Hi all looking for a bit of advise got an American tiger datnoid(silver) around 2 month ago he's now about 3.5 inch been fine with feeding but will only take blood worms or cut up prawns and has always been greedy. I went away the weekend just gone for 3 nights came back Monday it fed but then rejected everything and now its day 5 with no food. My tank has been set up for a few years my water perimeters are all fine just small trace of nitrates it's tank mates are two small kelberi bass and a small flagtail which were all purchased together. How long can they go without food as I'm running out of ideas? There's no bullying in the tank if anything he is the boss and chases everyone and is still active and looking like he wants to eat but is rejecting everything . Anyone got any advise it would be appreciated thanks
