Whats a good survival rate for CRS Babies?


By that I mean, per mother, how many shrimp typically make it to adulthood from a batch of eggs? Obviously factors will vary so hence looking for an average for comparison, I've got mostly A and S grade.

I started with 10 'teenage' CRS in early August, 3 berried around on mid/late September, and ~4 weeks ago they hatched. The juveniles are finally congregating and big enough to count in groups - counted at least 24 tonight, I'm guessing more are hiding in the plants.



Anyway just trying to gauge how I'm doing - I'm a noob to planted tanks and shrimp and jumped into the deep end but don't feel I'm drowning yet thanks to all the info that on this site.

10 Diamond head neon tetras
6 Rasbora Epeis
2 Ottos
9 adult CRS (one of the original crawled out )

Your shrimplets will be tasty snacks for your fish!

Doh! Hope not all of them. They mostly hide out in the plants though I do spot for them crawling on the HC in plain site of the fish and haven't witnessed any assasinations yet.

Sounds like you want to know more what a good clutch size is?

A good survival rate is +90%, a good clutch size is 20-30 depending on how large the mother is.

Sounds like you're doing just fine! Your fish will predate on some of your shrimplets, but I think with that thick HC mat, the shrimplets will have a good spot to hide and most should make it to adult hood. The main concern is once those fish figure out that those little red and white things crawling on the floor are very tasty, they will begin to harass the adults and you'll find missing eyeballs and missing limbs. Once that happens, you cannot untrain the fish, and your shrimp may hide a lot more.

Would be better if there weren't any fish. Great looking tank!

if you want, you could get one of those hang on back breeding boxes and if you see a berried shrimp put it in there with maybe a little bit of moss until the fry are a reasonable size.
heres a video link to an unboxing/ tutorial type thing of one. http://www.youtube.com/watch?v=Fnbg3...9xkLk2J5GK3W8A

I've watched my Neon and cardinal Tetras Dive into a Giant clump of Moss head first to get at a shrimplet so a DHG carpet isn't much of a hiding spot. Once they figure out they are tasty treats they hunt the shrimplets mercilessly.
they generally leave larger shrimp alone, although I have seen them pick at a poor shrimp that decided to molt in the open.
