Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 2.0 cm CL male/unsexed; (Ref. 107481); 2.325 cm CL (female)
It is found on pneumatophores and roots of Avicennia marina (Ref. 107904). Active during low tide, but many are observed at high tide moving to mangrove roots above water level. Also lives among roots of Rhizophora mucronata. Feeds on mainly on macroalgae, a bit of mangrove leaves and mud; animal items were rare but may be an opportunistic feeder to a certain degree (Ref. 108401).
