I have my Harlequin Rasboras and Cories for about 3 months now, and a couple of weeks ago, I added a couple of Guppies (I used to have a Betta in there, but now he has his own tank.) All of my fish were fine, until one of my guppies just died today. And I don't really know why. He was fine this morning, and when I fed them, all of my guppies had the same appetite as they normally have. And then, about an hour later, one of my guppies was just lying dead on the bottom.
I checked the guppy for any signs or spots or injuries, but I didn't find anything. The only thing that might be something, is that I caught one of my guppies rubbing against the gravel yesterday, but he only did it once, so I'm not sure if it is anything, or if fish just do that sometimes. Looking at my other guppies, I've noticed some of them doing it as well, but most of the time they're just swimming around the top or middle of the aquarium.
The Guppies did change a bit in color. About 2 days after getting them, their bodies became quite a bit darker, but I assumed it's because they were stressed in the store, so they were very pale, or maybe because of different food, but now I'm just second guessing everything.
On top of that, one of my Rasboras has a damaged fin. It happened this night, he was fine yesterday evening, this morning his right fin had a big bloodred spot, and it hangs a bit limp. I'll add a picture. (The spot is really close to his gils, but his gills are fine.) I assume it's because he fought or was attacked, but I'm not sure which fish did it, since I've never caught any of them being agressive (I have online classes, which means I spend a lot of time in my room looking at my fish instead of paying attention, so I assume I would have noticed if there was fighting or chasing or nipping at fins.) He swims fine though, if I'm not close enough to see the red on his fin, I can't tell which of my Rasboras is injured just from their behavior or swimming. I'm pretty sure it's just an injury, but I do think it's strange it happened on the same day.
Water parameters are the same as they usually are, ammonia 0, nitrite 0, nitrate less than 10.
I did a partial water change sunday, and accidentaly turned the dial on my heater down 2 degrees, so I adjusted that a day later, but I don't think that's related?
I'm trying to figure out why my guppy died, and if I should be worried about my other fish as well.
