Caridina sp. (update #2)

It has been almost 2 months since I received this species of shrimp from a member of one of the forums I participate in. After quite a bit of observation and a few comments from knowledgeable shrimp keepers I believe they are Malaya Shrimp (Caridina sp.).

I am not 100% positive of this identification because I have not had a berried female. The Malaya Shrimp has a short larval stage, and is the major factor I have not been able to test out yet!

I am afraid that I will not be able to test that theory out either. It looks like the one shrimp I thought could be a male is developing to be female:

It is hard to see, but it looks like there is a saddle beginning to form.

Well, I guess I will have to wait and see. If this shrimp turns out to be a female I am not sure what I am going to do with these shrimp. I don’t want to mix them with confirmed Malaya Shrimp because I am not sure that they are Malaya Shrimp.

I will update as soon as any progress is noted.

Soft Water Shrimp in Hard Water (update #3)

I have found another berried female in my soft water aquarium! That makes a total of 3 females that are now berried!

This female is the smallest of the 3, but it looks like she is carrying close to the same amount of eggs as the other females.

There are still no berried females in the hard water aquarium, and they seem to be just a little bit smaller (I have not taken them out to measure them!)

Soft Water Shrimp in Hard Water (Update #2)

First Results

I set up this experiment on June 20th and I have my first results.

My first female Tiger Shrimp have become berried! There are two berried females in the soft water aquarium.

The aquarium parameters are as follows:
Temp:  74.8
pH:       6.4
TDS:     112 ppm

These shrimp appear to be growing just a little bit faster than the shrimp in the hard water, but it seems to be by a slight margin. There is no sign of breeding activity in the hard water aquarium as of yet.

There have been no losses of Tiger Shrimp to this point.

One observation that was unexpected is in the soft water aquarium. One of the Tiger Shrimp has developed an interesting color pattern. Similar to the shrimp that are being called Red Tiger Shrimp.

A Few Random Pictures

I was messing around with my Nikon D40 today and took a couple pictures I though would be worth sharing.

First is a unique Ramshorn Snail that I have in one of my shrimp aquariums.

This is the only Ramshorn snail I have that looks like this! Unique!

Also here is another photo of some of my Caridina sp.

There are still no berried females in this aquarium, I am still waiting to see what happens!
