I’ve had this guy in a nice observational qt for a few weeks. Cycled. Lots of live rock. Crushed coral substrate. 55g w inverts and 1 other fish. Goby was nice and Fat. Not shy at all. Great appetite. Other fish started flashing. Both fish got moved into a 20g treatment tank. Bare bottom. No live rock. PVC pipe. All general equipment (heater, HOB filter, lights). From day 1 in new tank, goby has stopped eating. Not doing much of anything. Still fat cuz it’s only been 4 days so far. Copper ramped up slowly over 4 days. Other fish doing fantastically. Goby never showed symptoms. What do I dooo?!? I can’t let him starve for 2 weeks. Already soaking food in garlic guard to stimulate appetite. Feeding all his favourite foods. Getting food to land perfectly right in front of his face. Nothing!
