So I've recently taken an interest in rosy red minnows, and have being trying to keep a 10 gallon tank of them. I started off with 4, and all but one died. I couldn't find the last one a couple days after that so I just assumed he went as well. That weekend (after 3 days after I stopped putting food in the tank) I discovered the lone survivor was still alive, if terrified and extremely skittish. I did a water change and fed him, but didn't manage to get him two more friends until 2-3 days later. That's almost a week alone after all his friends died. At first he came out and very insistently checked them out. I wondered if he was being territorial, but since they're schooling fish I put that out of my mind. Now he's hiding in his usual spot while the other two swim outside! I wanted to eventually go up to at least 6 fish so everyone could feel safe and happy, but I'm wondering if this is a bad idea and drive my survivor suicidal?? I had a scissortail rasbora jump the tank in the past because he wasn't fitting in with the others of his species. Does he just need time to get used to things? Should I rearrange the tank? What can I do??
