There's a big difference between freeze-dried and frozen ANYTHING.
You're going to keep killing your fancies if you don't start feeding them a LOT more vegetable matter. Things like spirulina, fresh zucchini, spinach (give the land plants a brief trip into boiling water or a microwave to help break down the cellulose), frozen green peas squeezed out of their skins.
The problems fancies suffer can be involved, depending on just how 'fancy' they are. Bubble or celestial eyes, foreshortened bodies (fat, round), eyes set very wide all make ALL feeding for these fishes difficult. The fish don't "gasp" at the surface for food, they're trying to get it into their mouths. If you ever do find the fish gasping, you know you've got a problem (water too warm, too dirty, not enough surface agitation) because this is usually a sign that there's not enough oxygen in the water for them.
Brine shrimp will only add a bit of color, but are not worth much nutritionally speaking and, as you now know, can block their guts and cause....... wait for it.......!

Did you use any of the links I provided?

Ok, so, I guess loaches are fish that can be kept in a tank with fancies then, oh, and the bloodworms i have are freeze dried, so they keep floating, well, I noticed that my fantail eats it before it can sink, so I dont really know if the worms do sink or not.
You can take the freeze-dried bloodworms and press them on the inside of the tank
below the water line. They are not the same as frozen, and if you leave things like excess food in the water you're again causing yourself a lot more problems than you'd be solving by doing something like adding khuli loaches (or
any loach for that matter, they are a widely varied group of fishes and many become very large and VERY AGGRESSIVE. I'm not kidding about this).
I, and others who are knowledgeable, highly recommend
against putting any kind of tropical fishes in with temperate fishes, especially goldfish and koi. Pond dojos and the like would be more appropriate, but you won't need them if you feed the right foods, DON'T overfeed, and do your regular water changes.
