TL;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.
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
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 :).
I have 18 shrimp in a 90l tank. They have never shown much interest in any food I give them. I give them a pinch of spirulina every 3 days and three or four pellets of JBL Novo Prawn.
I've tried blanched vegetables, hibiscus flowers etc and the ignore them all. Dies this mean they have enough biofilm?
I have thousands of detritus worms, including some which are swimming about in the water column, which would suggest I am overfeeding, though this seems hard to imagine with the tiny amount I am putting in.
A couple of RCS females are berried so I am reluctant to give up the spirulina as I don't want the shrimplets to lack food when they arrive.
Hi all. I'm a newbie. I'm keeping a 90 litre tank with cherry shrimp and daphnia together. I'm feeding them spirulina and commercial shrimp food.
Does anyone know what else I should be feeding them? Anyone else have this mix of tankmates?
Thanks to the guys at Shrimp Love Mulberry i recently received a pack of the new Mulberry based shrimp food.
The pack contained 4 syringes of mulberry shrimp food and an instruction card for storage and feeding. Nothing to complicated there, just store the syringe you are using in the fridge and the spare ones in the freezer. Great being able to freeze the syringe and all as you know it is not going to go off so you can order enough for 6 months or more and that will save on shipping costs.
So like with any new aquarium product i headed straight to the shrimp tank to give it a go. My thinking at the time was that the product would be a bit like Repashy but softer so it could be easily syringed. My tank has a good flow in it so it is always a bit hit and miss dropping food from the surface to the feeding bowl, like wafers or crack, but i'm getting pretty good at hitting the mark. I held the syringe at about the right point to get the bowl and gave it a little squeeze. This is not how you do it...Lol
The product came out in a nice tube about 2-3mm wide, like a soft bit of crack, and then hit the flow of water. It then turned into a snow of mulberry goodness as it fell through the water column and was evenly distributed throughout the entire tank. This is not a problem for giving the shrimp a general feed, providing you dont over feed, but there was now no way i could see if the shrimp were attracted to it specifically so i could give it a subjective review. The shrimp got excited as they knew there was food somewhere in the tank but i think it took 10sec for every shrimp in the tank to find some of it and settle down for a munch.
A few days later it went a lot better.
Getting the hands wet i put a bit into the feeding bowl and sat back with the camera ready. My display tank has a mix of RCS, Native WA Glassies and a few Pygmy Cories. I have found that the Palamonties Australis are more of a carnivore than RCS and will rather eat live black worms than actual shrimp food. Fortunately, or unfortunately for a review, the much larger glass shrimp got into the food bowl first and the RCS were kept at bay until it had it's fill. I had put in about enough food for a normal 3-4 day feed and it was gone in about 2 hours. My normal harder food last about 6-8 hours for the same amount.
Future feeds will be done from the surface again as i dont over feed and the distribution in the tank ensures all the shrimp, even the new ones, dont get muscled out.
Hello, just wanted to show another food source I grow for my shrimp and snails.
Just how it looks, a plastic tub filled that gets lots of direct sun, I usually fill it with old water from my planted tanks to help the process.
Its a bit full ATM lol but there's a second tub underneath for extra strength.
I just grab a small pinch and put it straight in my shrimp tanks, they all go nuts for it.
Alternatively you could remove excess water then dehydrate it on baking paper to make a dry feed.
An hour or 2 later:
