I have had two manderin gobys that I have had for over a year in my 120 gallon reef tank. Today I had the male litterally die in my hands. He looked like his stomach was non existent and concave. I caught the female and she had the same concave stomach. So I put her into the sump where I have thousands of coco pods,anthropods, and yes baby shrimp that seem to be growing on their own. My question is have anyone had this happen to their well established gobys? And how long would you guys keep her in there so the main tanks pods will repopulate.
