Old Tank Syndrome
 

I found this article after losing my third fish this year after years and years of fish keeping. It answered all my questions and is well written.

Old Tank Syndrome

as someone who is still "on the honeymoon" it is sad to think of losing the enthusiam for fishkeeping as suggested in the article :( good information though.. more detailed than anything i had read previously about old tank syndrome

I'll kepp this in mind, who knew? Ironically my ten gallon needs more water right now :p
