Okay I know this sounds stupid and everyone will say I'm stupid but please don't just ridicule me on stuff I already know and just provide your insight.

So I have 3 cory cats for about a year now, two are bronze and one is emerald green. They were originally in my 60 gal with my angels and my arowana that I was growing out. (NOW HERES THE PART WERE EVERYONES LIKE NOOO U CAN'T HAVE CORY'S WITH AN AROWANA IT'LL EAT THEM AND CHOKE AND STUFF) well mine have been there with the arowana for 1 year no issue except for one thing. This has recently occurred and been occurring for several times now. I don't know what it is and I'm very confused. I keep finding my smallest cory about an inch and a half with its back tail damaged up to the actual tail and the top fin is also damaged. At first I thought it was my arowana (which surprised me because its extremely shy, has eaten pellets all its life and I've never seen it target them). So I took the little one out and it recovered in a month in a seperate 2 gal and then I monitored the other two cory's and they were fine. Never touched by the arowana. So I moved the little guy back in and about 3 weeks later i found it injured again. So i removed it and it healed up again in no time and then this time I just upgraded to a 150 gal for my arowana and angels and inside already was a JD and a BP. So rn its all those guys and my cory's were doing great until today I found the little guy injured again so I moved him back to its isolation tank. What is the issue here? It gets plenty of food, hiding space, water levels are great, and nobody large is evidently picking on it. What could the issue be. I can't be the arowana or JD because both are big enough to swallow it whole and they would've died from the cats barbs. The BP is too slow and can't reallly nip fins it just pushes. So that leaves the angels and the other cory cats? Could they be the issue. Cory's are very kind and they love it every time the little one rejoin there group. Please tell me what the issue could be so I can permanently fix it.
 
What a well-asked question. Much can be learned from reading your question alone. Thanks for that. Still, a clear photo might help understand better what the injury keeps recurring.

But at the face value, one or more of the current predatory or territorial tank mates are not suitable for your little cory. As simple as that and you already know it, it seems.

When i had cories in a 120 gal with a lot of larger tank mates, like 3"-4" TSNs, I started seeing the same thing - they would get roughed up, most usually at night, in an evident attempt to prey on them. The predators were persistent and kept trying, eventually wiping out my cories. There were 50+ different tank mates, mostly catfish, and most of them predatory.

Moreover, just because a predator is accustomed to taking a certain feed, like pellets, it does not mean the predator inside that fish has died. Just like with many animals, as small as little catfish and as large as a tiger or a lion, that predator comes out "to play" one day and someone pays the price.

I know this is no revelation and you know it. It was merely noteworthy.
