water demands, let’s look a little different applications for temperature.
While killifish are found all over the globe they are from Africa and South America. Amphiosemion and Nothobranchius species are bout (usually shortened to notho and amphio) originating in Africa.
Notho originated in the eastern part of this vast continent. Live and breed in ponds that evaporate in the dry season, leaving behind thousands of eggs hatch early in the rainy season. So to mimic these conditions it is best to keep the temperature around 25 ˚ C, a slight variation could improve the eggs deposit.
Amphio on the other hand have a more weirder request. The key of the temperature isfound in the rainforest species that prefer cooler temperatures around 21˚ C. A lot require even lower temperatures to increase.
A member of the association BKA (British Killifish Association) managed to grow one of these species when his water heater “cracked”! Is often the case in which a partial water change may trigger breeding.
Even if I remove 30% of water every 2 weeks and every 7-10 days Amphio to Notho, I do not use sponge filters for biological filtering. Others use them or something like them but I do not see why it would be necessary.
Another advantage of maintenance is that you can grow killifish in small aquariums. A pair or a trio are happy enough in an aquarium with dimensions between 30cmLx20cm x25cm height with regular water changes. But you need a larger aquarium if want to go on the species between 10 to 13 cm.
Using peat as a substrate that has none of the chemicals found in many compositions you can find in substrate. Drying a lot of tannin first drain. Squeezing is a good escape from the more brown water. (Which some buy) In small tanks two or three handfuls of peat is enough.
