The Neet Cichlid, scientifically named Neetroplus nematopus, is a small and distinct species of cichlid native to Central America, found in rivers and lakes from Honduras to Costa Rica. This fish is sometimes referred to as the Poor Man's Tropheus, due to its dietary habits and behavior which are reminiscent of the African Tropheus species, but it is more accessible in terms of care and cost.

Neetroplus nematopus has a relatively robust and laterally compressed body with a maximum size that is manageable for most aquarium setups. They typically display colors that range from grey to olive green with a variable number of vertical bars on their flanks, which can be more pronounced during breeding or when the fish are displaying aggression. During these times, their colors can intensify, and they may show bright yellow or orange in the throat and belly area, adding to their visual appeal.

In the aquarium, Neet Cichlids thrive in environments that replicate their natural habitat, which includes plenty of rocks and caves for establishing territories. Given their territorial nature, it's important to structure the aquarium in a way that provides multiple hiding spots and visual barriers. This setup not only accommodates their natural behavior but also helps in reducing stress and aggression among tank mates.

The water conditions for Neetroplus nematopus should be kept clean and stable, with regular maintenance including water changes and efficient filtration to manage waste and maintain water quality. While they are generally adaptable, slight to moderate water hardness and a neutral pH are ideal to keep these cichlids healthy.

Diet-wise, Neet Cichlids are primarily herbivorous, requiring a diet rich in vegetable matter. In the wild, they graze on algae and biofilms, and in the aquarium, they should be fed high-quality vegetable-based foods such as spirulina flakes and pellets. Supplemental foods can include blanched vegetables like zucchini, spinach, and peas. It’s important to restrict their intake of high-protein foods to avoid digestive issues.

Breeding Neetroplus nematopus can be quite straightforward once optimal conditions are met. They are substrate spawners, typically laying eggs on flat surfaces such as rocks or wood. The male often guards the spawning site while the female cares for the eggs and fry. Breeding behavior includes cleaning the chosen site, vigorous shaking displays, and the female fanning the eggs to keep them oxygenated.

Conservation concerns for Neetroplus nematopus include habitat loss and pollution in their native environments. As with all wild-caught species, sustainable practices in the aquarium trade are crucial to ensure that natural populations are not adversely affected.

Overall, the Neet Cichlid offers a fascinating glimpse into the complex behaviors of cichlids in a more manageable size and temperament. Their care requirements and striking behavior make them suitable for aquarists with some experience in keeping cichlids who are looking for a rewarding challenge.
