(zebra danios in 20 gal tank)
Please don't lynch me, guys. I was impatient and now I've lost four fish because of it. I made the classic mistake. The dumbest one in the book.
I bought three new fish and put them in my tank of two almost immediately.
They've slowly been dying off, without even showing clear signs of illness. I have no idea what to do, or how to fix this situation.
I've begun decontaminating everything in the tank by removing and scrubbing. I set up a quarantine tank and put the newer of the remaining two fish inside of it. The older fish is still in the tank which has only gravel and a plant. My question is whether or not I should put them both together in the qt tank and finish scrubbing down the older tank.
Again, I'm sorry for my ignorance. I'm really not looking for a lecture. I just need to know what to do to keep these fish alive.
I can include pictures of the most recently deceased fish if needed.
