In conclusion, fluoxetine exposure was found to generate effects on multiple levels, from overall boldness to consistency, when the behavior of male Siamese fighting fish was assessed in three different assays. Although for some measures the higher dose of fluoxetine appeared to have a greater effect than the lower dose, this was not always the case, stressing the importance of examining the consequences of PPCP exposure on multiple measures and in multiple contexts. For example, a dose effect on overall level of boldness was only found in the empty tank assay, whereas both doses generated similar decreases in behavior in the novel environment and shoal assays. Perhaps most importantly and alarmingly, the effects of exposure lasted even after fluoxetine was removed, although it should be noted that males were only returned to clean water for 1 week. This demonstrates that even short-term exposure to small doses of fluoxetine may have severe consequences as changes in activity levels and exploratory behavior may impact survival. As such, even brief periods of exposure could potentially produce chronic effects, especially as boldness is important in migration, aggression and predator evasion. For example, population-wide reductions in boldness may lead to fewer individuals searching for food sources or less aggressive males that no longer form and defend territories. Finally, this study suggests that serotonin may play an important role in generating or maintaining behavioral syndromes because fluoxetine exerts its effects via the serotonergic pathways. The mechanisms behind how fluoxetine alters boldness as well as studies on the more chronic effects of this SSRI and other PPCPs should be examined in the future.

Siamese Fighting Fish - Blue/White Elephant Ear Butterfly male Betta Splendens

The Siamese fighting fish mate in a fashion that is called "nuptial embrace", in which the male and female spiral around each other, around 10-41 eggs are released and fertilized at each embrace, until the female is exhausted of eggs. The male carefully keeps every egg in his bubble nest, making sure none fall to the ground, and repairing the bubble nest as needed. Incubation last 30-40 hours, and the eggs hatch in 3-4 days.

Red Siamese Fighter £4.95 - passive fish but only one male fighter fish per tank, or they fight to the death The Siamese fighting fish (), also sometimes colloquially known as the betta, is a species in the family which is popular as an fish. Bettas can be territorial fish and are prone to high levels of aggression towards each other. Two males in close proximity will almost always attack each other, if they do not have the ability to escape this will usually result in the death of one or both of the fish. Female bettas can also become territorial towards each other if they are housed in too small an aquarium. It is typically not recommended to keep male and female bettas together, except temporarily for breeding purposes which should always be undertaken with caution.

We found the strongest effect of audience presence when the audience is male. Males were most aggressive toward their opponent in the presence of a male audience when neither or only one male had a nest. This result is in general agreement with that of who showed increased biting frequency and decreased latency to bite in the presence of a male audience relative to female or no audience, but contrary to who showed no effect of male audience. Proximity to the male audience appears to have a substantial influence on the aggressive behavior of the contestants. In our study, the male audience was placed at an intermediate distance (9 cm) relative to previous studies (: 12.5 cm; : 7 cm). As the distance between two interacting male Siamese fighting fish increases the interactants become less responsive (), which may account for different responses to the male audience in the two studies. Thus, there appears to be a threshold distance (>9 cm) above which contestants fail to respond to the male audience. Although very little is known about the spacing of male Betta territories in nature, this threshold distance could reflect nearest-neighbor distances or a zone of increased nest defense.
