Sorry to hear about your aro, i know how you feel i lost all 3 of my aro's last winter when the power went out for an extended amount of time.. You just need to jump back in the aro game and pick one more up, that what i did and i felt much better..
Really sorry for your loss bro, nothing worse than loosing a fish you have grown yourself and have really cared for. Try and look on the bright side and have a think about what fish you have always wanted to keep that could go in the space the aro left.
