Firstly, I'd like to send you my condolences as I know it is very difficult to cope with what you are going through simultaneously. Keep your spirit up, it's like Murphy's law in action. what can possibly go wrong is in fact in play.. I don't want to say that that it's law of attraction if you worrying about which fish is going to have problems next. Keep your heart/emotions stable, it's part of the hobby. You are an excellent fish keeper, if not one of the most responsible ever on this board but there are things that happen that sometimes we can't account for. The hobby is meant to bring joy but if you feel like it's causing nothing but grief, then it's spiraling into a big tragedy one after another. It's hard to detach yourself when so much effort, dedication, commitment is at play.. But don't let it consume you bro. MFK community as a whole will be here for you through the hard times.
