all water pream is good and normal which i dont understand why the fish still going down hill where as the rest of them is doing well as strange as it sounds it makes me wanna give up and i can t upload the video which is 26 secs long and it shows her swimming a spec backwards and then shoots forward then 90 degrees turn and does it again step back and shotts forward into 90 degrees turn and she keeps doing that .. im treating the tank half dose of parasite meds and its helping some and making other worst it almost seems like it got into their brains they got stupid and i also have a male that keeps falling sideways but he still eating and swimming so he find himself a tight spot to keep him self upright so hes trying to stay alive as well ... bad luck bad luck seems to follow me around
