Roborep1 Posted November 2, 2019 Report Share Posted November 2, 2019 Hey Gang, I have been keeping CRS shrimp for 5 years. The current tank has been running for awhile. Everything is very stable water wise. I use some kind of volcanic substrate. I don’t recall the brand. Plants and floaters. It’s a small eheim 6g I have run the eheim filter and I have run a sponge from time to time. Lately it’s been sponge 1+ year. I top with RO/DI Gh 5Kh 0Ph under 6Tds 108 Temp 74 Zero nitrates I rarely see breeding and when I started in shrimp my first year it happened all the time. I lose shrimp over time. If I start with a dozen in a year I will have 3-4. It’s never on intro it’s slow over time. I thought lack of breeding was due to no males so I introduced some shrimp. I had a breeding and have all king Kong’s and blue bolts at this time. While they have grown I know I am losing shrimp here and there. I am wondering if my issue is either Ph related or not enough TDS. I have always kept it low around 100 or so. I brought it up to 150 recently. Thoughts?

Roborep1 Posted November 10, 2019 Author Report Share Posted November 10, 2019 Anyone have any ideas what Might be causing my shrimp decline? Quote Link to comment Share on other sites More sharing options...
JSak Posted November 11, 2019 Report Share Posted November 11, 2019 Hi Roborep! I'll try to throw out some ideas, but it sounds like you're doing everything right and that you're knowledgeable about shrimp keeping. Is there anything you can think of that you changed in the tank from when you had success with breeding when you first started keeping shrimp until you noticed that they weren't breeding and slowly starting to die off? Also, I'm not familiar or experienced with using that kind of substrate for my shrimp, but is it an active substrate that buffers the water? If the water isn't being buffered that may be the cause of the lack of breeding as there may be fluctuations throughout the day in pH. The fact that your shrimp are surviving and living for quite a while without breeding makes me think that there's something in your tank that's slightly off that's causing stress to the shrimp. Not enough stress that it's causing significant die off, but enough stress to be preventing your shrimp from breeding. The parameters look good to me so I'm not sure if there's anything there that might be causing the problems. Saddleback Shrimp 1 Quote Link to comment Share on other sites More sharing options...
rhoagland Posted November 11, 2019 Report Share Posted November 11, 2019 How often do you do water changes? What remineralizer do you use? Quote Link to comment Share on other sites More sharing options...
JT_Redmist Posted November 11, 2019 Report Share Posted November 11, 2019 Hi Roborep, Your parameters seem to be in check. I'm not sure what kind of substrate you're using, but how long has it been since you changed it last? I've had some instances where I would lose shrimps, and all my param were in check. I simply did a tank reset, and that cured the issue. I know it doesn't answer your question, but that's what worked for me.
