First CRS babies

I got home after work yesterday and found two surprises. One was that my Golden Apple snails laid some egges on the tank wall above water where I laid a piece of glass on top, counted about 20-30 eggs.

Secondly, I got some CRS from Ricky on March 29 and found  one berried female two days later. I thought it should be any day now and I was so happy to find one CRS baby (I was looking for one). Didn't have time to try to find more because I had a church small group meeting in the evening. Came home fro church and I could see 4 to 5 in sight, I're sure there are more as even they are right in front of me I can hardly see them if they don't move.

Baby CRS are very different from baby Neos in that they hatched as small miniature CRS with colour, where as Neo babies hatched colourless and won't develop any colour until 10 to 14 days old, and colouration gradually develops.

Anyway... so happy Thanks God for these baby shrimps. There are 3 or 4 berried females in the tank and one or two of them should release in the next few days.

Random facts in water parameters (updated 2012/04/17)

General:
- 0.1ppm of NO2 is considered the limit for aquatic animal safety.
- 0.2ppm of NH3 is considered the limit for aquatic animal safety.

Shrimping Conclusion : 

- NO2 and NH3 should always be 0.


NO2-
- NO2 toxin isn't affected by temperature, and isn't affected much by PH. (4)
- But some says the the toxin of NO2 isn't affected much by temperature in basic water only. (3)
- NO2 toxin reduces as GH increases. (4)
- NO2 is more toxic when dissolved oxygen is lower (NO2 affects oxygen carrying, lower DO in higher temperature)
- NO2 is slightly acidic, in low PH it more easily formed.
Shrimping Conclusion : not much we can do other than make sure bacteria is establish to convert NO2- to NO3-.


 NH3:
- NH3 is more toxic when temperature or PH is higher

Shrimping Conclusion: 

- Be alerted when it gets too warm, NH3 can be a bigger issue.

- Lower PH to minimize NH3 toxin (NH3 -> NH4)


PH:
- Low PH affects oxygen carrying ability. (Shrimps need more DO to compensate low PH).
- High PH affects gill ability and can cause problem.

Shrimpping Conclusion:

- Make sure water is well aerated  in low PH tank.

PFR

One of my PFRs, I have to say I have better ones but this gal came to the front of the tank for a photo op while all others hid in the back. Not having a macro lens really limits what I can do with the photos.

Breeding frenzy

The CRS I got from Ricky have been in breeding frenzy. I count 4 berried today and male shrimps are still flying. May (and hope to) see more berried mama tomorrow. I got these from Ricky on March 29, one got berried the day after. So by end of April I should see some babies.

And see the males going crazy looking for newly molted females.

First OEBT

My first OEBT, I got 11 of these plus 10 mischling. One of the mischling looks like a panda. But it's still small to tell. I got these on April 11, 2012.

For my short term memory ...

I don't want to keep looking up these terms. Will keep updating, let me know if you find something that should be added here.
