      Am curious to know what ferts people here are using, are you using estimated index, dry ferts or are you using liquid ferts, if so what exactly are you using? ADA, API, AquaGreen, Excel?

      Hi Jayc, I use Sera liquid test kits for most parameters except ammonia. For ammonia I use the traditional API liquid kit just because I haven't bought a Sera one yet.    Yes, I think so. That one was a wine red so it was quite dark. The photo was taken about 30 mins after it died and I know it seems blotchy but I think that might be the flash on the camera as to the naked eye the colour seemed solid. All the tanks were set up around the same time. The tang tank is now about 15 months old, the CRS about 13 months and the blue bolt etc about 11 months old. The substrate is all out of the same bag. They were all started with SeaChem Stability, then cycled for a couple of weeks until water tests revealed that they were cycled and ready to go.

      Hi Simon, Thanks for your reply. I really hope you guys can help me, and more importantly, my shrimpies. Yes, they are in the same room right next to each other. It's my shrimp room - neos on one side, caridinas on the other. I live in a really hot place so run a/c most of the year. Here's a picture of my 3 caridina tanks having a water change. The CRS tank is closest to the camera. Yes, in the 'problem' tank there were, until last Tuesday, 2 pieces of charcoal bamboo. I wondered if they might have been causing the problem so I've taken them out now. The only other difference is that that tank has a sponge filter and a pat mini as I didn't think there was enough circulation and that may have been causing the problems. It's been running for about 6 weeks and was new when it went in. I've got it on a very low setting though as they can be a bit rough especially on shrimplets. The vegetables are always certified organic and I grow my own IAL (I live in the tropics) and mulberry. Cholla and alder cones are purchased but they go into all the tanks (including my neos which are breeding like mad). Do you think it might have been the charcoal bamboo? Cheers

      How are you measuring pH that low? PH meter or liquid test kit? And is that colour normal on the shrimp pictured above? You said, this problem tank is about a year old. How old are your other tanks?

      Sorry to hear you are having a problem with one tank. Regarding the breeding stopping, that may be as it is winter with the taiwan bee shrimp where you are so I wouldn't worry about that unduly unless it carries on after winter? It onl seems to happen with Taiwan bees and I had this happen and have seen you tube videos and heard it happens with others (not everyone though oddly). The main problem tank, I can't see anything that looks a problem at first glance and as you are running other tanks the same way it must be something specific to the tank. Are all the tanks kept together in the same area? Have you put anything wood/new etc new in the tank that may have been contaminated with pesticides that is slowly poisoning the tank etc? Anything you can list as tank specific may help give us a clue. Are the vegetables you feed ORGANIC (though if you use the same for all the tanks it is unlikely to be that)? The simptoms do sound as though it may be some kind of toxic poisoning! The picture is a lovely shrimp and I can't see anything obviously wrong with it. I had a similar experience with my last shrimp tank so I know how frustrating it can be to pin point the problem! Simon

      For about 2 months now I've been losing one or two of my CRS every day. Tank has been running for about a year and initially everything was normal and they were breeding well. Then I started noticing the odd unexplained death, then it became more frequent, now it's every day. Parameters are: pH 5.5, GH 4, KH 0-1, Ammonia 0, Nitrite 0, Nitrate 5, TDS 120 Temp 22C. What's left of the colony are fed 2 - 3 times a week on a variety of quality foods including blanched zucchini, blanched mulberry leaves, HWA bacterium, frozen bloodworm and a few foods I've bought from breeders who make their own. They only get a tiny amount and it's usually gone within a couple of hours. Tank maintenance includes once weekly 10% water changes and the water I use is rainwater that I run through the RO and remineralised with GH+ liquid. I have two other caridina tanks - one with tang tigers who are breeding like mad. I never have deaths in that tank and it's got almost the same parameters just the GH is 5 instead of 4. The other tank is for blue bolts, mosuras, pandas and shadow pandas. I don't lose any shrimp in that tank either, BUT they aren't breeding. I think I'll have to start another thread for that issue though. I'm careful to clean any equipment used in one tank before I use it in another so that I'm not cross-contaminating. The shrimp seem perfectly normal until they fall over and die. They did stop breeding a couple of months ago so my colony is getting smaller by the day. The tank has the usual shrimpy stuff - IAL, alder cones, cholla wood. Substrate is Amazonia II. Below is a photo of one of today's victims. I have a video of it in the throes of dying too, but can't seem to upload it. It just shows the shrimp on its back and its little legs kind of spasming. Is anyone able give me any idea what my shrimp are succumbing to? Muscular necrosis perhaps? Thanks in advance.
