Looking on the biotopes of Neotoca bilineata, they suggest the species may prefer a habitat with none to moderate current, structured with gravel, rocks, roots, branches, fallen leaves and a lot of submerse or/and river bank vegetation. Fry is usually not eaten, but it may depend on the quantity and quality of food and on the number of places to hide. When the circumstances for this species are good, it is easy to get a flock breeding colony.
  The recommended tank size is at least 60 liters, bigger tanks are not really necessary, but the tank should not be too high (15 to 20cm are enough). With some rocks or roots and dense vegetation well structured tanks combined with dead leaves seem to do best with this species. The current should be none to moderate. However, this species seems to be the only one accepting a lower oxygene level (at least 6mg/l). 
  In the wild, the species feeds mainly from small invertebrates like Copepods or insect larvae, aufwuchs and detritus, so feeding with similar food like water fleas and other food from animalistic sources will be best for this fish. In aquarium, it feeds also from frozen or freeze dried food and even tablets, flake food or granulate. Additionally given Nauplia of Brine Shrimps are eaten greedy and might be an essential part of feeding. The species doesn't act shy. 
  Concerning water quality, this species is not in need of bigger water changes (20-30% every second week are enough). Nevertheless, keep an eye on the water quality. Otherwise, in combination with constant temperatures higher than 24°C, fish may get sick, lose resistance against diseases and age too fast. So for keeping the strain healthy and strong, give the fish a rest during winter time with temperatures lower than 20°C for 2 or 3 months so they stop producing fry. In spring, when the temperature slowly increases, they will start spawning at 17 or 18°C and won't stop until it gets colder again or when it gets too warm (24°C).
  This species is doing very well when is kept in the open from spring to fall, starting when the water temperature by day exceeds 15°C and cold periods are no longer expected. Bring them out in the early afternoon, the time of the day with the highest water temperature. During the warm summer, reproduction will stop and may occur again in fall. Bring the fish in before the water temperature deceeds 15°C by day and keep them cool for the first days, then slowly raise the temperature but try to stay below 20°C over the winter time.
