Would separate till the endli puts on some size which it should do quickly.
Feed them (tilapia/pellets) and keep the water clean. Tank covered at all times.
Not too difficult. Keep an eye on juvi endlis as they can cannibalize other polys, esp small ones.
It is true, and hopefully no one will post a photo of a smaller poly being eaten as I'm not a huge fan.
8-10 inches isn't big for an endli - it can definitely happen at that size. But how big are the ornates? Oops, just read they're a couple inches smaller. I don't thiiiink that should be an issue... ?
Others with Endli experience will chime in.
