Tiger Breeding - what happened to my eggs?

[kingborris]

I have a 3-gallon planted shrimp tank with sand substrate and small internal power filter (running slowly).

In this, I have Tiger and Cherry Shrimps (half a dozen of each) and Malaysian trumpet snails.

I noticed a couple of my tigers were carrying eggs a while back. About a week and a half ago, I noticed that they were no longer carrying these eggs - however I am yet to see any shrimplets. Where could they have gone? :huh: Have they all died? Could they be in my filter although the turnover for this is very low. Or are they just hiding out in the forest of plants in my tank (mainly Heteranthra zosterfolia).

Any ideas welcome. Thanks. :D

How long did the tigers carry the eggs? The gestation period is roughly 3 weeks. If they were seen w/o eggs before this time has passed, it is likely that the eggs were dropped. If the eggs hatched after the 3 week period, you should be able to spot the babies, unless the foliage is very dense.

What are your water parameters?

Hiding in the "forest" could be a reason.
Little Tigers are not so good to see like baby bees or CRS and they´re not swimming around like Babaulti Green shrimplets for example.

Although the filter is running slow the shrimplets can get into it.

Water parameters are GH, KH about 6 to 8, pH 7.6, NH3 NO2 NO3 are zero.

Good news re shrimp. I definitely saw two tiger shrimplets by the back of the aquarium although they are very tiny! I am presuming there are more shrimps hiding in my plants.

Any ideas on approximately how many shrimplets are born per shrimp?

Hi,
a normal healthy tiger shrimp female should give you 20-35 shrimplets, depending on her age. I would say that 25 shrimplets are a good result.

A survival rate of 50% is a good result.

here's one of the shrimplets (which is badly out of focus) resting on a leaf o regular vallis :)

Good job! Congrats!
