Yamato compatible with CRS?

**tflow** · 14th Jan 2010, 14:28

Hi guys,

Any advice on whether yamato shrimp are compatible with CRS in a 2ft tank, with quite sufficient hiding space.

Will it be harmful, especially to shrimplets?

Thanks for any advice.

It depends on individual . I see yamanto are quite aggressive when they get really huge .I have seen in another forum a yamanto taking down a crs. Its up to u though

I have bought 10 yamatos several years ago... most are still around and 3-4 have grown big and thick
they like to bully other shrimps, as in they will snatch the food like hungry ghosts but I have not seen them attacking and eating my other smaller shrimps (cherry, malayan, tiger, hybrid).
even my CPOs are not spared... the big bullies often challenge my CPOs for the food pallets

I have 2 yamatos in a one footer with sakuras, and my sakuras are breeding with increasing numbers. So think should be compatible with CRS.

My advice is don't try. I've had bad experiences with Yamatos with Cherry shrimp.

Bully the smaller shrimp, steal their food, kill my snails. I never saw them killing my cherries, but they did bully and stress them out all the time, and even more at feeding times.

I see thanks for all the advices. I am concern as i have some in my tank, and their sizes is at least 2-3 time bigger then my crs....

Think will try to remove them just in case.

If CRS is your priority, take out the yamato. Why you need them anyway.

**tflow** · 15th Jan 2010, 10:26

Yup CRS is my priority.
I place in the yamato during the initial stage to test water, as well as helping in algae bloom issue.

Thanks, will remove them soon

that is also what i did initially for yamato to test water condition and remove it later before introduce CRS

Bigger size & larger quantity usually has upper hand when come for feeding. If you put more food for them, yamoto will grab its share and hide somewhere to nibble without bothering other smaller shrimps.

My 2nd generations of snowball and sukura have grown up healthily with the presence of 4 Yamotos in my 1foot tank. My baby CBS has now grown to almost 3/4 the size of my sukura now. My low grade CRS was not afraid of my yamoto and I even saw one CRS chasing yamoto for stealing its food. Under normal days without feeding, Yamoto and other smaller shrimps are very harmonious in a shrimp community tank. It is like pigeon and sparrow living together. Thus the pigeon will not harm the sparrow babies for sure with good nestings.

Yamoto has its beneficial function too. When food particles were burried inside the soil after some time, Yamoto has the strength to burrow deeper into the soil to seek trapped food particles which indirectly benefit smaller shrimps nearby.

On the other hand, my blue shrimps were more aggressive than sakura. They attack other shrimps by climbing over them and scratched their head - like the action of "boxing" during feeding. I was so scared that I give them away and now my tank got no more blue shrimps.

The verdict:
Always keep aggressive shrimps in smaller quantity or else they can become quite cocky.

Sorry for being so "Cheong Hei" because I want people to treat yamoto fairly just because they are less pretty and clumsy.
