Project "Dither Shrimps"



Cherry Shrimps
Genus: Neocaridina
PH: 6.5 to 8
Temp: 18 to 30 degrees

Sulawesi Shrimps
Genus: Caridina
PH: 7.5 to 8+
Temp: 26to 30 degrees

Definition of Dither Project:
14 male adults and young Cherry shrimps added to an aquarium with shy or nervous Sulawesi shrimps. The dither shrimps' unconcerned behaviour signals to the shy shrimps that it is safe to come out of hiding, to feed and it is safe to breed.

Cherry shrimps are chosen as dither, since they are hardy, and can tolerate the temperate range and PH range of the Sulawesi setup. They are also not shy, and going around the tank looking for food all the time, with or without people staring at them.

Sulawesi Shrimps in my tank, including Cardinals, Yellow Stripes and Yellow cheek are a very shy species. They basically like to come out only when the lights are off. Sometimes they do come out in the day, but would quickly withdraw back to their crevices when they sense people, sound or movement.

Period of Experiment:
1 day and ongoing

Day 1 Observations:
Cherry shrimps are adjusting well to their environment. Initially, they were swimming around the tank, checking out the environment. After awhile, they started picking on the food and algaes found in the tank. No aggression between the cherries and sulawesies in the day.

Sulawesi shrimps became more curious when the cherry shrimps were introduced. They stepped out of their crevices to check out the new inhibitants.

After 3 hours, Cardinals shrimps were seen perched on top of rocks, and busy grazing on algae with their claws or white chelipeds. The yellow cheek and yellow stripes were not seen. This is the first day, and they could be resting from the previous night's foraging.
