I have owned my Green Severum for about 4 years now, and while he's
always been a picky eater, lately he's just gotten worse.

If a fish is being that picky it could be a sign of a greater problem. Is
the fish exhibiting any other outward signs of stress or disease? Are your
water parameters on spec?

You can try feeding him nutritious frozen foods like shrimp, bloodworm, and
krill--if he doesn't have any interest in that than there is probably
something wrong with him or your tank.

Healthy adult fish can go for several days without food without any
repercussions. In the wild fasting is normal as food is not necessarily
always available. It may take several days of fasting before the fish
takes a liking for other foods. Some large predatory fish sometimes go a
week without a meal.

I have had adult flowerhorns in the store that came in refusing to eat
anything that wasn't alive. By the time they sold they would happily
accept frozen foods and would grudgingly accept pellet based foods. These
were $400 and up fish; it wasn't easy on the conscious to let them go
without food, but in the end it worked to everyone's favour.
