Iridescent Shark Diet

[CoryWM]

What size are yours, and what are they devouring? My IDs have barely put on any size, I've had them for 6 months. I seem to be able to grow anything else like it's a weed.

My 5 pack of IDs got upgraded from a 110g, where all they would do is swim in one corner. To a 300g, that is 6x5x18 inches. Now they swim across the whole front panel which is a step in the right direction, using 6 feet of tank instead of 6 inches of a corner.

I've watched them eat from the top, and eat from the bottom, but no feeding frenzy, seems no matter what I've tried so far, they don't love. Even froze bloodworms, don't seem to interest them more than anything else. I do have Juruparis, and a school of 30 clowns in there as well. Clowns may be scaring them off in the new tank. however in the 110g, They were the biggest fish next to some guppies etc. And still wernt aggressive eaters.

Any chance they're a social eater? Similar to clown loaches? Once 1 clown loach eats, all of them eat. Maybe upping it from 6 to 12, to get them to grow, then rehoming some later?

I've recenly ordered kensfish soft krill pellets, we'll see how that goes over with them. It'll be here in 2 days.

I grew my IDs first in a 180 then in a 420 once they reached 8". I've lost a few and sold/traded a few and kept just one of the albinos. He's grew from 2" to over a foot in his first year. The second year yielded only a few inches of growth. Now, at 4 years, he's 16-17" and still growing, albeit slowly.
Diet consisted on just about anything thrown into the tank. He's fed on dense culture crumbles, salmon pellets, ken's sinking sticks (a variety of them), frozen bloodworms, krill, plankton, chopped earthworm, clam meat, mussels, crayfish, shrimp, etc.
As a single cat, he doesn't hesitate to get his share from among the dozen polys, trop gars, AUL, and afaro.

Awesome, gives me hope. One more question for ya, Does he prefer to eat from the top or bottom? I know almost all fish can be trained to eat either way. Just kind of a survey of sorts.

they will eat from the top or the bottom.depends on what you feed them. mine eats from the top and the bottom at the same time.

Mine prefers to feed from the bottom to mid-water.

I got a friend with a 2+ lb ID, over 2 feet long for sure. All he eats are sinking veggie discs I believe.

My guy has grown about from about 7-14+" in about 6 months. He was living in someone's 30 gallon tank, and I rescued this poor guy and upgraded him to a 180 and he will soon be going in a 600. He's lived on Hikari massivore, sinking cichild gold, random algae wafers, chunks of shrimp, krill, and tilapia. I keep him in water that is about a 6.5 pH and because of all the catfish in there, the water is changed at the very least once a week.

When my tank lights are on, my sharks keep swimming up and down, with there noses pressed against the glass, for hours....Whats up with that.

All of my young ones did the same thing. They'll calm down as they mature.

My ID is about 12 years old and about 14"...he is extremely picky when eating. Sometimes he likes floating pellets and flake, then won't touch them. Sometimes he likes sinking pellets, krill or regular chunks of shrimp. He always keeps me guessing. Anybody else go through the same thing.
