If both these fish make it…you can only have one per tank, and it must be a big tank at that. I personally only bring home healthy specimens that I went looking for and done my homework on. These are not kittens and puppies. Now your QT is tied up with two fish you don’t even really want.
I understand your compassion, once my sister and brother in law went fishing and caught cat fish. They came in the house and held the poor things up on a rope to show their catch and then placed them in the kitchen sink.
Two hours later I went to the kitchen and happened to look in the sink, there was only a tiny bit of water it didn’t even cover them. They were out of water and gasping for breath, I thought poor things not only are they in an alien environment, they had to endure listening to the family jabber about how they will taste so good and couldn’t even be comfortable to breath. So I turned on the water to let them swim free in the sink..
My sister caught me and asked what I was doing, I don’t know why, and I felt pretty silly but I choked up and cried as I explained I just wanted them to be comfortable before they killed them. They had a good laugh at my expense, crying over a fish. I had big freshwater tanks at the time and I yet wouldn’t take them home and try to keep them. Because I “rescued” a carp once, putting it in my big Goldfish tank and it killed everything in my tank because it had a parasite called hook worms.
