It seems I may have spoke too soon. Last few days they haven’t been accepting pellets no matter what I do. Today I tried flakes and they ate them. Would flakes and Krill be suitable?
Here are some natural light photos I just took. He has those bottom 2 teeth coming in and growing way faster than the other 2. There is one who looks similar to him with a little less orange and a little smaller he keeps hidden in the corner. There is also a white one much smaller with a smaller snout. My inclination is this is a female as he tolerates her presence. The other 2 are more skittish and tough to photograph.
