How to pick healthy caridinas at the fish store

Recommended Posts

jojowhisky

Hello everybody!!

I am about to make a trip down to the fish stores to hopefully pick some crystals to replenish my first tank that i started(the 16litre).

It is very stablized right now and houses the bloody marys and 2 surviving crystals.

The bloody marys have acclimated to the parameters nicely since the majority of them are juvi shrimps that have been birthed in this caridina parameters.

My question is, what are some of the things you guys look out for when picking out caridinas?

I would appreciate some pointers as previously i was busy trying to get my parameters right and the basics of doing good water changes so i have not been buying new shrimps. But since now im ready to get some crystals, i realized i need more input on how you guys spot good shrimp quality.

Things have been going great with the temps of both shrimp tanks, they range at 21 to 23°c. Tds is kept at 200 for the yellows and 180 for the crystal/bloody mary tank.

Currently have got 2 berried yellow mamas, she must have hatched all of her babies wen i was in japan coz now i see two berried mamas and plenty of small friends swimming around.

So very happy.

I foresee culling in this tank soon, as it is only a 10litre and i did not expect the population to be increasing when i started this tank.

Again, thank you to everyone here that helped so much in my learning process.

The shrimps that i hatched artifically have grown to a considerable size as well after i came back, saw 2 in an adolescent size? I assume they are from that batch.

Regards,

Jo

Good to see you back and great that everything is going well now.

Usually you should try and get juveniles as they are better at adjusting to new water parameters, but that is assuming they have juveniles, which they may not! You can't tell whether they are male or female at this stage though. If they have adults you can choose how many of each you want (if my memory serves correct the 2 you have left were males??? but I can't find the photo/post-my bad) but as long as you have some of each sex I am sure that your setup is now settled/constant enough that they will quickly breed (they aren't as prolific breeders as cherry shrimp though, smaller groups of babies and they don't reproduce until 6 months old). The only other thing you can look at really that I know about is whether they are lively/active, with good solid colouring. As you already have plenty of shrimp keeping success I think you can safely rely on your own judgement in that respect? Others may have more advice? Mine have always come in the post so I didn't get to pick them?

They are a bit more sensitive/delicate so slower drip acclimatise them than the neos.

Look forward to hearing/seeing what happens next!

Hi simon!
Yep you are correct. You helped identify those 2 crystals to be male.
Well, i highly doubt im gonna be able to get juveniles here, they mostly sell adults.
Also, i do not really know how to tell male from female yet. Have watched a video you shared with me on how to sex them but i still lack that area of ability for some reason. (Schooling myself more on this)
Will take note of what you mentioned and look out for lively ones.
Thanks for the information on them breeding slower. I had thought they would have the same prolific breeding capabilities like the neos.
Will drip acclimate them real slow. I just remembered how sensitive they are when you mentioned it to me.
Fingers crossed!

If you are allowed to pick the shrimps yourself, then pick all the females (since you already have a couple of males).

Good solid colouring, check for genetic defects, active ... I can't think of any thing else.

Bring your TDS meter with you to test their water parameters. If you have a pH pen bring that too.

It's best to know what water the new shrimps come from so you can tailor acclimation to their water params.

Hmmm went to the fish store to take a look at their livestock of crystals.
Did not like what i saw, lots of dead ones in the tank and some had the creepy planaria in it??!!?! (This slimy friend still creeps me out)
Decided to go with a guy that takes his shrimps from a breeder. My yellow neos came from him and i remembered the water it came in was good.
He sent me a photo of the guys.
Hope all goes well.
Picking them up on monday.853b2fe603627771563273aa8b3257e0.jpg

Hope all goes well with getting the new shrimps, those in the picture look great.

Perhaps watch the video on telling the differences between male and female shape just before you go? If you are getting them from a breeder he can probably  tell which are which for you anyway!

You were very wise to stay away from unhealthy shrimps from a tank with 'planaria', that could have been a BIG mistake????

You think those look ok?
Well, if you think they do, they are probably good.
Im really excited to be collecting them on monday!! Have not had crystals back in my main tank for a long time ever since the last colony was wiped out*sad*
Hope they make good company for the last remaining two in here.
Yes i will watch that video again later tonight, need to really school myself on how to sex shrimps.

