I used to keep fish when I was younger, but they'd often die after about a month or two. I would try to treat the water, change it, add plants, take out plants, fiddle with the filters, all to no avail. After a while I thought I just sucked with fish, I'd always be amazed at the people who seemed to have some knack for keeping their fish alive past a month, so eventually I quit trying and gave the tank to my brother. He started to have the same 'bad luck' as I did, a pet fish he had for year or two died a few months after it was put into this tank, then a pet lizard after that. Nothing would stay alive. After a while me or my brother came to the conclusion that the tank itself must have some poisonous chemical or residue (probably in the glue or sealant) that was killing whatever was put into the tank, he (being a better fishkeeper then I) couldn't even keep his critters alive in it. Sometimes this happens with tanks during their manufacturing, and it happened to be that I ended up being the unlucky recipient of one of these.
Hope you don't ever find out you got one of these tanks during your first aquaculture attempts. They are such a motivation killer if there ever was one.
