to tend to a large number of fry, it’s necessary
to remove the fry before they swarm all over
the one parent, eating and tearing into the
sides of it.
Surprisingly, young discus are able to
accept newly hatched Artemia (brine
shrimp), and I’ve always found that they
can find and eat these after four to five days.
We use 20-gallon tanks for the spawning
discus pairs, and we attempt to remove
their fry to other quarters as soon as we see
them accepting the newly hatched Artemia.
When the young discus do accept the offered
Artemia, they will still be eating from the
parents, and will be growing rapidly.
The swarm of fry feeding off this parent will soon switch to the other parent; in absence of a second
parent to provide slime-coat feedings to a large number of fry, it’s best to remove the fry before
they do damage to the single parent.
settle down and successfully raise their spawn.
And in many cases, one might find that either
the male fish or the female fish will not be a
good parent, and will eat the eggs or the fry. In
If the discus fry are removed from the parent
20-gallon tank, it’s not a good idea to put them
in a tank much larger than the parent tank. In
one too large for the discus fry, they may easily
be found wandering around and not settling
down to find their food. Ours usually find
themselves in 15-gallon tanks, and with proper
filtration and large water changes, the fry
grow rapidly. For any maximum fry growth,
we find that daily water changes of at least 40
percent are necessary. And with good quality
water—and time—why not make even larger
water changes? D
cases like that, the other parent fish—the one
that guards the spawning successfully—can
very easily take care of both the eggs and the
young discus. However, if only one adult is left
