Younger bees are more hardy?

[NanoDave]

I recently bought a few bee shrimps in different sizes. As I bought them cheap (like 50cents) and as I was in a rush I did a very quick acclimatisation before they all go into the tank. The next day all the big ones died leaving only small ones (but not shrimplets, they are just younger). I thought they are going to die soon but to my surprise they are very much alive even now.

Any thoughts on this phenomena?

(btw its not something wrong with the water the tank is well cycled and there is zero ammonia and nitrites plus I do water change and there are cherrys and crs in there too)

NanoDave,
Generally Bee shrimps are very sensitive to water changes.

A slight difference in PH e.g. 0.5 increase could wipe out your whole Bee shrimp population, the lack of acclimatization in this case has tested their limits. All most young(1month old and above) are more adaptable to changes in the water parameters but i reckon when they grow older they will lose that adaptability.


Just curious, has any one managed to breed them?

I have a friend who can breed them in singapore. He told me it is quite easy, just need chiller will do. Because these are cheap shrimp, nobody want to spend the money to buy chiller, they just buy hoping they could survive our singapore climate. In the end, the bee population decreases day by day and lastly, they give up on these shrimps.

So did your friend use chiller? The population increase or decrease?

My friend use chiller, that why he can breed bees. His poplution increase from 20 to about 100 now.
