:help: I have a 75 gal. tank that I have had set up and running like a dream since July of last yr. I recently traded several of my ciclids for this big Texas something ciclid. Now all of the sudden he's sluffing (sp) and has been scratching himself on rocks and logs. He's not eating and has developed sores where he's lost scales. I also have 2 good sized catfish and another smaller ciclid that are swimming around like they've all lost their minds-seriously. Non of them are eating and one of my catfish looks like he's losing his color. I have changed the water, I've had it tested, I've done everything but nothing seems to be working. I am afraid I'm going to lose them all. Even my algae eater is swimming up to the top of the tank and then back down really fast like he's trying to commit suicide.:wall: My water is fine. The ph is just a little low. But I can't seem to get rid of the cloudiness.
