Sorry, I am grumpy this morning, sinus headache.
More info, they grow pretty quickly and a 10 year old should exceed 5' long, they will need heavy brackish or full salt by then. The coloration of adults is a dull mottled brown. they are very easy to feed and will take pellets, chunks of fish, clams, shrimp, etc., Ph is on the alkiline side, dH and salinity is variable but as they age they need conditions that more and more approach seawater. Not easily sexable even as adults, Not known to have been captive bred. Suspected to be pelagic egg scatterers. Temperment is semiaggressive towards similar fish, eats smaller ones. Temp. is sub-tropical to tropical so anywhere in the 70s.
