    Are Yamato/Amano shrimps cannibalistic?

    Curious because I just saw one of them munching on a dead shrimp (no idea what type because I have also cherry reds, tigers, blue tigers and oranges in my 2 ft planted shrimps-only tank. My other 2ft planted tank consists only cherry reds and fishes).

    Plus they are most often the quickest to appear to reach the food pellets or bulldozing their way through to reach the pellets or snatching from others the pellets.

    Read from one of the posts they do attack shrimps which had just molted with a soft shell...

    Any bros got any advice or similar experiences?

    Thanks.

    Hi,
    Yamatos are great algae munchers as well as scavengers (on dead organisms), however i don't think they are likely to attack any healthy and living fauna in the tank.

    Cheers!

    Well... sad to say they do attack and wipe out my cherries.

    If that is the case, I am curious then. Why are there other aquarists who managed to keep Yamato/Amano shrimps together with other dwarf shrimps, without such issues?

    could it be the size differences? because in my case the yamato was like twice the size of the sakura...

    i keep amanos with cherries and malayans in a community tank too. have not observed anything yet but have read elsewhere that they prey on moulting shrimps...so how do we prevent this?

    Or it is inevitable that we will end up only with the amanos over time?

    My case is that I do feed them regularly-once each in the morning and evening.

    I have also got plenty of places for everyone to hide in the planted tank with driftwood setting.

    And to play safe, I actually got the medium-sized Yamatos from C328, hoping any size differences will not cause any probelms.

    A fact is that the number of my male Cherry Reds are dwindling...

    just to share - the other day one of my sakura bigger size then crs was on top of the live crs chewing and eating the crs alive. By the way, it was the second crs being eaten alive. My sakura is bigger size than all my crs. So i guess maybe size do matters!

    Guess the general rule is that not to place shrimps of significant size differences in the same tank?

    Imo, their behaviour is not dissimilar to fishes. Fishes do attack other 'more sickly/weaker' ones; while most are known to be 'scavengers' (afterall, dead organisms are liken to food isn't it?).
    As in the animal kingdom, survival of the fittest rules, if your tank condition should allow that to happen ...

    IMO = in my opinion

    he meant that in the fishy world, shrimp and fishes are the same.... they will prey on the weaker or sick species (including their own species)

    i think its because your CRS is dying but not dead yet thats why the cherry prey on it... i've seen shrimps eating dying shrimp...

    i see. thanks.

    my shrimps doesnt do that now. perhaps due to the number of hiding place i have added for them.
