So yesterday, everything was fine. Today, a dead fish that looked like it had the guts vacuumed out of it. My aquarium is a 20 gal and the ph is 8 and the nitrites and nitrates are at an average level. I guess the algae eater was kind of bloated but it has been that way for over two months. I assume it just feasted on my plants and algae. Now tonight I find his body and it looks like its been vacuumed. There is a red area going through the middle of only one side of his body that wasn't there before. The wounds below his fins was probably done by the snails or the minnows. He did have reddish swollen gills last week, but i'm totally out of ideas of what could've killed it.

I don’t think that something killed it. Most likely, it died and was scavenged.

What’s the rest of the stocking?

What’s the exact ammonia, nitrite, and nitrate level?

It sounds like an improper diet caused bloat and then was scavanged after it died. There’s no average level of nitrite and nitrate, but you’re also forgetting ammonia. So a properly cycled tank will have 0 ammonia, 0 nitrites, and usually 5+ nitrates. Nitrates should remain under 20ppm via water changes or plants. Any amount of ammonia or nitrites can cause death. I’m assuming that the store didn’t inform you that your Gold Algae Eater (Chinese Algae Eater) can reach up to 12 inches and become very aggressive. Sorry about your loss, I hope all your other fish are doing awesome!

I have two adult angelfish in there that were raised from babies, and they look like they are doing fine.

They only told me that it grows to maybe 2.5 inches.
