Do shrimp eat their little shrimplets, my Crystal Reds keep breeding, and I see some littlies, then I don't see them anymore and all I get are one or two out of a batch.

PH 6.0 Ammonia 0 Nitrites 0 GH very low. Using rainwater and a little tap water.

What are your nitrates? Also what does very low gH mean? Do you have actual values?

Do you feed anything special for the shrimplets?

It's rainwater so it's low, it only takes one drop to turn yellow, nitrates shouldn't be a problem. I don't feed the shrimplets they're in with the adults so they just get the same food, lots of algae from Java Moss, boiled lettuce and Silverbeet and Fish Flakes and pellets.

So GH would be <20ppm (assuming based on the tests I've seen).

That could be a problem as little shrimplets molt regularly (i.e. daily) and molting problems are often associated with low gH. Do you have values for KH? Or TDS?

Sounds like there should be enough food for the shrimplets (and the adults). Maybe feeding a pellet that breaks down to powder could guarantee there is enough food for the shrimplets. However I'd be looking at gH first.

I just checked GH around 40 or a bit higher KH less than 10. I use Viformo which breaks down into powder and other pellets which don't.

Its more likely that the shrimplets are dying of other causes than being eaten by their parents.

Yeah I don't know, I only got these a month ago and they're breeding like rabbits, I've got two more females ready to pop anytime. Do people separate the female from the colony or just keep them in there.

Looks like your GH is too low....should atleast be 4 or 71+ppm.

Too much rainwater by the look of it, I'll have to put more tap water in. They like breeding in this water though, I only bought about a dozen a month ago and I've had 2 batches and two ready to go.

Ive just checked my tap water GH 80 KH 30 looks like I'll be using straight tap water.

looks like I'll have to steal some water off my Fronnies.

Nice fronny. Whatever you do to change water parameters, do it slowly so you dont shock your shrimp.

Mpimbwe, yes all I have to is find out how to raise the KH And GH without raising the PH and killing the Shrimp, should be easy, not.

Any advice?

Your pH is 6.0 so can afford to come up a little bit (6.2-6.4).

I would just mix up a bit of water that is at the ideal parameters, then use it to make small water changes every day. That way the water parameters in your tank will slowly change to the ideal water parameters.

I'm going to have to do a course in chemistry I've got too big a diversity in fish and now Shrimpies. I've got fish from Lake Tanganyika, Fronnies, Tropheus and Lelupi, the Amazon, Discus, Rams and L numbers and now Shrimpies and I don't even know where they come from.

Up until a few months ago the only shrimp I knew about were King Prawns, that's probably why I like Red Crystal Shrimp they look the same as cooked Kingies, yum.

Well I won't be available for a while, I'm going down to the lab with my master test kit and work on a new batch of Shrimpies water.

I just went down to mix some water and the berried females and a couple of shrimplets were out and about so I took a couple of photos with my trusty HTC OneX.

Beautiful fish and shrimp mate!! can't imaging the parents would be eating the shrimplets. Do you have IAL? I find the shrimplets graze on this from early days! Also good shelter for them. What kind of filtration are you using?

Sweet looking shrimp & fish dude, gotta love the CRS, they look like little candy canes, very cool! :victorious:

Solution

Just using two air filters, I'd stick them on my FX5s but that might end in tragedy. What's IAL never heard of it.

I think I've just worked out the solution to my problems, if I can't raise the GH too fast they can bloody well eat it. 10 minutes after I put it in.

We love calcium carbonate.

What's IAL never heard of it.

Indian Almond Leaves (IAL).

Secret ingredient for all Amazonian and Asian fish keepers and shrimp keepers.

Check out the SKF library.

I have heard of it, thanks, I'll give it a go. Mate those Asian fish keepers make us look like noobs, I've seen a guy sitting on a footpath with about a hundred goldfish in a bowl selling them, I think he just sprayed them once in a while to keep them wet, there was no room for water.

The Fish Street in Hong Kong should be on everyone's bucket list.

I see what you did there ^^^

Selling fish in a bucket like that will never fly (or is it swim) with the animal activists here.

      @jayc or anyone else, could you please go over how to dose this oregano oil in water, just to make sure I don’t nuke my tank. I only have my tiny HOB and dual sponge filter. Oil will be here tomorrow and I’m nervous about killing my tank. Filter media will be moved to a 1.5 gallon  tall container( beverage type container thAts tall and deep), with the sponge filter. I’ll leave the HOB without ceramic media etc for flow during treatment. I will be taking a gallon of  tank water out for the container my filter media and sponge will be running in for a few days, before dosing.    I places a blanched cucumber in tonight, they swarmed it for the first time, ever. Looking at the shells on some of them, it’s 100% bacterial( external as well as possibly internal). I don’t know why. I thought my water was in good shape..... I’m terrified of something going wrong. Hopefully I can get it all together, and this is successful.... also, than you all for the help. It’s greatly appreciated.
    • Steensj2004
      Shrimp on the oregano leaves! I don’t know, however, if they can get anything off them. I blanched in boiling water for 30-45 seconds, but they weren’t that soft.....
    • Steensj2004
      Um, because I’m all over the place I thought it pertinent to mention I’ve slowly lowered my GH to 5-6 over the last week and a half, or so. Slowly, but these shell issues existed long before adjusting the water parameters. I suppose it’s possible this could have finished off the injured shrimp, however, the parameters are, from what I can gather, a little more superior at this time. The GH was lowered by monitoring my TDS drop closely. I dropped the TDS by around 2 points daily. At this point, I’m sitting at:   PH: 6.2 GH:5-6( during testing, the color teeters between 5-6 drops for a change) KH:0 TDS:140 Temp: 72f   So, now that I’ve completely sworn off of fertilizers, I haven’t seen any increase or decrease in TDS / GH without my own manipulation. Second and third generation of shrimplettes are doing well, and aren’t showing any signs of discoloration. Another mama likely soon to drop as her eggs have easily visible eyes.   
    • Steensj2004
      I apologize for being unclear. I had ordered one before asking more specific questions. So I simply located a different one and order that( the one you green lighted), while also canceling the less desirable one. Also, the one you told me to buy, was considerably cheaper, while retaining the same no additive ingredient list.   No signs that the oregano leaves were touched this AM, but, there were multiple shrimp surrounding them, while several were perched on them. I’m not sure how much they need to ingest to really help, but hopefully the sampled a little bit overnight. Now, my problem is locating a food that they will attack, to place into the tank. Would it be possible to mix some BacterAE/ Shrimp Fit powder into oregano oil water? They seem to feed on that when it’s added to the tank.... otherwise, I’ll use some rephasy, newt made, with oregano oil water added.... or something similar. 
    • Steensj2004
      In relation to the PH, what is too low? Because several people in other groups act shocked at my PH at 6.1-6.2. The substrate is ADA and has always buffered to that range. Even the Fluval Stratum I used in the smaller 5 gallon buffered similarly.
