This species comes from Australia and becomes 5-10 cm tall. There are many species and variants of Ranunculus, which grow coarse and leggy in aquariums. Ranunculus inundatus is characterised by its compact form and distinguished, deeply cut umbrellas. The plant forms many vertical runners with new plants and over time thick bottom coverage is formed. Good lighting produces compact growth. Long leaves can be pruned.
This plant’s rhizome grows along the substrate while each structure has one star-shaped leaf that develops on a stem.
Ranunculus inundatus in particular does require medium to high lighting to flourish in an aquarium. Low lighting levels lead to inhibited growth and taller leaves with long stems. As usual, higher lighting levels also require steady macronutrient and micronutrient levels from regular supplementation, as well as carbon dioxide addition. Otherwise this plant appears to be undemanding, adapting to a wide range of water hardness and pH values.
