I'll try to keep this long story short, just skip to paragraph 2 to skip the background. I have a 250 with an Oscar, yellow lab, firemouth, and two common pleccos. For three days around Valentine's day our power was out and the Oscar was pretty much gone, water down to 50, might have just put him to sleep, I don't know, but he was floating upside down completely listless. The water heaters came back on and he made a complete recovery within 5 hours. Sometime the next week I was talking to my friend about how nice it would be to have native fish which wouldn't need a heater. So about 2 months ago my friend decides to surprise me while I'm out of town and put 7 bream that he caught in the tank. There were two warmouth, I think a green sunfish and 4 who knows what in there from Monday until I got home Friday night. I cussed him out but made the mistake of saying you could have at least got me a redear. A month later amazingly only the larger warmouth had died, he never took pellets and the green started bullying him. Anyway it's Tuesday about a month ago when my friend strikes again, a redear and another I couldn't ID which had fungus all over him. My wife calls me Wednesday, two dead fish. Had her treat with polyguard. Thursday, three dead. Friday, two more. She said the dead all had fungus on them, but the original fish with fungus was still alive. So when I get home all of the original fish (o, lab, firemouth...) have no symptoms at all, one bream no symptoms, one looking like it swam backwards through a cotton field. I quarantine him and continue treating for three weeks, finally better but still quarantined. So here's where it gets weird...

I'm cleaning the sump on the 250 last week and see a tiny (1/2" max) fish in the third chamber. I thought it was a male mosquito fish I had given to the Oscar earlier in the summer and brushed it off. This morning I'm changing water and see him again, this time bigger and definitely not a mosquito fish. I put him in my 55 with some platties and mosquito fish, curious to see what he turns out to be.

He's really shy so it's hard to get a good pic, will try again tonight.

Not that I noticed. It really doesn't make sense. None of them should have had time to pair. The one that was being aggressive is the one that's left in the 250, and the fungus ridden one, but he's been in qt for a month.

Interesting story, sounds like you need to sit down and have a talk with your friend though, and explain the need to quarantine new fish. Then show him the quarantine tank and how to set it up for the next time he decides to surprise you.
 
Will two things.

1) if there was no nest they probably didn't spawn.
2) sunfish don't pair, the male makes a nest then several females spawn with him, only the male cares for the eggs and fry.
 
That little guy(?) is dangerously close to the crayfish.

I'm thinking your buddy threw him in there as well
 
If you mean he threw the crayfish in, that was me. I give one to the oscar now and then. If he did throw the fish in it would have had to have come from the live well. He caught them with a bream buster and dipped them from the live well with a bucket. I guess it's possible.

This is the lone survivor in the 250 from the original 7. The mouth looks funny because my firemouth decided to sneak in behind.

And this one had the fungus that killed all of the others...
