How many make sense

[eDavid]

I'm going to be populating a new 125 gallon 6ft long tank soon, and trying to figure out a couple showcase fish that can fit with peaceful community fish.

From what i've read, 1 would do. In a tank this size would 2 work, or would they fight. What number would make sense, or just the one? I find so much conflicting information it's tough to find some authority. THanks

Two would befine i think ifyou got a nice mated pair (they get jerky durring spawing so carful) or 2 nice females and its a pretty planted tank i have a pair in my 75 right now with no problems but i know they can be real jerks so i'll let someone else that has kept them long then me chime in

With 125 gallon and if it was heavily planted, you should be able to have a few angels. Larger groups in large aquariums work where in smaller tanks if you haven't a pair then it's best to just have one due to their aggression.

The factor will be environment and husbandry.

Environment being that in the wilds angelfish occupy water ways that become heavily planted with leafy plants and other items such as roots and wood during spawning time.
In an aquarium we seldom plant our tanks as nature creates her space, we under plant the area. In a properly created environment for angels the area would have visual blockages that keep the fish partitioned naturally from each others view. Out of sight out of mind. Properly partitioned and planted a 125 could ideally house two mated pairs if the tank is planted correctly and the field of vision is blocked to segregate the pairs. There would be some interaction but it could be limited by the plantings and a true territory established for each pair if you have good husbandry techniques.
Visually this may not be what you would want to do. As a plant keeper it would be a lot of work.
You can also select only females to have a larger display of angels. There would be some pecking as the females will still lay eggs in female mock pair bonds but it will be minimal.
It can also depend heavily upon the fish and it's genetic back ground. Some types are more docile than others naturally.
There can be a lot to this keeping of angels, they are a rather socially complicated fish. It can take a bit to get a read on them. I have several 120's with 8 adult angels, having several I can rotate out toughs to other tanks and pair diminutive types to each other. I am studying this a bit so as to see if aggression can actually be relieved from the species through selective breeding with out ruining the essence of the fish.
