Post your water parameters? (even though you said you didnt want to)
Do daily/every other day 25-50% water changes. (even though you said you didnt want to do water changes)
Clean your filters out in tankwater at least once every so often. (even though you say you wont)
Buy a master test kit (instead of buying fish that will soon die)
Stop buying fish until your problems are sorted out (so you can stop wasting your money)
what buckets do you use to change your water? are they the same buckets that someone in the house may use for cleaning? you may be introducing some sort of toxin into the tank with your water change. fish (like humans) dont like ingesting bleach, ammonia, and other household cleaners.
Exactly how long was your tank set up before you started to have all of these problems? How did you setup your tank? how did you cycle your tank?
Did you make any major changes to your tank besides adding fish to the the tank? (eg: a major cleaning that day or day before or after, decoration scrubbing, etc...?)
do you have a sand substrate?
just trying to get more background informaiton from you so that i/we can help you
