definitely a lot of issues with your stocking charts. we can help you if you want to change them though, and explain why things don't work in your lists.
for example:
Tank Size: 29 Gallon
# Community: 3 Blue Gouramis
# 3 Gold Gouramis
# 3 Bala Sharks
# 2 Clown Loaches
# 1 Rainbow Shark
the gouramis tend to be very aggressive to each other - since a 29 is a tall tank rather than a long one (lacking in swimming space) even a trio od one male and two females would be pushing it, just one would be better. bala sharks get waay too large (18") and should be kept in larger groups. same with the clown loaches - up to a foot long with schooling needs.
or this one for a 75 (?!)
# 5 Cichlids - what kind of cichlids? African? South American? Central American? Convicts? Angels? Oscars? Jack Dempseys?
# 2 Plecostomus (1-5", 1-8") - at least you give a size here, but without giving specifics most people will just get a common pleco, which can reach anywhere from 8-24 inches, completely inappropriate for any of your tank set-ups.
# 2 Eel loaches - ? I don't even know what those are. An eel? A loach? maybe a bichir?
# 2 African frogs - would be quickly outcompeted for food by the other fish, unless they are African CLAWED frogs rather than dwarf frogs. the clawed frogs will eat any fish that can fit in their mouths.
# 4 Black tip sharks - black tips are actual saltwater sharks. . . . what did you mean here?
# 1 Upside down catfish
# 2 Silver dollars - fine in a 75, but not with the others you have listed. also, a schooling fish that should be in a group of at least 3
# 2 Goldfish - goldfish. . . . first of all, they are temperate water, not tropical fish, and should only be mixed by experienced owners. they can grow anywhere from 6-14 inches depending upon the type. any cichlids in the tank would beat them to shreds.
