there's some Endler's at an aquarium shop here. and i' very tempted to change my cardinal tetras to these ... my aquarium is 27 litres and i think the cardinals are slightly too large for it in a shoal. i also suspect they eat my cherry shrimps. Anybody had experience with the endler's? they look stunning i must say. very striking colour. but i'm not sure if they shoal, are they easy to keep, do they jump? my tank is uncovered and i dont want dead fish on the floor after 2 days.
