Baby brine shrimp from day one.
A small killifish of Florida and the southeastern USA. Males have blue fins edged in black with orange bases. It tolerates cool water and can live in outdoor tubs and ponds in summer.
David Starr Jordan described the bluefin killifish in 1880 and named it after his colleague George Brown Goode. It is common in Florida's spring-fed rivers, where males flash electric-blue fins among the weeds. North American native-fish keepers prize it as one of the most colourful small fishes of the United States.

FishBase: Lucania goodei summary · Eschmeyer's Catalog of Fishes: genus LucaniaNo Seriously Fish profile exists. FishBase max 6.0 cm TL (source: Huber Killi-Data); USFWS and Aquarium Glaser give about 5 cm; typical wild fish ~2.9 cm TL. Larger well-sourced figure used per size rule; TL. Legacy 5 cm is a fair typical adult size.
FishBase: Lucania goodei summary · US Fish & Wildlife Service (2018): Bluefin Killifish Ecological Risk Screening Summary · Aquarium Glaser (F. Schaefer): Lucania goodeiOnly numeric aquarium range found is FishBase 12-22 °C (Riehl & Baensch). USFWS (citing Nunziata 2010) reports wild fish in water in the high 80s °F and outdoor tubs down to the upper 40s °F, so the species tolerates far more than this; legacy 18-26 °C is plausible for keeping but its upper end is not directly sourced.
