What exactly are the water parameters? And what are the full dimensions of the tank. I believe it's an overly crowded forty or fifty Gallon but I need to be sure.

Not a pro keeper but sorry bro, imho your issue is at least partially due to tank being way over-stocked for a 240l/65g tank with those kind of fish; not even big enough for just 1 Flagtail after it hits 8 or 9 months. Insofar as Xback not eating, it's new to the tank so not surprising, but overcrowding makes things even more stressful for most fish, so could also be why your stingrayaret eating.

And with the rate those fish (normally) grow, your water parameters might be ok now but soon it'll require almost daily water changes to keep up with the bio-load. I don't keep stingray but I know they require pretty pristine water.

So your choices are to get a much bigger tank, and/or re-home most of the fish, or be ready for problems. Just my 2 cents though, we all have to go the way we feel is right/best, good luck and update us later.
