Info
Serranus heterurus, (Cadenat, 1937)
Shrimp/small fish in the aquarium?
Due to the natural hunting instinct, shrimp or even small fish are considered food and, if the size is suitable, are also hunted and eaten.
Even cleaner shrimp can fall victim to the hunter if the hunger is correspondingly large.
Sex and mating
This species is a simultaneous hermaphrodite, meaning that the fish has both male and female gonads. If two fish are placed together, there will be no stress regarding gender. However, adding a second fish at a later date may lead to territorial disputes. Different sizes can also be a solution here (a larger fish is added later).
Distribution
Eastern Atlantic: West Africa.
Synonymised taxa:
Paracentropristis heterurus Cadenat, 1937
