Tropical Fish and Aquariums doesn't promote selling of Glass Fish injected
with fluorescent dyes. Click on the following graphics for more
information about campaigns against this process. The Glass Fish originated
from brackish waters in India and Thailand.
It is also known as the Indian Glassy Fish, Glass Perch, Disco Fish and the
Painted Glass Fish. It is known by the scientific names Parambassis ranga
and Parambassis baculis. It has a translucent clear glass appearance and
its internal bone structure is clearly visible. The body shape is similar to
that of a Blackskirt
Tetra. Both of these species are unfortunately
subjected to dyeing, as discussed below.
The Glass Fish should be kept in
groups of 4 or more in large aquariums with heavy vegetation and rocks.
They are active and also require open swimming space. The Glass Fish can
be fed flake foods, but prefers live foods. It will eat brine shrimp,
wingless fruit flies, bloodworms, glass worms and tubifex worms. The Glass
Fish is difficult to breed. Eggs are laid in nests that it builds or among
plants. Several hundred eggs can be laid and the young are guarded.
The Glass Fish is frequently injected with various fluorescent dyes using a
large gauge needle. In fact, “unpainted” varieties are rarely
available. The injections kill a large portion of the fish that are
initially injected. Others develop infections while the dye is lodged in
their cells. The small percentage of fish that survive will lose most of
their coloration within 6 months. The practice of painting these fish has nearly
eliminated the availability of the unpainted variety in the pet industry. For

Tetra and the Blood
For a natural version of a glass fish, try a Glass Bloodfin
(Prionobrama filigera). This tetra has a glassy body with a red tail fin.
