Eliminate rotting materials, change water, decrease places for them to hide, add a hungry macrobrachium, maybe a crayfish or two, don't feed the tank (or feed it very sparingly) til the planaria are gone. That was my method anyway.... they're not visible anymore, but since I never really touched the ...

The eggs are fertilized on their way out of the female.... so they are fertilized before they are seen on her tail. If they aren't fertilized by then, the eggs will probably be gone within a day. If a female has eggs on her tail for more than a day, those eggs are probably fertilized. The lighter ...

I think the transfer to salinity is key, but in my experience, the first day is a fine day to do it. However, I still believe they should be acclimated to the new water's chemistry (and Temp, if necessary) in two, preferably 3 steps, for most of the animals to last the first 4 days. Like from fresh ...

Ohh..... just a note, that batch I mentioned in my last post failed. I think the environment wasn't aged enough, and I haven't tried again yet. There was also a terminal event around day 14 where almost all the larvae seemed to have beached themselves on the side of the glass overnight. This may be ...

At the stage of these pics, I would say that they can't be sexed by appearance yet.

Actually, all I can say is that the very first time I kept these, I kept 4 in one tank since around the time they were about 1 inch long. I knew little about them and they canibalized each other over the next few ...

How are they doing? When I had Green shrimp hatchlings, they were very active too, constantly swimming around, and fun to watch. However, they died off over the course of a few days...

Sometimes if shrimp are seen swimming very actively all the time, seemingly in the same patterns for no apparent ...

Thanks, that sounds pretty good. I'll look into that model.
I've also had concern about some of these pumps raising the temperature of the water (near 80 F or a little more) in a smaller aquarium. For most shrimp it's not a big problem though. But there were some shrimp I wanted to keep under 75 F ...

I doubt that they breed in their enclosure. My guess is that they have a screened off section of wild area that captures upward migrating postlarvae. When the shrimp in the enclosure are large enough, they are harvested. Meanwhile, there's always a mix of sizes because small individuals are ...

They especially would enjoy a submersible water pump with its water jet pointed at a rock or driftwood. Even a small one would do... The shrimp will be drawn to that area. Thiis would disturb any surrounding plant setup though. Also, Cherry and Green babies would be at risk of being chopped up in ...

Oh, I forgot about this thread. You guys are right about the markings (although I don't know of any link to the sex). Depends on what kind of habitat they're in. I had my memory jogged by plopping a juvie into a new tank about a week ago. It got those stripes...really dark too... and also a orange ...

How safe is newspaper ink for shrimp?
I know people use newspaper for various things in the aquarium hobby - both wet and dry jobs. For example, some plant dealers basically wrap their plants in newspaper, dampen it and seal it in the plastic bag. This seems to work, but there's no doubt the ink ...

I believe at that size they're too young to sex just by looking at them. I don't know about the lines though. Young M. rosenbergii that I've seen have always looked more or less like clear ghost shrimp. I've never noticed distinctive lines on female adults, myself.

I don't know what the first sign ...

I mentioned doing this recently in another thread. But all I did with mine was take a ~5-6 inch long rock and prop it up against the front glass. That rock had a relatively flat bottom, so against the glass it formed sort of a triangular tunnel that I always have a nice view inside of. One of my A ...

My experience is with driftwood and Cherries and Amanos. And it seems not to be dangerous because the Cherries have regualrly bred and the Amanos have produced eggs and larvae. Even when the tannins have occasionally deeply tinted the water. This is an extreme example too because the driftwood in ...

I saw that. aquabid pic:

It looked like a shrimp in the Atyoida genus to me. And it may be Atyoida pilipes

Those seem to be really variable in coloration, and the most available ...
