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 :).
Hydra and shrimplets?
VaultBoy posted a topic in General Questions/DiscussionsHi everyone, I have a bit of a problem (i think...) I seem to have added freshwater hydra into my tank somehow and have noticed massive population increase at the same time as I have had blue dreams, tb, pinto and crs mischlings all release babies. For a bit of perspective, the tank is only about 3 months old but was started with mature substrate and filter media so I could cycle it more quickly as I had to get my shrimp in there asap. I am new to keeping all of the variants in this tank but have kept an RCS colony for 3-4 years so wanted to try new things in a shrimp only tank. So my questions are... Do I actually have a problem? Are the hydra going to eat the babies? If they are a problem then how do I get rid of them? I dont want to introduce any fish, cant really remove all shrimp/shrimplets to heat the water enough to kill them and I dont think there are any shrimp safe medicated solutions... Please help me!
riffles eating shrimplets?
waffle posted a topic in Australatya striolataPeeps who keep riffles, do you find they prey a lot on shrimplets from other species? I'm thinking they'd eat larval-form babies that float into their fan-hands, but wondering, do they hunt around for non-larval shrimplets? I'm trying to decide whether to continue keeping them in their own dedicated tank or whether they can find a home with my yellow cherry tank, which is currently very understocked. I keep them out of my dedicated native tank because I don't want all the larval paratya to be eaten. I think they'd look quite nice together with the yellow cherries, but I'm leaning towards that being a bad idea for the sake of shrimplets.
Matuva posted a topic in Australian Caridina spp.That's a question I'm always wondering about: do the typus hatch juveniles like Neo, or do they release larvaes (Zoe) which would need brakish water to develop?
Chlorella Powder for newly hached shrimplets?
Aquathumb posted a topic in Food & NutritionThinking of using organic Chlorella powder to feed new born shrimplets. The powder is very very fine and would defiantly be manageable for the littlest of shrimp. My only concern is that it will foul the water faster then my current baby food, Biozyme so care would be needed not to over feed. Thoughts?
Disciple posted a topic in Shrimp Health & CareI just found my first set of shrimplets and it is very exciting (just after my son had his 3rd birthday) My question is what is the process from here? I have been feeding once every two days but have been rotating between pea's, shrimp snow, fish flakes and algae wafers. Thanks in advance. Man i thought I was staring at my tank too much before I think I'll be up all night straining away now.
