So I have not said much that would be new to you
All reports more or less bear some truth and, hence, picture eupterus as a gamble, most likely to present mild compatibility problems, least likely to be problem-free, and somewhat likely to cause serious problems.
Asian syno? or USD catfish Mystus leucophasus? There are no Asian synos per se. They are all from Africa.
Young eupterus has stripes and does not look like an adult.
Synos, eupterus in particular, can live 25-30+ years proven in captivity so prepare for the long haul
