Cherry shrimp death and hydra outbreak - help please.
Shrimps&Frogs posted a topic in Shrimp Health & CareTL;DR - I had a shrimp become paralysed and die with no obvious red flags and stable water parameters. I found about 10 hydra and would like to know if I can treat with LCA Planaria Fix without harming my shrimp, particularly my berried shrimp and new shrimplets. Hi everyone, First, let me say thanks to everyone for all the info on this site, especially Jayc and sdITBfanUK for your many years of patient advice, you've already helped me more than you know! I am a new blue cherry shrimp keeper and everything had been going pretty great for me shrimp-wise. I have a 41L/9 imperial Gallon tank which I cycled/matured for about 6 weeks before adding shrimp (the tank cycled in 2 weeks, but I left it a bit longer). I then got 11 blue cherry shrimp 7 weeks ago and as I said, everything had been going pretty well. 5 of my females matured and berried with what looks like a lot of eggs, and the shrimp always seemed happy and normal. About 1.5 weeks ago I found 1 dead male shrimp which looked almost stuck in the substrate at the back of my tank. It had turned white/pinkish by the time I found it and I have no idea how long it took for me to find. I wrote it off as everything else seemed fine. Then 2 days ago I saw what looked to be Scutariella on a few of my shrimp, including 2 of the pregnant ones. There was 1-3 little white things sticking up from their noses that seemed to move independently. So I salt dipped the affected shrimp, which cleared the obvious white things and the shrimp all seemed normal. Then yesterday I found a shed with some eggs still attached to it. I believe they were from my first female to become berried due to their colour, she had been berried for about 4 weeks. I thought that it may be from the salt dip. Things got worse that evening when I found one of my shrimp upside down, apparently dead. I went to get it out of the tank and it attempted to swim around before falling back to the substrate. It looked as though its body was paralysed, but its extremities could still move. It otherwise appeared fine, and had nothing obviously wrong with it. I put it in a small container with clean, prime-treated water as I had read of some people having a similar thing happen due to either toxicity or lack of oxygen. I also topped up the tank and threw in a small sponge filter to increase aeration in case (I don't think it was that as all the other shrimp and snails were acting normally). The afflicted shrimp's movements decreased until I thought it was dead, then about 1 hour later it appeared to be increasing its movements and even flexed its tail a few times but then movement decreased again and it actually died. My tank parameters have been stable the whole time my shrimp have been in there, and I was wracking my brain trying to work out what could possibly have happened. Tonight I found about 10 tiny hydra in my tank and I am wondering if there is a possibility that the dead shrimp could have been stung by a hydra? Especially if she had just moulted? She may have been the one that lost the eggs, but there is another shrimp with similar markings that I have seen wandering around with no saddle, and as all my females have been either berried or saddled the last week or so, I thought that that one was probably the female that shed her eggs. There were some other moults as well though. My tank parameters are: Ammonia and Nitrite: 0 Nitrate: 5-10ppm (this is what they are constantly, and I struggle to tell the two apart, if anything the colour was a little lighter) Temp: 22 celsius Ph: 7.2 Gh: 8 Kh: 3 TDS: 210 Phosphate: 0.25 I use a thermometer, TDS and a Ph metre, salifert phosphate test kit and API liquid test kits for everything else. I have been doing about 20% water changes once a week and slow drip the freshwater in. I use tap water (and this is what the shrimp were raised in) treated with prime. I have plants, driftwood, dragon stone, Indian almond leaf and a small piece of cuttlebone. These things have all been consistent since the beginning (I added the cuttle bone after cycling to slightly increase my Ph and its been very stable since. I use LCA shrimp safe all-in-one fertiliser at about .75 of the recommended low light dose twice per week, Seachem advance, and 1/8tsp LCA potassium sulphate added at water change. I was due to change water today, so I do not think it is that. All the other shrimp seem happy and normal. I did rearrange the tank about 2 weeks ago and got rid of some Vals that were spreading everywhere and looking scraggly and added a couple of new plants. There has been a bladder snail boom over the last week or so and brown dust and a little green spot algae on the glass. I have been having issues with getting the plants to grow nicely, but there is still a decent amount of growth. I should also mention that I get chemical triggered migraines and so there are no spray chemicals of any kind in the house, and am extremely careful of scented products and any chemical use, so I don't think anything could have gotten into the tank. I have kept frogs (who are very sensitive to chemicals) for 8 years with no mishaps. In good news, my first shrimplets were born today, I have seen at least two :), so it has been a roller coaster! I have some LCA Planaria fix as I found one hydra (bigger than the current ones) just before adding my shrimp. However, after removing that one I could not find any trace of more despite daily careful checking, so I held off on treating. Would it be ok to use that now? I can't seem to find what the actual ingredients are. I am worried about hurting the shrimplets and the berried shrimp, but obviously hydra are a danger to them as well. Please help :). I think I put in all the necessary info, sorry for the long post, thanks for sticking with it if you kept reading :).
