Good Grouping Species
Most Angelfishes live a solitary life, but some wander the reef in small groups of two or three, which are usually mated pairs or trios of one male and several females. It is not uncommon for multiple males and sometimes females placed in the same aquarium to fight, often to the death, and although many Angelfishes do best when kept singly, one to an aquarium, here are some species that can be kept together under the right conditions.
- Lemonpeel Angelfish (Centropyge flavissimus): Makes a good pair, and a trio of one male and two females can be kept in no less than a 100-gallon aquarium.
- Cherub Angelfish (Centropyge argi): Good for pairing and two or more females can be kept together, but only as long as the tank is at least 50 gallons in size and they are all added at the same time.
- Blackspot Angelfish (Genicanthus melanospilos): Can be kept in small groups in a larger aquarium, but with only one male present.
- Herald’s Angelfish (Centropye heraldi): Makes a good male-female pair but in a minimum 75-gallon aquarium.
- Bicolor Angelfish (Centropyge bicolor): Can be kept with other individuals, but only in a minimum 75-gallon aquarium and all are added simultaneously.
Aquarium Introduction Tips
Extreme dominate or territorial aggression occurs most often when an Angelfish has been established for some in an aquarium and a new tank mate is introduced. If you are going to add an Angel to your aquarium community, it is suggested, unless otherwise noted, that it be introduced into the tank last.
When decided to keep multiple Angelfishes in the same aquarium, it is best to choose mated pairs, species that commune well together or pick dissimilar species, and then introduce them into the tank all at the same time.
If you already have an established fish community and want to then add an Angelfish, you can try removing all the fish present in the aquarium and re-arrange the decor if possible, then place all the fish back into the tank along with the new Angelfish.
Other Key Factors For Success
By providing Angelfishes with ample room to move around and shelter to hide in it allows them to better keep away from other fishes, as well as establish a more spacious territory of their own. This all helps to lessen the effects of territorial disputes with other tank mates. Of course, as true with most all marine fishes, there are no guarantees that fights or conflicts of some kind won't occur, especially taking into consideration the aggressive nature of Angelfishes.
