Danio zebras, Goldfish and ghost shrimps

no ghost shrimp are soo small u can barley c them

goldfish get huge, produce massive amounts of waste (not just poop, but ammonia) and are coldwater. they require AT LEAST 15 gal EACH. most people recommend 30 gals each. i would recommend moving them to a larger tank by themselves, or returning them to the store. sorry, but you asked if there was anything wrong. that was one glaring thing i saw. other folks here will tell you the same thing.

Yeah, the danios are ok, and the shrimp are fine, but not the goldies (regardless of their species). They have much different requirements. If you didnt have the golds you could even get a few more danios.
Ive never had a problem seeing ghost shrimp, but they are clear-ish. Ive had some that were quite large, almost an inch.

yup, me either. even though ghosties are clear and harder to see than red cherries, they are lots of fun. they do all kinds of fun antics, like a couple of mine (father and daughter) would turn upside down at the surface to catch flakes. even though i've heard they "only live a few months" i've kept some that lived a year and a half. the females tend to be a big larger and longer than the males. the older ghost shrimp also are not entirely clear, but will develop red accents on the tips of their antennae and their legs. they're really neat, i would highly recommend them.

however, shrimps and other inverts are extremely sensitive to water quality and will be the first to die if you have ammonia, nitrite, or too much nitrate. never use copper meds with them, as those will definitely kill them.
