Petshrimp.com Discussion Forum

I have noticed for some time that some of my RCS pregnant females (the ones with yellow patches) have a thin crack near their head connecting to their bodies. I have seen one post earlier in this forum at viewtopic.phpt=93&highlight=feeding
and there was a picture posted by someone at the bottom of this message.

My shrimps do not have that wide of a crack but close to it.
I would like to ask if anyone knows why that happens? My RCS females all have very nice deep color yellow patches around their neck which I know are ovaries. However, I have kept the shrimps since April and I still haven't seen any eggs yet. I have only seen it once in one female RCS and it dropped her eggs around one day later. I have already removed all of my Amano shrimps, and one golden beard algae eating fish close to a month now. I change my water (20-30%) once every two weeks. My kH is around 5 now and my gH is around 8. pH is around 7.2 and temp. is around 77 F, ammonia, nitrite, nitrate is 0 in a 20G L planted tank with a CO2 injector. Any help would be really appreciated. Thank you.

Do you have something that regulates the co2?

I've had bad experiences with diy yeast injectors. Plants did great. Shrimp did horrible.

Yes, I have a JBJ CO2 solenoid regulator. It only pumps out CO2 one bubble every 2 seconds. I hope that is not the case.

That has happened to one of my best cherry female. I thought something attacked her from behind (a very horny male, who just didn't know where to stick it!!!). She stayed alive for 2-3 days and perished. When I removed her, her head plopped off her body. IMO, I think it was an internal parasite that got to her. Just a guess, not a definite answer. I pray to GOD, to keep my shrimpies happy and healthy. That reminds me, I gotta clean out the tank. Maybe some here has also had this problem too.
