大部份的卵子已經散下(在網袋內), 有六七隻2mm度的幼苗在游泳.

b5,

I saw an article saying that the eggs take between 36-48hrs to hatch.

The description from another article also very similar to my case:

I've the same experience many times as b5 case, however, I could not keep any of the babies.

Gundaman, you are trying to keep the baby shrimps, right? Hope you can succeed.

隨緣啦.

My pregnant shrimp was placed in a breeding net. Will the shrimp eat back the 幼苗/eggs?

pmchan,

I just knew little about breeding, mainly from the previously-menitoned web page. But I can still afford to share something with you.

My procedures are as follow:

1. Place the pregnant shrimp in a breeding net (mine one was got at Rivulet for $15, don't use those for breeding fishes, as recommended by the shopkeeper) in your main tank;
2. Continue feeding the shrimp directly by your hand/tool - I feed it with dry food/krill;
3. Observe the color of the eggs - details can be found at previously-menitoned web page;
3. One day it doesn't accept any food - a sign to 散下卵子 - I think it occurs at night/dark room;
4. 孵出幼苗 in 36-48 hours - difference maybe occur;
5. ...............................(I know nothing yet.

)

BUT I will siphon out the eggs/幼苗 in a separate plastic box with an air pump tonight. Also, I think feeding them with anamone food (those food for filter-feeder) is enough, becuase 幼苗 are only able to eat by filtering water.

Hope this help.

Can you see those 幼苗?

You are right, b5, 原來D幼苗已經全部在一晚內孵出, 只是大部份藏了在網底.

估計有百多隻.

Over 80% is alive.

------------------------------

Here's the schedule for my reference (and your reference):

History: 2.5" pregnant doctor shrimp was purchased on 30 May. It was already came with "green-eggs". It lived with boxing shrimp and other tankmates (including doctor shrimps) in a tank without any separation - but not that pacefully with boxing shrimp;

02 June:

I separated the pregnant doctor shrimp into a breeding net at midnight;

03 June:

The larvaes were being found on the breeding net's base. (The larvaes were hatched most likely at between midnight, 02 June and morning, 03 June);

By using a siphoning device from Hagen's test kit, I siphoned all the larvaes into a plastic cylinder with tank's water and an air pump (air output=min.) to avoid eating back of the larvaes by the adult doctor shrimp.

Continue......

剛剛生產完的醫生蝦 - 等佢再換殼後才放回缸中(simply for 等佢D天線生番完整先, 並冇乜特別要求話要換殼後才可放回缸中的), 而家佢都只是食少少野:

D幼苗實在太細(1-2mm長)(大部份在箱底), 我部DC又只是入門級機種, 很難拍到一幅較清晰的相片給你們看.

睇住呢幅先啦!!! 等我唸下有乜方法先.
