Last fish died :( now what?
I have a ten gallon tank that I have had 3 1-2 weeks. I fell for the lie that you can buy fish after letting it run 24 hours. I bought two fish, a snail, and a ghost shrimp. After the neon fish died that night, I found this forum and learned about the cycle. I still need to get back to the store to buy a kit, so I cannot test my water, currently. The snail became less active after the first day. It died almost ten days later. It had strings coming from it. I added three baby Mickey Mouse fish that a friend gave me. They too became stringy (poop, I think). I posted last week to see how to treat for a parasite, and someone said it sounded like nitrate poisoning, not a parasite.
Anyway, all of this to say the final fish is 99% dead. So what do I do? Do I keep cycling the water that is currently in there? Or do i take everything out, clean it, and start over?
