I have a 250 gallon tank with a 75 gallon refugium. I run RO water and have 2 PJ sharks, both about 8 inches. I've had them for about 5 months now and one of them is suddenly not eating, sitting around all day as opposed to being its very active self and has a reddish swollen like anus. I feed them Silverside mostly, and clams and squid every once in a while. All water tests are normal, but Nitrate is a tad high 30ppm. Im doing a water change tonight. I love these sharks like kids and id hate to loose one. Any help would be greatly appreciated. Thankyou
