Head and Tail Light Tetra (Holopristis ocellifer)

Remarks: Head and tail light tetras are a great choice for beginners and small tanks. They have bright yellow bodies with two iridescent spots on the tail and behind the gills. They should be kept in groups of at least 6.   The scientific name for the head and tail light tetra used to be Hemigrammus ocellifer. However, it was reclassified as Holopristis ocellifer after the completion of an intensive phylogenic study on species in the family Characidae. Many other species were reclassified as well as a result of this study which can be read here: https://academic.oup.com/zoolinnean/article-abstract/202/1/zlae101/7748269   The following article also provides a good breakdown of the results of the study and does not have a paywall: https://aquainfo.org/the-end-of-the-characidae-family-as-we-know-it/ Scientific Name: Holopristis ocellifer Common Name: Head and Tail Light Tetra Max Size: 1.5" pH: 5.0-8.0 Hardness: Soft Temperature: 70-82° Aggressiveness: Peaceful Region of Origin: South America Captive Bred or Wild: Captive Bred Diet: Small flake or pellet, small frozen or live foods
