CRS Shrimps

Just a short video of some CRS,Snowball, Blue Bee, Tangerine Shrimps and a of course a few cory youngsters



Watch in HD if you can.

Love them all daragh thanks !

Daragh,

Thanks again for a wonderful video of some of your stock. All the tanks look in great condition as do the Shrimp, Cory’s and Crab.

What is the black substrate in the CRS tank, what do you feed them and what are your water parameters if you don’t mind giving out that information…………..

Thanks again,

Tom.

Was looking to get some of them CRS if you got some extra too

shrimp are lovely, nice high grade on your crystals (I'm jealous:laugh: )

any id on the ones I gave you?

Mrs Fishpatrick, not yet, I have not managed a decent enough photo. I need to set up a little photo tank and get a good close up of the head, I might get around to it today.

Ian, The CRS are not for sale yet, but when they are I will put them in the for sale section.

Tom, There are three different tanks there:

CRS are just below pH 7.0 24C TDS 30, the substate is Amazonia II. Also in that tank but not seen are the crabs I originally got as micro crabs but are actually about 4 times too big to be micro crabs and I have been unable to get an ID. I would like this tank at pH 6.5 but these days it seems very hard to get it there, for some reason.

The tank with the snowballs, the "blue" bees and they young cory is pH 7.4. 24C TDS 70 and aquarium sand.

The tank with the tangerine shrimp and crab is pH 7.8 24C TDS 70 and Amazonia II substrate, again I would like the pH a bit lower.


Daragh

Thanks a million for all the info and best of luck with all your efforts……

Tom.

well done and thanks daragh, that was a real treat.
a great video with interesting and healthy subjects.
the black crystals are beauts and the small looking cory with the big finnage is a cracker. what species is it?

The little corys are Corydoras napoensis. I left the eggs in with the shrimp to hatch and they have done very well in there, problem now is I want them out and there are dozen of baby shrimp etc., so that will be fun!

Daragh

Some very nice critters in there.
Probably the first time I've seen Anubius without a coating of black algae too

I'd say its a tough job maintaining all of those different params.

are cory napoensis one of the dwarf group. the tail fin is impressively large for the fish size. they look really nice.
do the shrimps tend to cross breed and whats the difference and relationship between the various bee shrimps.

They are one of the Elegans group, they don't grow particularly big a mediums sized cory I suppose. The adults are super looking fish with a lovely bright gold spot on the centre of their head. Must try for a photo.

Which shrimp you can mix with which is a complex business if you want to keep them pure, as a lot are just colour varieties selectively bred you can not mix them together as you will revert to "wild" types, just like if you mix different colour plastercines (or mala - that brings back memories) together it will all turn brown!

I could not list all the compatibilities (or not) without checking them as there are hundreds of possibilities with all the shrimp available now (although not necessarily in Ireland!).

The exception seems to be CRS where you can mix CBS (Crystal Black Shirmp) with CRS (Crystal Red Shrimp) and get one or the other - that is what I have read repeatedly at many locations, HOWEVER that would not explain why the first lot of CBS I imported were actually Brown and not black! I got some more and it was when I saw how black they were that I realised the first lot were brown not black.

There is also a "white" crystal shrimp, they come in two forms, gold white which is supposed to enhance the white is CRS and pink white which is supposed to enhance the red. I have a single male gold white in the tank featured so I will soon se if that theory works. Eventually the shrimp will all go to the lowest common denominator if you do not remove the poorer specimens.

The great thing about shrimp (a bit like some livebearers) is that the they gorw so fast and reproduce at such a young age within a few years you could develop your own strain with careful selection.


Daragh

thanks daragh, great information there.you are becoming a real shrimp guru.
do u think though that the shrimp colour can be affected by the environment.
never knew that about the plasticine.

I have given over eight tanks to shrimp and there may be more to come. I am becoming a big fan

Unfortunately my female Macrobrachium dux died just before dropping her egggs - this is not unusual, this time I retrieved the eggs and I am trying to hatch them artifically, should be interesting ...

Daragh

are u sitting on them

Not quite sitting on them, but they are still alive and I have proor thanks to Aldi latest USB microscope.

I liked teh idea of the low magnification, my other scopes are too high powered for some things and @ less than €40 I thought I would give this latest one a go. I got it tonight and within a few minutes it was set up and running, here is a quicj clip of one of the macrobrachium dux eggs 48 hours after the female died.

The flashes of light near the end are me using a penlight torch in addition to the built in light. I edited the clip with the free software which is very easy to use and it can also take pretty good still images. This was shot at 60x, there is 10X and 200X available too.

With a little more time and effort you could get some excellent microvideo clips and still images.




Daragh

WOW AGAIN DARAGH, YOU ARE THE MAN. YOU JUST KEEP ON SURPRISING US WITH YOUR INGENUITY AND EXPERTISE.

very good, you should do a series to show the continuing development.

Unfortunately they are all beginning to fungus, they were fine for three days and today they are covered in jelly like fingus, despite the presence of a couple of alder cones in their little container. Also I think they were too far away from hatching to reasonably expect to hatch them manually. There are a few single eggs around the container that still look good so I fished them out into a new container and might give one ago under the microscope again tomorrow if I get time.

Daragh

any update on the eggs/babies

No unfortunately they all fungused, they were not as near to hatching as I thought. Stripping the eggs from a dead female only seems to work if the eggs are almost ready to hatch anyway.

Bad news on the CRS and CBA in the original video in the first post, I lost a good few over the next few days and could not figure out why. Eventually it turned out to be the hardness of the water, at least the lack of it. GH was 1 to 2 or 17-34ppm. It should be around 5 of 80ppm, lower than this they have trouble shredding. Problem solved now I think. Fingers crossed.

what do u want them to shred, daragh.

excellent footage daragh fair play to you. Its a bit freaky to see something that is so small up that close. I am curious to see how you get on with your breeding programme. You just better be careful you dont create a monster.... and thanks for the laugh you gave me when discussing mala. I hadnt thought about that in years but it is true it does all go brown. I never thought of it happening with fish or shrimp breeding but I suppose it makes perfect sense when you think about it.

As usual you have increased my knowledge and given me lots to think about. This hobby will never get boring thats for sure. Thanks for sharing

lol I give mine my utility bills to get rid off!

daragh.
what are the optimum conditions ph temp etc. for the cherry and red crystal shrimps.
