We suggest that male–male competition for mating opportunities may play a more important role in the guppy mating system than previously thought.doi:10.1111/j.1439-0310.2006.01142.xAnna C. PriceF. Helen RoddJohn Wiley & Sons, Ltd.Ethology...
The transparent tank (made of acrylic plate, 15×30 cm) was divided by an opaque partition (5×15 cm; height×length) into two separate containers (15×15 cm) for blocking the transmission of chemical and vibratory signals through the water between the two parts (each part was filled with...
When the pump was off, the swim tunnel was effectively sealed, and the measures of oxygen content within the tank could be used to calculate the oxygen consumption of the fish swimming within the tunnel. After placement into the tun- nel and the brief orientation session, ...
New adults were collected from the breeding tank within a day of emergence by check- ing the container daily. Since adult G. bimaculatus males need 4 days to become sexually active (Simmons 1986), this procedure ensured that all experimental individuals were vir- gins. Adults were ...
At the beginning of the assay, a male was gently transferred from the holding tank to the closed starting refuge in the arena. The subject was allowed to acclimate for 5 min, and then the trapdoor of the refuge was remotely opened and was not closed until the end of the trial. Following...

Each pair was placed in a 3-l tank for 1 week. The male was then removed, while the female was allowed to produce one to two clutches. Fry were removed from their mothers' tanks on the day of birth; we kept five to ten fry per mother (to obtain B10 fry per male) to establish ...
Male angelfish are typically less aggressive than females and you provided the tank size is proper, you should be able to keep a few in the same tank. ©Saad315/Shutterstock.com Males are considered less aggressive than females and typically do really well together in a tank. If you aren...
