i think my pleco are sick but i dunno what sickness they have ? they usually hide in the dw or staying at the bottom but this few days they are at beneath the surface, some staying at the top of the dw. i thought they are fine. yesterday, one of them turn pale, other 2 got white patch on their eye. one of them eye look sunken. their stomach are fine, no sunken. so i did 60% water change but it does not help. all my pleco got different symptom so i dunno what to do ? ph is 7.5. i dun have a nitrate test kit but my water is crystal clear does it mean water is good ?
any idea what sickness they have ?
