General Care of Angelfish
The actual aquarium size is relatively unimportant. However, the
number of angelfish per gallon is critical. This figure varies depending
on several factors. Obviously, size has a lot to do with carrying
capacity. Other variables that affect this include, pH, temperature,
feeding practices, water changing volume, water changing frequency,
strain of angelfish being kept and the overall quality of angelfish
you desire to raise or maintain. Keep in mind, the number of angelfish
per gallon a tank can handle, will vary immensely from one situation
to another. The following would be a very general guideline.
|Nickel size bodies
||1 angelfish per gallon
|Quarter size bodies
||1 angelfish per 2 gallons
|Silver dollar size bodies
||1 angelfish per 3 gallons
|Stock ready to be paired
||1 angelfish per 5 gallons
|Full grown breeding pair
||20 gallon tall
Good biological filtration
be easily obtained a number of ways. Angelfish body shapes are not
designed for efficient swimming, therefore gentle aquarium filtration
is preferred. Lots of water movement will stress them somewhat and
cause slower growth due to the increased energy expended to swim
against a current. Angels Plus Sponge
are ideal for fish hatchery situations, where expense
is a concern. In show tanks, undergravel filters works well. In
a densely populated tank, a whole-tank filter
a very effective option. A very effective secondary filter
that will not clog is a fluidized bed filter. In general, the limiting
factor for angelfish carrying capacity is not biological filtration. It is
dissolved organics and high bacterial loads that develop from keeping
too many fish in a tank, overfeeding or changing too little water.
Large, frequent water changes are the easiest way to lower these
dissolved organic and bacterial levels. Sophisticated systems will sometimes incorporate
the use of ozone, foam fractionation and U.V.
to accomplish the
lowering of these organic and bacterial loads, but most of us will
rely upon water changes to accomplish this important facet of angelfish
Angelfish have a tolerance to a wide range of aquarium temperatures,
but immune system response is best at higher temperatures. Therefore,
if your fish husbandry is less than ideal, you will have more problems
at lower temperatures. 80° F is a good start for a hatchery situation.
Mid to upper seventies is fine for show tanks.
As a cold blooded animal, angelfish will live longer at lower
temps. Higher temperatures will promote faster growth, more frequent
breeding, better immune system response and shorter life spans.
Feeding is more of an art, than a science. No one can tell you exactly
how much food to put in an aquarium. The ideal amount will change
everyday as the angelfish grow, and will be different with varying
temperature, pH, maintenance schedules and frequency of feedings.
Good observation is the key. Overfeeding angelfish is worse than
underfeeding. Feed a variety of high quality
and observe the aquarium and the angelfish closely when
feeding. If you want to feed a superior fish food, try making your
own paste fish food
. We have
a great fish paste food recipe.
Angelfish Fry - For the first 3 weeks of their life you will find it difficult to raise any number
of high quality angelfish with anything other than live foods
live baby brine shrimp or
microworms. We feed
these exclusively for the first
4-5 weeks. Check this link for more details on
brine shrimp eggs. Introduction of a new fish food usually requires
that it be introduced gradually. Angelfish should be voracious eaters
when they are healthy and properly fed.
