Splash Tetras lay their eggs OUT of the water — on overhanging leaves. The male then splashes water onto the eggs every few minutes until they hatch and drop into the water.
Species origin data is compiled from peer-reviewed scientific literature, FishBase (the global fish species database), and verified collection records. Geographic coordinates represent the core native range for each species — many have been introduced to other regions but are mapped to their original habitat. Care requirements are based on established aquarium literature and experienced keeper consensus. This database is actively maintained and expanded. Have a correction or suggestion? Contact us.
