fish death unexplained

There's two platies and two corydoras of different species. There used to be more than that and now I don't want to look in the tank. I used to have a school of corydoras, but they all died off one by one to parasites I guess if that can kill them a day/a few hours after showing symptoms. A...

The point of this post is to see what you guys think happened. Keep in mind… I’m pretty new to fish owning. About 4 months ago, I got very into it and decided to get some of my own. I did lots of research on their necessities to taking care of them, gallons in a tank needed, how to know...

*Fish death* I got my first tank last week, and from the pet shop's advice I got fish on Saturday - just 4 glowlight tetras. It's a planted tank and things went well over the weekend, they seemed inquisitive, ate, played around in the plants and decorations I got. They seemed fine this morning...

Hi all, I could do with some help with one of my platinum lyre tail mollies. We noticed today that he is sort of floating on the surface. I say sort of because he does swim around, albeit slowly. He has his mouth partially open, but doesn't open and close it. He also isn't eating. It almost...

Hi there, I'm a newbie to the forum, and was wondering if anyone can help me out on this issue. I have had 3 fish in total now over the course of a couple of months, brutally attacked and killed. 2 of my sucker fish had their heads clean ripped off (none of the fish was eaten), and this morning...
