thats sad to hear that the last one didnt survive
we all can make mistakes in fishkeeping, we have all lost fish along the way, and have felt bad when its happened.
Best thing you can do is a lesson learnt, and try again,
recycle your tank, dont throw out the media etc, it will have some beneficial bacteria on it.
Cycle your tank well, and get the recommended number of fish for your tank.
Soo many wee fishies out there need a good home!
you didnt deliberately kill your fish, and you tried very hard to save them
some things arent meant to be i guess,
good luck in whatever you decide, and I hope you do try again..
