yesterday my red betta kicked the bucket, but there is something really werid. i usally feed the tanks around nine or ten in the morning, well i was a late yesterday and i thought about it and it was like noon, well at like about two i remebered i hadn't feed my two ten gallons so i went into my bedroom and found my red betta almost completely white and his fins all gone?!?!!?! and he looked puffed out, i thought at first malwi bloat, but there are other critters in the tank, wouldn't that affect them too? all i know is that my betta was very argant, he always pranced around the tank, and the past few days he just sat on the bottom, not like him at all. anybody got any ideas as to what killed him? thanks
