The Apistogramma, a genus of Dwarf Cichlids, are only found in South America, in slightly acid waters, where the vegetation is mostly floating plants or plants with floating leaves, and where there are clumps of roots along the banks which provide numerous shaded hiding places. These fish need a carefully arranged aquarium The water should be soft mildly acid, and some Water must be regularly changed. The temperature should be 22�-24� C, although a few species such as A.agassizii and A.cacatuoides can be kept at temperatures as low as 18� C during the winter.Those species which will breed in captivity can usually be bred with little difficulty in tanks with plenty of floating plants: eggs will usually be laid 10 to12 times a year. The eggs will usually be laid in cavities with restricted entrances, for example inverted flower pots, or pieces of coconut shell, but may be laid on the underside of flat stones. The eggs are usually yellow to brownish red, oval, and adhesive.

Killifishes in the Aquarium It is-not unusual for the beginning hobbyist to be attracted to this beautiful group of fishes. They have, from all external appearances, every positive quality that could be desired. Often, however, the novice is warned that killifishes are difficult to maintain and only advanced Aquarius�s can be successful with them. This is not an accurate statement. With limited study and thoughtful preparation, any hobbyist can keep and breed these fish.There are many genera of killifish which are kept by Aquarists Some of these include: Aphyosemion, Cynolebias, Cyprinodon, Nothobranchius, Epiplatys, Aplocheilus, Pterolebias, Rivulus, Roloffia, Fundulus, Pachypanchax, and many more The general maintenance of all these fishes is very similar, while the breeding techniques vary considerably.
