Hi every one, I am not exactly new, but it has been a long long time since I have been here, been working on insects and selling framed insects at a couple of Cairns markets and with the virus shut down I am out of work, so I have time to rekindle an old obsession, shrimp and aquatic critters, I can not go up cape York at the moment to look for new freshwater crab species, there is loads of new species to be found and shrimp species to. Any way I will spend more time here now. Bob. AKA northboy

Hi, I've had shrimps for quite sometime now and I've found a particular worm in one of my red cherry tanks. I'm trying to figure out what it is. I know it's not planeria. Can someone please help ID this photo? In the photo where it's yellow those are it's babies. I've already remove it and start to dose no planeria.

Ask the person u bought the "roots" from if they have been treated with any chemicals. Did you boil them first before putting into tank? Other possibility is over-feeding related water pollution

Hey bob, good to see you’re back, I’ve read through a bunch of your threads and articles during my time here on skf and it’s been really helpful. Always great to have more experienced members around. Do you still have any tanks (or ponds) running? Crabby

Yes will do. Indeed seem to be fine then slowly stopping moving just their legs movi'g a little then nothing. Some loose their colors and die too. I guess patience is the only way to see the light here...

Thanks but no ?. The substrate is new from February and I don't think it's the issue. dennerle is supposed to be a top manufacturer. I checked on Google about feedbacks from this shrimp King substrate and never saw complaints. I have used their soil before in a smaller tank and never suffered such a problem.

I think this s a leech, I have had them in the past and usually just remove them manually. Mine came into the tank on leaves I took from an outdoor pond so stopped using those. I don't think they are a problem as I only ever saw a couple and never had a mass ourbreak, but maybe that was just luck and the fact I got them out quickly! They are gross.... The no planaria may help, I also had hydra and used SL Aqua - Z1 to clear the hydra and maybe it killed any leeches as well(?), as it kills planaria! I would try just removing them as you see them if the No Planaria doesn't work and see how it goes for now. I doubt they are harmful to shrimp normally? Simon

Water parameters look to be okay from the discussions above. Have you got the ammonia test kit yet? There is a possibility that it might have been ammonia causing the deaths. If you detect nitrites, as you mentioned above, then ammonia would have been present in significant amounts to affect the shrimp. Continue water changes, regularly. Say 10% daily until you get that test kit. If your ammonia test kit detects ammonia, we will increase water changes. But stay at 10% daily for now.

it's actually grape wine wood, sorry for the confusion ... https://www.truffaut.com/racine-decorativre-pour-aquarium-pied-vigne-m-542110.html

Don't forget that your shrimp will decrease breeding in winter, which you are approaching! I would maybe change 20% water for a month and see if that makes a difference as you may still have a quantity of tap water in the tank if you are doing small changes of 10%. Not a lot of point though if you plan to reset the tank with new substrate! As you were using tap water at the start and that had a higher PH then the soil would have exhausted quicker so it may be a good idea to change the substrate. As you are using RO now the soil will buffer much longer and it looks from the last picture of the tank that there isn't too much grown in to make changing the substrate too difficult? It wound be easier to start the soil in a bucket for a month and then run the new setup for a month, this way the shrimps only need a new home for a month and maybe the CRS could go in with the bloody mary (the red cherry though???) for that time? At least if you do all that soon you will be done/set for the next breeding season! Having gone through this thread in its entirety I think the fact you started with tap water of a higher PH (admittedly only slightly) is what has caused this. Remember though, in reality it is all working pretty well and those shrimps will be used to those parameters (which aren't that bad anyway) so changing/messing will probably mean much work and loss of some shrimps, however if you are up for that, all considered I would change the substrate and because you will be using RO from the start in the long term it should pay off? You may not need to change the substrate for a long time or even ever when using RO water as the buffering won't be needed if the PH of the RO water is already perfect? Simon

I just leave them to eat whatever they can find. Basically micro organisms and biofilm.

OK thanks. No I have not received the kit yet. 8 wanted to check current parameters before doing anything. The only shrimp still alive is a taiwan bee. Supposed to be the most sensitive!
