Fish only 5 gallon stocking suggestions?

[ZachG]

I got a new 5gallon tank today and have been keeping freshwater fish for many years. I thought today that it might be time to start a saltwater aquarium. The first question I have is if there are any beginner fish that could live in a five gallon and will I have to start a new cycle or can I use media from my freshwater tanks? I’m In need of a guru.

Not sure any saltwater fish should be kept in a 5g. If this is your first saltwater aquarium a larger one would be easier to keep stable.
You can try invertebrates

Some resources say these can work but I think would appreciate more space:

.1 Clown fish
.1 Royal gramma

The only fish I think I read will be at home in a 5 gal reef or fowlr would be the small gobys such as:


. 1 Green banded goby
. 1 neon goby
. 1 Clown goby
