How big have you found S. leichardti get in captivety? Since I'm staying away from the Asians Arowanas until they are legalized I have been considering S. leichardti for quite sometime (since 95 actually). How big have you grown them? When mature do they change to adult coloration unlike the juvenilles coloration? As well how similar are they to S. jardinii in captivety? Are they an aggressive fish that can be kept with other aggresive fish or do they require a specimein tank (kept alone). I've got a 100 gallon and a 360 galllon I' considering redesigning.
