The Butterfly Goodeid
Water Conditions- Not Critical. Temp 70- 78 Degrees,
Plants, Vegetable in Diet
Behavior- Generally well behaved, can sometimes
be aggressive with other, smaller fish.
Breeding- 5-15 Young every 60 Days. Females do not do
well when moved to spawn. Not Fry Eaters.
Size- 3.0 inches
Once sold in pet
stores, this is one of the hardiest and easy to keep goodeids.
Recently thought to be possibly
extinct in the wild, they are kept today by a few specialty
hobbyists, who understand that as well as being easy
to keep, they is also one of the most attractive. “Butterfly
Goodeid” does fit this beautiful fish, both sexes of
this line are distinctive for their high contrast, complex
markings, with males possessing an especially bright
yellow stripe down the tail.
When provided with conditions they like, and that suits the
survival of fry, they can be quite prolific and live
comfortably within a colony that will get along. Occasionally
a particularly large older male or female will bully
others, but it never results in deaths or fin nipping between
They are kept in bare-bottom 30 gallon tanks with potted
anubias, Java fern and bolbitis fern (see
Two large box filters provide filtration and aeration.
Moderate light complements places to hide, but without
mulm buildup on bottom.
Their only real issue is that the females do not do well when
moved to another aquarium to have their young.
When caught in a net, jostled etc. then put into another tank the
female will often either drop her fry within 24 hours,
dead, or simply die herself. If the female is small enough,
you can put her in a net breeder in her home tank,
particularly if you are swift with a net and provide a
minimum of disturbance. Fortunately, they are not big fry
eaters, and the young will do OK if they can get to food, and
aren’t eaten by another species in the tank.
When left to community breed in a 30 gallon tank with
moderate planting the population will tend to increase
fairly rapidly. This goodied is second only to the
Chapalichthys pardalis for being prolific.
They do well on a quality dry food, but require a vegetable
component in their diet, and benefit greatly from
occasional live food, particularly baby brine shrimp. They
also seem to eat the small algae eating neocaridina
shrimp , which most fish do not do. Though more tolerant of
warmer temperatures than some goodeids, they will
begin to die off and could become sterile when exposed to
temperatures above 77-78 degrees. Here they are kept
at 70 - 74 , where they have done very well.
