Live Treats for Adult Fish

I'd like to give my fish a cheap, disease-free, live food that they could enjoy catching as a treat. My smallest fish is 1.5" and is one of my tiger barbs. I'd prefer one easy to grow and cheap. Is there such a thing?

 

Livebearers?

 

The thing is I don't have another tank I could grow them in. I was hoping for something that I could buy already grown or something that I could grow in a bowl or something along those lines.

 

How about brine shrimp?

 

Are you looking specifically for fish? what about worms? I feed my fish tubifex worms. There's also blood worms, black worms, etc. Maybe larvae? Most pet stores have live food for reptiles that would work for fish. I feed wingless fruit flies to by bettas.

 

Can brine shrimp swim fast? I'd like my fish to fell the thrill of the hunt if you get what I mean.

I should've phrased the title differently. I'm looking for a Live treat for Adult or near adult fish. Where do I get the brine shrimp? Worms would just float there right? Coradee Could you change the title to "Live Treats For Adult Fish" please?

 

I collect mosquito larvae all summer long from a tiny pond, also any bucket of water left outside. If you float them to match the temperature they give the fish a run for their money, albeit a short one. They're considerably cooler so if you just dump them in they kinda freeze with shock.

There's only fish fry really that will give them a proper chase.

 

I buy decapsulated eggs online. I'm sure if you let them mature they would be faster, but since I need the baby BBS for my bettas I don't let them mature.

 

How much is the brine shrimp? How do you grow them?

 

Depends on where you get them.

Decapsulated are more expensive than with shells.
It's really easy to hatch them. Just cut the bottom off a 2 liter bottle, stick the top with the cap ON into the bottom so it stays up. Put an airstone into the bottom so the eggs stay floating, follow the directions on the bottle for adding salt(mine had salt already added) and put a desk lamp under it. In 1-2 days the eggs hatch. I have no idea how to raise them to adulthood though.
