Nocturnal?

I'm having trouble finding out what kind of nocturnal reef safe fish I can add to my 55 gallon tank. I currently have a yellow eye kole tang, a sand sifting goby and 2 peppermint shrimp.

Spotted cardinals are easy to keep, several will fit your tank, and they are nocturnal

Will they eat peppermint shrimp?

Will they eat peppermint shrimp?

MOST LIKELY SQUIRREL FISH are a good choice they like overhangs during the day

Most Squirrel fish in the trade grow rather large (7 -12" depending on species) for a 55g and they will eat anything that fits in their mouth - fish, shrimp, etc.
