Hello I have a full size adult engineer goby-have had him well over 1 year. I just upgraded from a 90 gal to a 180 gal tank just under 2 weeks ago. Prior to the move he was eating plenty every day...I feed him off a stick every night...since the move to the new tank I cannot get him to eat off the stick...the food is right in front of his face and he knows its there but wont touch it...I even leave chunks on the bottom for him and remove the stick and back away but he still wont eat them...I don't know if he is eating or not at this point but he seems healthy and is digging tunnels and peeking out of the rocks...I assume he has to be eating something to still be alive...any ideas? I don't want to loose him. Thanks.
