Just some quick snaps of the adults who came out in force to feed on some high protein pellets. Really happy with the progress I've made.. I plan on moving these to a dedicated tank soon to increase the shrimplet survival rate as they were breeding much better when I kept them in more suitable parameters.

Now it's time for a little update :) Paracaridina Blue Bee: My Little Reef 28L: Some my New Shrimp ( Aura Blue and Rote Tupfel) My PRL: And my SCR: Thanks :) And My Sulawesi :

That sucks to hear mate. Yeah zebs are a bastard to crack. I've been working with them for a number of years now and still dont feel like I have them pegged. Was it calcium chloride or calcium carbonate that you got? Calcium chloride shouldn't be used in freshwater because freshwater organisms dont get much exposure to chlorine ions. Fine for saltwater tanks (the bulk of sea salt is sodium chloride), but not fresh.

Sure, will do! I might not have any luck with shrimp breeding yet, but I have around 40-50 snails and they keep increasing!

Crushed coral... or mineral stones like seyru. However, they will also increase pH and other parameters. Water changes could be stressful. The easiest way to raise it is to get a GH+ remineralizer.

No. The saddles are in the same spot regardless of shrimp species. Colors of the saddle and eggs can vary between individuals, colors and species. Here is a low grade female. The saddle, or ovaries, are the yellow/white area in the middle of her back. It looks like a "saddle" that you might see on a horse. Females and high grade males may also have stripes from head to tail. This is normal. Lower grade males don't typically have stripes.

Females are larger, "rounder" and normally better colored than males. Heard one trick a person uses, right when you turn on the light, capture the shrimp in a net and bring the shrimp up to a light. You might be able to see a saddle on the females when they are palest. (i.e. after it's been dark all night) On yellow shrimp, the saddles are easy to see in mature females.

Just thinking outside the box for a moment... could there be anything contaminating the water ? Airborne even? Some piece of equipment made from bad plastic or coated?

They look to be females to me due to the "skirts".

YEah for sure, still ended up getting pure calcium chloride from bulk not damprid from woollies (which I'm sure is still damprid haha) Update: I noticed a few more individual deaths over the last week, one per day on average, my colony has demonised to under 20, So had to beef up my processes etc got some new equipment for slowly dropping water in- makes life easy. also I got sick of them hiding under the sponges and figured they don't feel safe or have anywhere better to hide, remembering when I first got them they swarmed to a bit of driftwood in the tank, so I swapped the plant on lava rock for a small piece of driftwood with anubias and Java moss. By this point I don't think much else I do can be negative considering they are dropping off regardless- short of randomly changing they're WP which never happens lol So in short massive kudos to fishmossy and anyone that does keep/ breed these, as I won't hesitate for one second to admit they are clearly beyond my care and I'm not sure it's fair to the species for me to try these again which is a little heart breaking but yeah. I had a really bad start to be fair, but my last lot should have at the very least survived, tank doesn't get over 21-22c and is very well matured etc. nice healthy biofilm growth, stable ph of around 7 and WP with tds ranging from 17ppm to 27ppm max. Generally stable. so out of like 37 from this lot there's bugger all left. Saddest face ever. Thinking the go is a flow through system that takes in like 50ml a few times a day and output a little more then that back into the tank. A bigger tank may also help but I doubt that's my issue they were in a bigger tank when I first got them. eh I tried Verdict? These guys don't want to be alive, they've evolved over how ever many hundreds of years to not survive. Pretty bad trait to pass onto your children if you ask me haha A great example of how delicate Eco systems can be, these guys will be extinct within 20years if people don't successfully breed them in aquaria. The slightest change even a construction worker accidentally dropping a large reactive rock or bit of cement into they're river and the zebs will be screwed for miles. Scary tbh.
