Gramma brasiliensis, Sazima, Gasparini & Moura, 1998
The photograph by Hiroyuki Tanaka shows the Brazilian fairy bass.
It can hardly be distinguished from the gramma loreto by the layman, although the eye line is missing on the brasiliensis.
Mostly, however, Gramma loreto is sold.
Both fish are easy to keep and can even be kept in groups of about 4.
However, one should not take an uneven number, as they usually form pairs.
Easily accept replacement food in the aquarium.
Replacement behaviour.
Relocating fairy perch should be done carefully, the fish tend to go into shock in the transport bag or after relocation, although this quickly resolves.
Sex and mating
In addition, the sex of this species is determined after hatching and cannot be changed (gonochoric), at least once they reach a certain size/age. The sex develops during spawning and is determined by the water temperature.
The male fish is larger than the female. Subsequent mating may be successful, but this is not guaranteed. Unfortunately, there is no scientific evidence on this yet. Perhaps subsequent mating is successful if the replacement fish are still very small.
If you have any personal experience or scientific reports on this, we would be very grateful for any information.
