Hot Rod (the betta in my avatar) passed away today at only 9 months of age!!!
5 gal. tank filtered (cycled) & heated to a steady 80 degrees, live plants, Prime water conditioner, 50% PLUS water changes twice a week, good quality diet (New Life Spectrum & Golden Pearls), one fasting day a week. Cleaned his filter sponges twice a month in used tank water. No water parameters since I used up my testing kit years ago & never replaced it.
NEVER a moment of worry with him till yesterday morning when he was "sluggish" about eating, but did eat some. Just Wednesday afternoon he exercised with a mirror for 5 minutes and after that was SO proud of chasing off that "other" fish, he patrolled his tank showing off for another 5 minutes or so. Today - DEAD!!!
Yesterday when he was slow to eat I did a water change & added a whole IAL - to no avail.
NO signs of injury, illness or parasites.
I just don't get it!!! ANY ideas of what I might have done wrong?????
