It is possible that the other fish injured the subject fish, BUT IT IS ALSO POSSIBLE that the fish with the "hole" had a skin infection which killed the tissue, and as the dead [necrotic] tissue decomposed it "washed away," leaving the hole.
Fish often get swim bladder. Which effects the balence they have. Sometimes it doesn't affect them in any way other then the side floats. Other times it can kill the fish sooner then later.
Lamprey, hagfish suck body fluids from the host fish after rasping a hole in the side of the body.
Mostly, community fish. Angels tend to be a LITTLE on the aggressive side, but are not that aggressive so, I suggest not putting your angels with other aggressive fish, as they will probably fight or kill one another off...

a black hole is not actually a hole...it is a super dence point whose gravity is so powerful it pulls everything into it
If you mean the 'other side' of a black hole, we don't really know. The other end of a black hole could be a rabbit hole, spitting matter into a parallel universe. Or perhaps there is no other side and matter is simply gone. Many believe it is possible that black holes could be gates into other universes or parallel worlds. However, since we haven't thrown anyone into black holes, we don't know what lies on the other side.
Why did hitler kill himself. For real
