This study investigates the reproductive quality of the freshwater angelfish,
Pterophyllum scalare, when using different feed type. Three replicates are used for
the two different feeds, pellets and bloodworm. The fish are feed for 2 weeks with a
screen present in the aquarium to separate the male from the female and prevent
mating. The screen is then removed to allow spawning to occur. The spawning
frequency, fecundity, fertilization and hatching rate are used to determine
reproductive quality. For spawning frequency only 1 of 3 for pellet while spawning
occurred in all tanks fed with bloodworm. Bloodworm fed fish also had significantly
higher fecundity and fertilization rate compared to pellet fed fish. However, eggs of
bloodworm fed fish failed to hatch, while the one instance of spawning in pellet fed
fish hatched normally. In conclusion, our study showed that we unable to conclusively
determine if pellets or bloodworm better.
