So i acquired a 17" or so yarelli a week ago. Since then i havent seen him eat at all. I feed at night when the moonlight are on. Its in a 1500 gal with other fish as well as 2 rays that are no longer interested in it and leave it be before they would bother him since its a new addition and they are curious. He is in good health and does move around. The tank has a ton of o2 being pumped in and has several pieces of dw to hide underneath or next to. My question is how long have any of you seen urs take before it ate. I am offering it cut fish mainly since the rest eat it as well along with pellets but mainly cut fish for meat. Any input would be great. Ty
