Thre gigantic altum angel is one of the most sought-after fish but it, not one an animal recommended for beginners or even the average aquarist.
Even advanced fishkeepers find the altum to be challenging.
However, a group of them can be advantageous and truly beautiful.
Tank Setup & tank mates:
While the ordinary Altum angels are very adaptable in regards to water chemistry, water quality, and tankmates, the altum is not.
It has some extraordinary needs that must be met, starting with the depth of the tank. Altums can be very tall.
There have been individual fish whose fin height measured at 38cm tall /15 inches. For the fish not to drag its fins, they need a deep tank of at least 55 gallons/ 200 liters.
all Altum angels fishes are caught from the wild, which is why they are not seen in stores very frequently.
Because of this, the water chemistry in their tank must match what is in the wild. The pH of the container must be between 5.0 and 6.5.
They will not survive long in water with a higher pH than 6.5 for long and breeding, as difficult as that is, will only be possible in the pH at the lowest end of that range. Tankmates can be problematic too.
Altums have larger mouths than other angelfish..a fact they frequently show off by “yawning”… and can easily swallow whole the tetras that would otherwise thrive in low pH waters. Some corydoras are fine, but be sure to select only ones that like very high temperatures.
Some people suggest keeping them with discus, which is possible except when the latter are spawning. The Altum angels will overpower the discus parents to eat their eggs.
Because the majority of the fish come from the wild, they may have internal parasites. You should treat for that being sure that the medicine you use contains no copper. Copper proves lethal to them.
They may also have an external parasite called “Black Spot Disease” on their body and fins. Do not be alarmed.
That is an internal parasite of birds that the bird gets by eating the fish. It is harmless to you or your angelfish and will eventually disappear on its own.
You might be wondering:
Why a fish that is so difficult to raise and accommodate is so popular?
You only have to look at some videos on “Altum angels” to see the answer.
They are majestic and stunning beauties when happy in their environment.
Origin: Columbia and Venezuela
Size: Length: 18cm/7″; height: to 38cm possible but usually around 25cm/10″
Temperature: 28-32°C/ 82-90°F
Feeding: Newly captured fish may eat only live food at first. They quickly adapt to frozen and will eventually take flakes as well.
Adding peat to the tank or inside the filter will help to lower the pH. It will also dim the lighting in the water which Altums prefer.
They also like heavily planted setups using floating plants and many tall, broad-leaved plants like Hygrophilia and Echinodorus.
The substrate should be sand or fine gravel. The angels sometimes dig or use their large mouths to pick things off the bottom.
Sharp rocks may cause injury.
use branches or driftwood that look like large tree roots simulate their natural habitat where overhanging tree branches often drop into the water.
Breeding: Altum Angelfish
Very difficult. They breed like other angels but are more likely to eat their spawn repeatedly.
Some breeders try to raise the eggs away from the parents, but the become Fung used efficiently, and the number of fries raised is usually quite small.
