Same as what Sophia said but also if it is a fledgling and it seems well enough get it back into a nearby tree so the adults can find it. The longer you leave it the less likely the adults will accept it back. Good luck

So is there no one out there keeping or breeding the Hongsloi? Very much one of the underrated Apisto's. Superico.. Do you know if they have males in stock and do you know if they ship? Cheers
