please help my fish seem to be dieing off one at a time and i dont know why. i was kinda getting lazy on the water changes but ive been getting on top of that again. first i lost 2 huma huma triggers now my clown trigger is having the same signs witch are signs of weakness then hiding behind rocks not eating then they kick the bucked. the clown seems to be losing his color as well
i dont have a sick tank so what should i do or try to give them. im about ready to give up
