This was the stupidest mistake ever: I bought a knight goby and some feeders from my LFS. well against my better judgement he had ich. but that's not the mistake. i put it in a 1g temporarily to treat it with the feeders for quarintine but when i got it from walmart they said it was 2.5 gallons so i put 2.5 gallons worth of meds in. long story short (not really) he was dead in the morning

I have silver dollars and a pictus cat from there that are alive and well.
