Here is the peaceful group. All fish featured in this post are the best community fish one can find. They are also all very hardy*
The blue-eye cardinals are not rare, but they are also not very common in stores as they are one of the pricier cardinals. on the other hand, the bangaii cardinal is almost reaching goldfish status in saltwater (the percula clown already has). They are hardy, peaceful, and very easy to breed. People can often rear young’s in their tanks since they are mouth brooders.
The fire fish are elegant, and fun to look at. They are also very peaceful and hardy- so peaceful that you must not keep them with any aggressive fish, especially with an open top tank, because they can “fly” out of the tank with ease.
The ranfordii Goby is inexpensive, cute, low maintenance and hardy. I put an asteric on the word hardy previously because they do have a specific requirement- You must have sugar grained size sandy bottom as their main diet is filter feeding the sand. Crushed coral and larger grain aragonite sand won’t do because they cannot take it through their gill.
