Staurogyne repens is a fresh green, compact and hardy plant for the foreground of the aquarium and it was found in River Rio Cristalino in the southern Amazonas. Its nearest relative in the aquaristic is Hygrophila but Staurogyne is different with its marked compact, low and bushy stature (5-10 cm) and small green leaves (each stem is 3.4 cm wide).
When planting in the aquarium, the longest upright shoots should be cut off and new, horizontally creeping shoots will soon form from the plant basis and gradually colonize the gravel.
At low light, the growth will be more upright and much less side shoots will be formed.
S. repens is an adaptable plant that can be grown in both submerged and emersed environments. Be sure to allow adequate time for the plants to transition. High lighting and Co2 injection is necessary to keep this plant low growing. Vertical growing thin stalks are an indication of lack of lighting while yellowing leaves can mean nutrition deficiency. Thin leaves can also hint at a lack of Co2. This plant can grow quickly and require regular trimming when kept under proper conditions. Trimmings can be replanted as a form of propagation.