      Glad we can be of some help and I agree you are doing the best thing by thinking it out thoroughly before you get started. It is very frustrating when you spend a lot of money on a small setup to then have to go and do the same again for another setup because it isn't big enough, way more economical and cost effective to get it right first time, though as you say you are starting with some of the stuff! I'm also sure that when I closed down the small one and moved the shrimps to the new tank that I probably lost half of the shrimplets as they were too small/young to be moved in reality but I really didn't want to have to run 2 tanks for a few months whilst I waited for them to grow - I had way too many anyway. I can't be much help regarding the 'chiller' as we don't have hot enough weather here, in fact even the humans don't get that over here (except in expensive cars)? A lot may depend where you are placing the setup as well, mine is in a dark corner that doesn't get any direct sun. If it isn't likely to get too hot there for a while you can of course come back to that as a separate issue as it won't mean disrupting anything in the tank anyway should you decide to get one later!  You are probably best steering away from the CO2 as it is one less thing to set up and, as you, I have read a lot of reports saying it isn't good with caridina shrimp setups, though I have no actual experience with it, but why risk it. Hope you will keep us informed/updated. Simon

      I agree with you both and you have changed my mind. I will go for mix of cardinia shrimp. Definately will be lot more interesting in terms of colours and patterns.   I do already have most of the stuff. The only thing that I do not is the Chiller and even though I do have the KegKing Co2 setup, I will stay away from it because its a cardinia setup. Will research a bit further into the chiller this, as I do not want to buy one for a small tank and realise that I need to invest on a bigger one down the line. Thank you guys for the input. Really appreciate the insight. P.S: Great pics Simon. That has certainly swayed me towards a mixed setup.

      I started out with a 30cm tank, and it's my only shrimp tank, started of about November with Neo's and added a few Taiwan bee's, king kong, wine reds, pinto's and blue Bolts around feburary, my Neo's have multiplied, but given many away, and finally giving most away, leaving only cardinia, my water seems ok, since many of my cardinia are still here, and my Taiwan bee have berries, shrimplets should come any time. I think you should be prepared to spend money, for me I have a HOF, CO2, water cooler and the right light, i'm intend to change the current substrate from ADA to the PB, but have to wait for the Taiwan bee to have shrimplets.

      Having multiple tanks and a tank rack may be where you want to go eventually but that is probably for the future? If you want to test out the cardina you may want to go the route I did in that having a mix of shrimps colour and pattern in one tank is certainly more interesting to look at than 10 tanks with single/pattern, and I keep getting new ones that I didn't have before, even the boss should like them!!!!! It is obviously a lot cheaper and takes up a lot less time and space as well. I got the 35L dennerle scapers tank (used 3L of substrate) and it is 40cm x 32cm x 28cm and it has 28L of water (my measuring jug is a cheap one so maybe inaccurate, but the tank isn't filled to the brim and stuff in the tank takes up some space). It would give you an extra 10cm x 32cm (plus 2cm x 30cm) which to shrimps is quite a lot, not that I am saying you should necessarily get this tank but just as an example of how less height (which isn't needed for shrimps) in a tank can make a lot of difference to the floor area of a 'similar' capacity tank, but you may think it is too much money for such a small increase, but obviously there is a whole range of other tank choices out there.I assume you would use the heater/light/filter etc from the old tank if you weren't going too much larger? And, of coarse, you can just stick with the tank you have and that should still work out fine for a starter/tester tank? If you want to see the mix then just click on gallery/New images and scroll down. You should show the boss and I a sure it will swing it in your favour! I don't think you should have any problems with caridina if you are sticking with remineralised RO water and proper shrimp products from the very start. It took me years to get to where I am now but I think ALL the problems I had were because I was trying to use 'tapwater', as soon as I started with RO remineralised no problems whatsoever. Any other specifics/question feel free to ask away. Simon

      Thank you very much Simon. I have certainly thought about the idea of secondary tanks. But i wanted to test out the Cardinia waters first. If they do capture my interest, I plan to seek my boss (aka wife) to approve the shrimp tank rack idea *fingers crossed* I have been going through this forum and the Shrimpspot forum to gain as much knowledge as I can to get a good start. Thank you again for your message. Every little bit helps.
