Olivier - would it help if some of us came over one day to help with the tank? I mean you can't go from asking me how to breed clowns to the other extreme of saying good bye to everything. let me know. Be happy to come over and help with anything.
The only maintenance I do with my tank is a 40 gallon water change every other week. And then feed them of course but even that I forget to do every day. Probably helps to keep from them getting obese. And of course filling the top-off container once a week.
If we can get you to a point where you are doing just a few things for the tank - I'm sure it will become far more enjoyable for you, wife and kids, rather than the burden you are now seeing it as.
+1 I'm there at the drop of a hat.
