First post in AGES, and its a negative one I'm afraid.
I have a platy that I noticed had a lump on its top/side fairly noticeable, the scales are poking out slightly where the lump is. He is one of a trio, there is a pair that get on fine and both harassed this one, so no doubt the stress has weakened him and he's got some bacterial infection or something.
So yesterday I get home from work and he's swimming around in circles on the substrate, on his side/upside down, then rests for a while then he was circling around higher up in the tank, then back on the substrate.
this morning he was upside down in the one spot and hasn't moved all day, he's upside down and only occasionally moving one fin on his side, looks like he can't move at all. his gills are still going, could be fast or might just be normal its hard to tell.
I am pretty sure he is going to die, and to be honest I was hoping it would of happened by now but the little dude is holding onto life for some reason.
What do I do?? I do not have a QT or hospital tank so putting it in such is a no go. I also am no dispatcher of fish, or any animals to be honest, I have read different methods of putting a fish out of its misery, which this thing must be in. I have heard of using clove oil, or putting it in the freezer in a bag of tank water, or chopping its head off and destroying the brain........ all things I don't WANT to do.
What is your advice on this subject. I kind of want nature to take its course, but I also don't want the thing surviving for a week upside down and starving to death.
I will attach a photo.
All the other fish are fine.
