What fish should I put in my 75 gallon tank?
Cichlids are some of the best freshwater fish to keep in a tank of this size. 75 gallons offers plenty of space for each Cichlid to establish their personal territory. You can have a few Convict Cichlids, Jack Dempseys, freshwater Angelfish, and a pair of Oscars. Goldfish thrive in a tank this size too.

How many angelfish can I put in a 75 gallon tank?
In a 75 you would be fine with 4-6 angels as long as the tank has decor (driftwood/rocks/plants) where any bullied fish can get away with the aggressors. If you went with a 135 gallon you could probably keep 8-12 angels give or take depending on temperament.

In most cases, a 2-inch layer of gravel will look rather thin in a 75-gallon tank. Most people with large tanks prefer to have a substrate layer that is 3-4 inches deep to fill out the tank. Which means you may need upwards of 224 pounds of gravel to get the look you desire in a 75 gallon aquarium.
Can rocks be too heavy for aquarium?
The heavy rocks should be okay and the foam will keep any points of the rock from breaking the bottom pane of glass. Many people in our club put egg crate on the bottom of the tanks before adding the substrate for this very reason. It helps to distribute the weight of the rocks evenly along the bottom glass.
How many rocks should be in a fish tank?
Generally speaking, you should add about 1 pound of substrate per gallon of water. This means that for a 5-gallon fish tank, a safe bet would be 5 pounds of gravel. Similarly, for a 20-gallon fish tank, roughly 20 pounds of gravel would suffice.
Can I keep just 1 angelfish?
A single (male or female) would be just fine. Most Angels are just fine with other species as long as the other fish stay out of their breeding area. A single Angel will not have a breeding area, so that is OK. The fish you list are large enough not to get eaten.
