want to share some experience i have gathered with CRS in the past year.
last march i got 15 young CRS from a friend.
they were about 1cm big and came in different grades.
they grew up nicely and steady, with good coloration.
i feed them tetra bits and sera shrimp food 3 x weekly, however they do not really like shrimp king pellets
FTS: 50l, 37W PLL, no CO2, no ferts, no glut, substrate: sand
after 5 months i did one of the weekly water changes and lost 12 of them...i suppose it was high chlorine due to the rainy season.
three survived, but lost a lot of their colour.
i was lucky to get 7 new young shrimps from the same blood line in october.
beginning of december the adult ones started to swim like crazy in the tank, and 2-3 weeks later:
female carrying eggs (this is one of survivors which lost a lot of colour in july)
beginning of january i found the first shrimplets
size difference
they seem to be established and grow nicely.
learnings:
- CRS are sensitive pansies, unlike RCS
- they need a matured tank
- some breeders strongly advised me not to change the tank setup while keeping CRS in it...any change will disturb the micro flora&fauna and might cause losses of CRS
- weekly water changes...the shrimps need minerals, which only a water change (or lavish use of certain, costly salt) can provide.
- do not mix bloodlines (as a beginner): i had the possibility to get some more CRS from another blood line, but i was advised by some breeders not to mix both blood lines, because both carry different bacteria and are not used to the bacteria of the other blood line...losses among the CRS are likely.
- seed shrimps do not harm directly the CRS, but in large numbers they annoy the CRS by their sheer presence...and are food competitors to the shrimplets...but i have no idea how to get rid of them without loosing some shrimplets
suggestions and advices are welcome
