CRS Tank Log

Recommended Posts

Lizzy

Just a thread where I can share photos of my CRS tank and shrimp. I got the original CRS in November ‘18 and they have been breeding fairly consistently since. 

Sorry the photos aren’t great. They’re all taken on an iPhone 6.

Please share your thoughts 🙂

Thanks

They are very good photos!

If you want to fill us in on your tank and experiences so far I am sure there will be many people interested. It sounds like you have done really well if you only started 6 months ago?

I had crystal red shrimp years ago but never had any success with them, and they all died off over a period of about 12 months. I think a number of factors caused them to die off, the main issue being that the tank wasn’t dedicated to the shrimp. I was using pressurised co2, fertilisers etc. to grow plants in a newly setup tank. In hindsight, I was making life hard for the shrimp (and myself 😅)

Things are going 100% better this time around, and I believe that’s mostly because I’ve put them in a well established, mature tank.

The tank the shrimp are in now has been running for years and has had the same ADA soil in it for at least a few years. The soil no longer buffers pH as it’s so old. I just tested the pH out of curiosity and it looks like it sits around 7.0-7.2. People would typically suggest that pH level is too high, but the shrimp seem to be flourishing so I don’t worry. 

I use 2 HOB a style filters. One is a decent size Hagen brand filter and the other is a tiny AquaOne. I could probably get rid of the smaller one.

I try to do 2x small water changes per week. I use a dechlorinator then leave the bucket of water to sit until the next water change. I use tap water and don’t have an RO unit. Pretty simple. 

I took photos of the foods I’ve been feeding. There are so many shrimp-specific foods available but mine seem to do fine on these. I took the feeding photo 5 minutes ago.

I should mention I keep RCS in the same tank and they don’t seem to bother or have any impact on the CRS.

I’m hoping the CRS population starts to take-off soon. Plenty of breeding happening and babies seem to be surviving so I can’t see why not.

Thanks for reading

Thanks for sharing and it is good to hear that it is going well.

I had the same issue with the PH being 7-7.5 but mine didn't seem to mind either so I left it. It does seem that if the PH increases slow enough they can adapt quite well. I see you have babies so those will be used to the higher PH.

I hate those ridiculous tests where they have 3 shades of the same colour indicating different Ph as it makes it almost impossible to tell as it depends on the light when you do the test.

You may find that you don't get an 'explosion' of crystal babies if you are using tap water, but that is my experience with tap water but maybe your tap water is better in Australia. Cherry shrimp are usually fine in tap water, even in our water here. The cherry type are much hardier and as long as the parameters aren't too off will live happily enough with Bee shrimps, as you say neither dominates the other type. Tap water is always a bit risky as the water companies can change the parameters without you knowing and if the have to do repairs to pipes/equipment etc there can be all sorts of things different in the water so just bear that in mind, especially if you have deaths - that maybe what happened before, though as you say CO2 and ferts aren't good with shrimp as well!

I think the thing to do with foods is use a variety which is what you are doing already, and after all is said in done you still feed the same amount so it means each will last longer so it isn't even money saving to just use 1 type.

As they say though, IF IS NOT BROKEN DON'T TRY AND FIX IT, so if it is fine and it looks like it is just carry on. IF you don't have success with babies, and you don't really want too many anyway just bear in mind they do better in RO remineralised water. This youtube video is very good and interesting and covers most shrimp stuff so it is worth watching even if you aren't having a problem:

 Thanks for sharing and the photos.

The colour chart tests suck. I don’t know of any alternatives though and I rarely check pH etc. so it doesn’t really bother me.

There are definitely risks associated with inconsistent tap water parameters. If I have dramas in the future I’ll invest in an RO filter system. So far so good though. As you said Simon, if it ain’t broke, don’t fix it..

I noticed more fresh babies this morning 😁 I would say there are 15+ babies in the tank at the moment. 

The photos are crap but I think this is my best shrimp. The white is much brighter than the others and the colour is very solid. I hope to have a tank full of shrimp likes this eventually.

That shrimp does have stunning colour and even the other one is pretty good. The best colour one looks like a female to me. They are very good photos I think.

There can't be anything wrong if you are getting babies and they survive to adulthood. When I tried tap water with crystal shrimps I would get a few babies but they died within a few weeks unfortunately. I now use a zerowater filter jug to filter the tapwater and that produces RO water.

Shrimps are prolific breeders so by using tap water you may even have the advantage of not getting 'too many babies' which is the usual problem..............

Cheers for the feedback Simon. 

I can’t say why they’re breeding and surviving, I’m just glad that they are 😊 This is the most babies I’ve seen since November.

I’m excited as I have shrimp at all different ages now, which indicates the population is growing. This photo shows an adult and two younger shrimp together.

Another great photo. I can see you have the whole range of sizes, and some red cherry. The red cherry don't look to be adults yet so I assume they are breeding well also?

Keep it up and you might need a bigger tank....................... always good to hear of a success story!

      The tanks are only 16L, for it to reach 31c, it isn't hard.
    • jayc
      Sorry to hear that.  Wow, the temperature must have been very hot for the water to get to 31degC.

      It's room temperature, during the past week Hong Kong has become an oven. I will get another water cooler before I start again. The 3 shrimps seems to be doing well for the past 11 hrs.
    • sdlTBfanUK
      Well, what can I say, de ja vu, was it a heater malfunction or just ambient room temperature? I wouldn't hold out too much hope for the 3 survivors either if my experience was anything to go by - but I will keep my fingers crossed they survive! Really sorry to hear the news and if anyone can feel your pain that would be me. Hopefully you can just remove the cooked shrimps and start again without having to go through the whole process of re-setting up the tank and cycling from scratch like I am? Hope everything is going well with the old tank. The shops sound similar to ours in old towns, they started as houses and then get divided to shops street level and basement and the upper floors are either offices or residential. Simon

      update, some upsetting new, all shrimps except 3 has died in the new tank, as the water in the tank went upto 31 celcius, the other 3 was half dying, I put them into the old tank, and seem to be ok for now.
