Hi all, I would like to check if anyone of you has bred this species before. If yes, will does it need brackish water or freshwater will do? :huh:
I got 2 pregnant pearl shrimps right now and they are carrying the eggs for over a month now. A wee bit long I would say. :undecided

Got a pic of the male shrimp. Will try to snap the females if they come out. They always hide. :rolleyes:

Hi Kross, you're in luck! If we're talking about Macrobrachium cf. mirabile - "Pearl shrimp," they do not have a larval stage; they hatch as miniature version of the adults, so no extra steps needed.

Congrats on your pregnant Pearl, hope she's successful in caring for them until they hatch, which should be in the next week or two at most (takes 4 - 6 weeks, depending on temperature). :)

Hey Kross and Jojoecute, I've heard that Pearl shrimp are the very few Macrobrachium species that are peaceful. So is that true?

My Macrobrachium species (M. lanchesteri) are predatory and will kill and eat small fish and even kill each other, so my one remaining one lives alone.

Good Luck, both of you on your pregnant Pearl shrimps. Keep us updated on any hatchings. :)

Hi GB,

I got 5 pearl shrimps living peacefully with my boraras brigittaes, crs, malayan, oto and apple snails in a 1ft cube tank. :D

Base on my observation, pearl shrimp doesn't attack the others at all even when they are rite beside it. Their pincers tends to avoid other shrimps when they searching for food on or beneath the gravel. It is only aggressive when there is live food and they'll fight for for it but no harm done. :)

Wow, your shrimps as well as pictures look really great, kross! I keep the same species for a while now but found no pregnant females yet. Ok, I don't feed them but they get some flakes, frozen food etc. while feeding the fishes in my show tank.

Your shrimps show lots of black spots which looks really nice. Do you use a dark colored gravel? My shrimps adapted very well to my grey granite gravel and hide perfectly. I have to look at leat twice before I can find all of them. They hide that well because they got exactly the same color than the gravel.

best regards

Robert

Mine went almost the same color as my terra cotta gravel! Interesting shrimp, indeed. Great pics, too. Don't forget to keep us updated about the babies. :)

Thanks for the kind comments guys. :)

I'm using dennerle black quartz gravel. The shrimps were initially having more white spots than black when I bought them. I guess they are really good in camourflage! In a matter of days, they shifted from white spots majority to black majority! :D Very interesting shrimp indeed. :happy:

What happened? Sucked into filter? Or didn't survive?

Not sure. I was on business trip and when i got back, the mama's (x2) sag were empty. I check around the tank and not even 1 shrimplet. :cry:
My filter inlet is covered with sponge. Maybe it's the 2 rasboras brigittaes that ate the shrimplets???? :huh:

Anyway, one of the mama shrimp is carrying eggs again. Wow, that's fast!! :D

Realy strange, i'm having the same experience as you :( I have 4 female and one male. At one point all the females where carrying eggs but not ones have i seen a shrimplet. I don't keep any other animals together with my shrimps, there are plenty of hiding places in the tank, also for the shrimplets (javamos)but nothing happens :undecided

I think you can try keeping substrate half black half white.. then when the shrimp and shrimplets cross from one half to the other half they will stand out distinctly.. just a crazy idea.. lol
