Mine died with no known reason to me... ? The only thing I can think of is a diseased feeder platty? No idea man.. All my water parameters are superb.. The thing is the platties have been living in the tank for weeks in pretty heavy salt. Well recomended salt to treat ich. But before the pike got in there either one or two water changes were done so I really have no clue. There is a tiny jardini, some red hooks and lemon barbs living in there now with no signs of any distress. It really sucks... Oh and he ate that endli that I posted in the picture..
