Apistogramma are found within many river systems and streams in South America. These fish in general prefer a pH range of 5.6 to 7.0 depending on the species and indicative habitat. Acceptable hardness ranges from 1 Gdh to 20 Gdh depending on the species. Water temperature should be maintained between 75 to 80 degrees. Most of the fish could be considered shy and dither fish are recommended (tetras, pencil fish or guppies) . Tank size from 10 gallons and up are acceptable for pairs. Dominant males will fight aggressively for territory. Most species are polygamous harem spawners. Lots of plants and logs/caves are recommended for shelter and spawning sites for this genus of fish. When you create the caves don't use calciferous rocks this will increase the hardness of the water. Recommended plants: Java Fern, Java moss, Amazon swords and Hygro.
Pteraphylum Scalare are found within many river systems and streams in South America. These fish in general prefer a pH range of 6.5 to 7.0 depending on there indicative habitat. Acceptable hardness ranges from 1 Gdh to 20 Gdh depending on the species. Water temperature should be held between 75 to 85 degrees. Because of much domestic breeding the water quality ranges can vary widely. These fish could be considered moderately aggressive. Fish of the same size should be chosen as dithers. Tank size from 20 gallon high tanks and up are acceptable for pairs. Dominant males will fight aggressively for territory. Most species are monogamous pair spawners. Lots of high sprouting plants and sticks are recommended for shelter and spawning sites for this genus of fish. When you set up your tank don't use calciferous rocks these rocks will increase the hardness of the tank water. Recommended plants: Java Fern, Amazon swords, Hygro and other high sprouting plants.
