Hi Carrie,
They are a fun species. You will definitely need a chiller. Do not attempt to keep them without one. They do best at about 66 degrees.
2 pair in a 75g should be just fine as long as it is tall enough.
Catalina Gobies would make a great tankmate. They are temperate. They are very colorful and will do well at 66 degrees also.
Some of the macro algaes would do well. In terms of corals there are not really any commonly available species that do well below 72 degrees.
HTH,
Leslie
