My 125 is not up and running yet,Ive had fish all my life until this year.I know all to well about loosing favs and sometimes total chaos in a tank.Has this became less of a problem with all the knowladge over the years by now?Could his losses been age related or fighting or what,because I want to get back into it since it will always be one of the biggest passions in my life,I dont want to be reminded of how awful it can be.I remember a time that no matter what I would buy for this tank already going would die.I know lots of reasons why this can happen but it really does get discouraging.My family would come over and ask about a certain fish and I would say well,its dead,yet some you couldnt kill.Is it better now than even 5 years ago?Is it the same old thing?Could the shops in my town just be getting crap stock.I hope this guy dosnt give up for good or on what hes got left but you cant blame him if he does everything right,Im not sure if he has.Any encouraging words would be nice because Ive seen a good amount of these threads since joining.Good luck man.
