The aquatic world is filled with boundless species that enthrall the human mind. One of such is the angelfish, which is a type of ray-finned fish.
With so many species attributed to the saltwater angelfish, they can be classified into two groups. There are the Marine and Freshwater angelfish, which all have unique body-color patterns.
Thanks to their unusual shape and beautiful body colors, both freshwater and marine angelfish are very popular fishes for reef tanks, but not all angelfish are reef safe fish.
This is because they tend to pick on noxious soft corals, especially in the absence of live rock, causing the corals to die.
However, below are the 13 best reef safe angelfish for your saltwater reef tank.
Interesting Facts About Angelfish:
Most popular dwarf angelfish can reach 2 to 24 inches in length, depending on the species. They are mostly omnivorous, and they eat algae and even corals. This one-of-a-kind fish is a brilliant creature that can recognize its owners.
This is due to their optic lobes, and it has even been proven that some saltwater angelfish species can recognize their reef tank mates. It is also challenging to differentiate between males and females because they are equal in size and have the same color.
Reef Safe Angelfish – Dwarf Species
Even as adults, the Dwarf Angelfish species seldom grows greater than 5 inches in length.
