I consider myself an expert reefer but it’s time where my knowledge is just not enough. I need some super experts opinions. I have 2 things and I’m going to start with my first situation. So recently I picked up a banded pipefish, this is in a 13.5 gallon tank to grow him out as a baby, the tank is extremely mature being over 3 years old and home to my mandrin dragonette who has successfully been trained to eat frozen foods. But I’m trying to teach it to eat some sort of frozen to supplement his diet but he seems to ignore even my live pods. I grow my own pods at home and I have some tigger pods aswell to try to train him that the pipet means food. But so far he won’t even eat the live tiggers. He only wants the ones on the glass or just ignores food Al together. My chemistry is almost perfect and I’ve had no chemistry fluctuations for a long time. If anyone had any tips or experience with these little guys I’m open to all suggestions. My second situation is in my 40 gallon, in order to make space for the pipefish I moved over my yellow watchmen goby and he seems to like the space but he won’t eat anymore and I’ve had him in the 13.5 for 3 years. Idk if it’s just he needs to acclimate but he just ignores the food. The other part to the situation is regarding my starry blenny. He’s a massive dude being at 5.5 inches or around 5 I’ve never really measured but he seems to have gotten slimmer over time and he won’t accept foods. He spits out the spyirolina brine I give him and he has showed less interest in nori and algae wafers than he used to. He is breathing pretty fast and usually when I see this it means the fish is soon to pass but I want him to survive cause he’s a incredible specimen and he’s one of my favorite fish. If anyone knows how to help with these situations I’m open to all suggestions.
