Soft Hornwort
Ceratophyllum submersum
Family: Ceratophyllaceae
Soft Hornwort is the more delicate relative of the common Hornwort (C. demersum) with even finer, softer leaves. It floats freely in the water column, requiring no substrate or roots. Grows rapidly and absorbs ammonia and nutrients aggressively. Excellent for cycling tanks, fry tanks, and shrimp tanks where it provides cover and nutrient absorption.
