The Taffy Apple
Fish Herder
I, also, was given bad advise from a LFS chain store when setting up my first (30L) tank last year. I bought Mollies after the tank had 'settled' for a week. They died within 9 days. I went back, he apologised, sold me 6 guppys and in they went. They died after 14 days.
I would simply say you didn't understand the benefits of whatever bacteria was in the cannister before you 'cleaned it out with tap water'.
Not the end of the world i suppose, either do water changes to keep the Ammonia below 0.25, or do what i did.... i cut my loses, logged onto this website, then carried a full 'fish-less' cycle, my tank is now sitting pretty in the corner.
Hope this helps from a fellow new hobbyist,
Terry.
