live food??

Well it depends in the kind of fish you want to feed. Daphnia, earthworms, grindal worms, and vinegar eels are all easy to culture. vinegar eels are too small to feed anything but small fry though.
 
well i got 150 gal with oscars and red devils and jds 55 gal with black convicts yellow labs 2 little jds bubble bees 55 gal with mollies and a few gourmies
 
mosquitoes

Put a bucket of water outside and watch for mosquito larva. Happens pretty fast around Houston -- just be sure to harvest before they start biting people!
 
You can certainly grow infusoria, though I don't know what good it would do for your fish. It's a very small microscopic food for fry. I'd go with earthworms. your oscars and other large cichlids will gobble them up. Maybe set up a 15-20 gallon guppy tank too, with a lot of fake plants, and then you'd have some clean parasite free feeders. That's a high maintenance type thing though, one more tank to change water in and you have to feed them often etc etc.

For the smaller fish, grindal worms would probably be good, along with tiny earthworms. You can get starter cultures for decent prices at www.aquabid.com I have vinegar eels I could send you, that's it though.
 
Easiest way- I buy live blackworms every month from Aquatic Foods. Everything I keep gets them and loves them- from Discus to ghost shrimp to Cardinal Tetras to Goldfish to Clownfish and my anemone.
They are easy to keep (in your refrigerator) and last a very long time.