Constant red cherry shrimp deaths
bristlenose posted a topic in Shrimp Health & CareHi, I've kept Red cherry shrimp for at least 3 years. I've never had a problem with them. I used to keep my shrimp in 500l tank but i got careless while buying plants and introduced planaria into my aquarium. I only noticed after the numbers got out of hand and i noticed the shrimp deaths adding up. I moved 200-300 shrimp into a standard 4ft tank planted aquarium and dosed with noplanaria along with melafix to ward off any bacterial infections. There were multiple dozens of shrimp shells all over after being moved. Initially i believed it may have been the planaria/bacterial/constant water changes/stress of new environment(i drip acclimated them for a 5 hours) that was killing them but i haven't changed the water in a 2 months but i still get the occasional death, 1 or 2 every few days. There are decent amounts of cuttlebone in the filter and also in the aquarium itself, and i also feed them the occasional powdered egg shells but i still get molting problems. Adults and also the month olds are dying, no discrimination. They're fed every other day shrimp snow, high protein discus granules and zucchini/pumpkin/spinach/dry seaweed every 3-4 days. I can see many berried females and small shrimp and also babies but i'm still losing shrimp constantly, easily 80+ in total. I don't want to buy a gh/kh test, they have never had any problems with molting in their last aquarium so can't quite understand why they're having problems now in the 150l. I've read so much online but i can't seem to find an answer, i'd sincerely appreciate any advice i can get. Thank you so much if you've managed to read all of this. Please feel free to ask any questions. The photo is from the current setup they're in. Previous tank parameters: Ammonia: 0 nitrite: 0 nitrates: 20ppm Ph: 8 substrate: sand Lighting: generic LED lights i got off ebay I don't know any other parameters. cuttlebone in the tank and filter, no ferts, heavily infested with guppy grass. Large colony of bristlenose. New tank parameters: ammonia: 0 Nitrite: 0 Nitrates:30-40ppm co2: 3-4 bps Ph: 6.5 Lighting: generic LED lights i got off ebay substrate: ada aquasoil The new tank is heavily planted and dosed with root tabs and liquid ferts. Cuttlebone in the tank and filter. 6 large pieces of seiryu stone 17kg (i doubt they're authentic so they're some kind of limestone) Shrimp only tank
Taylor posted a topic in Shrimp Health & CareHi All I have got an established cherry shrimp tank with 4 assassin snails, it has four air driven sponge filters and is well planted with big bits of moss and bog wood. I bought the colony about a year and half ago and all has been well lots of young. In the last month I have lost about 20 shrimp, 3 to 4 a night! I have kept up my normal 10% water change every other week no change. so today I went to 2 different aquatic centres that stock shrimp and got them to do water a test for me. Both tests came back perfect, no reason for deaths at all! what is going on? Any help would be very apriciated, the only conclusion I have come to is too much interbreeding, as I haven't added any new shrimp for a wile. Taylor
