i have had the same lightly planted 5.5 gallon tank for my male betta for about a year. i tested my tank this morning out of curiosity and the ammonia was 0 and my betta was happy and healthy looking. i went out came home 5 hours later and my fish is almost white laying on the bottom of his tank. So i test his water and the ammonia is off the chart over 8.0ppm and deep deep blue. I do water changes every week don't overfeed and have no dead plants i am dumbfound. any ideas?
