01
Overview
Crenata does what hirsuta does at an even lower altitude, often holding barely a centimeter or two tall. It comes from rice paddies and seasonal shallows, pre-adapted to the ordinary aquarium's mediocre light and stable warmth.
02
Aquascaping use
Its miniature scale suits nano foregrounds and the front seam of low-energy layouts. Individual spade leaflets stay distinct, giving a cobbled rather than turfed texture.
03
Planting
Plant rhizome fragments shallowly and close; the creeping stems weave a firm mat over months. Resist relocating sections once they knit.
Nutrient-bearing substrate
04
Light & CO₂
Low light is adequate and keeps it lowest; the leaves simply track the energy offered. CO₂ merely hurries a plant defined by not hurrying.
05
Substrate & fertilization
Occasional root tabs sustain the creep. It asks nearly nothing of the water column.
Feeding behavior: Root feeder. Nutrient demand: moderate.
06
Growth, trimming & propagation
None in practice; lift and reset any layered edges annually. It is close to zero-maintenance once established.
Runner separation
07
Common problems
- !Very slow coverage tests planning
- !Mixed leaf forms during transition look untidy
- !Easily overshadowed by taller foreground neighbors
