what are fish/inverts that don't lay eggs, so far iv'e got cherry shrimp (carry there eggs) and endler guppies (a livebearer ofcourse). There is got to be more fish that don't "lay" there eggs?.

Yep. There's tons of em. Freshwater stingrays are livebearers (need a BIG tank tho & sensitive fish, careful)
Guppies, molly's, sailfin molly's, golly's, platy's, swordtails, 4 eyed fish (Anableps anableps), freshwater pipefish (very difficult to feed and sensitive, requires live copepods to eat which you must culture yourself and cannot buy. Cannot be trained to eat frozen food and prepared foods are simply out of the question. Rare and expensive. Known for being so picky they typically will starve themselves to death before eating anything but copepods. Comparable in difficty level to the famed saltwater mandarin dragonet.) Many more tho that's just off the top of my head. Also if nothing else a good google search will provide many species.

The guppies, mollys, platys, and swordtails are the most common livebearers. Keep in mind that guppies can cross breed with Endlers and mollys, and platys and swordtails can cross breed with each other.

Another livebearing invert is the Malaysian Trumpet Snail. Scroll down to Life Cycle for details. They actually do lay eggs, but then keep safe them until they hatch.

Seahorses do something similar: The eggs are stashed in the male's special pouch.
