my african cichlid (red zebra) has grown in size and was eating well then stopped eating I had changed its food to a variety of shrimp, beefheart, and squid as well as pellets. I have her in a brackish setup with two columbian catfish and a G. tile eel. the tank has a SG of 1.016 and all tank parameters are stable. She has red spider veins showing behind her scales and would hide vertically face up behind a filter every now and then for a few days. I recently added a wet/dry filter as well as some drift wood from a beach about two months ago. please help!!!
