BN and shrimp

I have recently removed my very large albino foursome 2m 2f into their own tank, leaving behind my longfins.

In recent months I had noticed my shrimp population had not been growing as it was in previous years.

Since removing the large albino bn, I have noticed a huge increase in the number of shrimp.

I moved some of my larger rcs shrimp into the new tank with the large albino. Every time I looked their was berried rcs females in the albino tank. After my water change today I had a good look and I could not see a single rcs baby. They have been in there some weeks.

I would not have believed it if I had not seen this myself but it does appear to me that my large bn have been actively feeding on the shrimp. I have not noticed them eating them but the results are obvious.

They probably eat eggs. Shrimps just toss them around

is there a safe spot for the berried females to drop their babies? moss or similar?

In the main tank the java moss is huge close to 50 cm ball by 50cm heaps of anubias, but there is a severe river snail problem.

In the new tank I have gone to extreme lengths to avoid a similar snail problem. there is ample drift wood a small anubias plant and the moss is meagre to say the least.

There should be hundreds of shrimplets by now there is not one.

I never considered that they could be devoured as eggs  

I must admit that i have never had this problem before. I have had bristlenose and shrimp living happily for years. What are you water paramters, particualrly KH and GH?

i have 2 BN's in my shrimp tank with no problems at all
water paramters may be off

I don't think its the parameters, since removing the large albino from the main tank I have seen a massive increase in the shrimp population compared to when they where in that tank.

I specifically chose some of the largest, darkest cherries to move into the new tank, I will be collecting them and putting them back in the original tank until the java becomes more substantial.

Regarding the eggs I have been told that the shrimp release live shrimp not eggs so if they are eating them they are eating shrimplets not eggs.

The largest of the albino males is around 15 cm in my mind I think he has developed a taste for shrimplets.

yes they release shrimplets

Just info sharing,

Seems I have erred in my assumptions again,

The tank housing my large albino's is steadily filling with rcs. ???
