Red Rili Shrimp Sex Identification

[snazy]

It's beautiful. It's amazing how well it's grown.

I can't take the moss off, it's attached to the wood so it's going to wait Below is a picture of the tank from a week ago(it's a mess)and some shrimplet pictures. Some of them are really red for such small guys and some have taken after mom

I can't see any rilis but there are quite a few shrimplets around so hopefully. It seems to me they've deffinately got different colours even when very small.

The following two are some rather colourless shrimpletts, not great pictures but shows the difference in colours:

Yeah with the shrimplets unless your looking at them through a good magnafying glass its hard to see any real colour charactistics. Most of mine I can only be sure what colour/ pattern they are going to be once they are almost fully mature, and even then the females just keep getting darker red.

The tank seems to be infested with the little ones. I am shrimp overstocked

There's definately two sizes of them or at least there are some half the size of others. The cory babies seem to have no interest in them at all. They eat alongside each other. More pictures:

Great pictures, if you think your shrimp overstocked now just wait till they really hit their straps

. My corys have never shown interest in shrimplets or adult shrimp either. The only fish I have seen (aside from a goldfish- not mine) eat a shrimp was one of my Khuli loaches munching on a dead shrimp it had found and my sparkling gouramis used to nip at the shrimp and eat the shrimplets. Sometimes my fighters have the odd snap, but they have never eaten enough to deplete the ever growing population.

The sick shrimp is still alive, saw him yesterday catching fish flakes and he's made a home in a cave in the driftwood. The other shrimp in the other tank and shrimplets look just fine, none is showing the white muscle disease. Strange sickness it is...

 

[Baccus]

Yeah, it seems to have many potential triggers and what we can easily see (the whitening in the shrimp) can infact be almost any number of shrimp illnesses that display the same basic symptom. But I do know that keeping the shrimp in a clear under populated tank with good food, it can survive for quite a few months. But I have not heard of any shrimp actually making any sort of recovery.

 

[snazy]

Yeah, I presume he won't recover. If it was nothing, he would have recovered already. It seems it kills them slowly. Hope he doesn't suffer much.

 

[Baccus]

I would hope the only time it may suffer is when it has trouble moulting and if it's legs dont grow properly preventing it from moving around easily and foraging for food.

Thought I'd mention, but today I saw 3-4 of the small shrimp already saddled. Wow, if I knew that at this size they can actually be sexually mature I wouln't have had any doubts about the rili shrimp being males in the beginning of this thread.
Anyway, I think there are some rilis from the cross too, one is a saddled female I also saw today but need to wait for a bit longer to see how good looking rilis they'll turn out to be.
There are some fairly dark red small shrimp, some normal reds, some more pinkish,even saw one that looks clear at the moment, and the rili looking ones too of course, so it's getting interesting

Edit: By the way, the sick shrimp is still doing fine from what I can see. Feel sorry for the lonely thing. The rest of the adult shrimp in the other tank are fine. The only female adult cherry has not gotten berried since the first and last time, not sure what's her problem but she's eating like a pig otherwise and all are fairly active, not one bit afraid of the corys which is very funny as they keep landing on top of them or eat alongside each other.

Some pictures. They are from just over a week ago:

My shrimp aren't really scared of my cory's either, I don't know if its stupidity on behalf of the shrimp or just that they know my fish generally dont eat them. I have even watched the cherry shrimp all but throw themselves at my Pakastani loaches mouths and still not get eaten.
Good to hear that your slowly finding more babies and yep they do get interesting as they colour up

, its a bit of a lucky dip with each new batch of shrimplets.
Also interesting that the sick shrimp is still going, shame it has to be on its own but for the best, unless another shrimp develops the white body and then the other one can have company.
Not sure if you would have seen the pictures of my own breeding project.
Here is the male

And one of the females I put with the male and one of their non red offspring in front of the female

 

[snazy]

Lovely, let me know how they turn out..I've got a lot of young shrimp, can't count them even so hopefully there'll be some interesting ones but if there isn't, I don't mind either.

 

[Baccus]

I am hoping that the non-reds turn out to be at least chocolate like their dad, but personally I reckon he is more of a coke colour. I gave their tank a massive clean yesterday, because I am sick of the snails in that tank, and am hoping that getting rid of the bulk of the snails will enable the shrimplets to grow that little bit faster.

 

[snazy]

Yeah, I am infested with snails in the fry/shrimp tank. They like to gather on one spot at the back next to the air stone for some reason and I scoop them and throw them in my clown loach tank so not too bad
