It seems like everything that could go wrong has over the last couple weeks. One of my rescues died (although it wasn't a surprise, it was still hard), my boyfriend lost three of his tiger barbs in a matter of hours, Link (my only permanent and first betta) now has a problem that I can't diagnose, and last night my most recent rescue (who was getting better) started floating and not breathing off and on, so I'm expecting him to go at any time. All this death is taking a huge toll on me (as I have never handled it very well) and I don't know if I should just quit keeping fish. I know things happen, and that with taking in sick fish there is a chance they won't make it, but I feel like this is too much. Ugh.
