This is very informative. Thank you for sharing your experiences. I have wanted some Cardinal Shrimp ever since I first saw pictures of them but my inexperience and lack of funding has kept me from getting any. Now I have some cherry shrimp and I've been working on the basics with keeping shrimp. I'm curious to see how your shrimp do as time goes on. What I hear most often is Sulawesi shrimp need perfect water conditions (Ph, temp, Kh/Gh) in order to survive. Do you have much fluctuation in Ph and Temp? I keep hearing these guys are fragile but so far you seem to be having success. I hope all continues to go well!
I too, prior to owning some myself, have read that they're very fragile and require pristine and perfect water to survive. I wasn't sure it these were facts or just overly careful hobbyists who baby their shrimp simply because they are expensive specimens. And yes much as people don't want to admit how OVERKILL they are sometimes in terms of care for their pets, it does happen very often. By overkill, I mean people who go the extra mile plus 10 more, and that extra 10 miles has negligible effects to their pet, sometimes it's even damaging because they're not allowing nature to take its course!
Right now, I do not believe that the Sulawesi shrimp are as demanding as people claim them to be. I will still classify them as an expert level shrimp but certainly not something that dies if their PH drops by .2 or when temperature goes down to 78 when it was 82 degrees 24 hours ago.
I don't do water changes in this tank, only top offs. I use dechlor tap water and our dechlor tap here in San Jose is about 7.6 ph, medium water. I've topped off with RO water before, but that was only because I was too lazy to get my prime and fill up my bucket. When I do use RO water though, it was 100% RO water only and had no ill effects to my shrimp. I have somewhat of a lid on it, so top offs don't occur very often as it minimizes evaporation. During the hotter days here in CA, my tank lingered in 80-84 day and night. With the colder days coming in recently, my temp flux from 78-84. Still no ill effects and they do just fine. I cycled the tank with Sulawesi shrimp for crying out loud! People probably think I'm crazy but eh, I did it. Do I recommend others to do it too? Certainly not! It was simply a miscalculation on my part. I originally figured that a simple seeding will let me cycle my tank for them. I only took into consideration the shrimp and not snails. When you add on the 25+ snail bioload... that's a whole new story there, thus triggering my tank to cycle up.
In any case, I do hope my success continues on and I start seeing my C. Woltereckae get berried. The pregnant one that I had when my batch came in dropped her eggs during her 4th day in my tank. She lost them slowly, one by one. They were still nice and dark colored, so I don't think they were ready to hatch. I don't see walking baby C. Woltereckae either, so I'm concluding that the water parameter change from 7.4-7.6 (their water in the baggie they came in) to my water (which was 7.8 at the time and went up to 8.0 over the course of 2 days and is now stable at 8.0) made her drop em to acclimate to new parameters.
And... that is all. Pics later tonight~~~
