Failed Molt Treatment?


Recommended Posts

Chels

I finally bought some new yellows for my picky females who won't breed with the males I have. Of course I also had to buy some fires for my females too, and a couple of blues + pumpkins since they had some. 😅 It seems I always get so many more females than males, so I had to even out the numbers more.

One of the fires I bought had that light line down its back, meaning it was just about to moult. I was hoping acclimating & moving to a new tank would trigger the water parameter change it needed, but apparently I was wrong and it died overnight. Sucks. 

This made me wonder if there isn't a way to treat a shrimp who has a failed moult happen and triage to save it? With birds who are egg bound you give them liquid calcium to immediately fix the issue & save their life. Is a failed moult a calcium deficiency? Or maybe all nutrient deficiency? So potentially triaging them with nutrient-rich water would stop the problem? Maybe putting them in a quarantine tank and add a drip line with blackwater.. I may be totally off but there should be some last-minute fix for once you notice the signs (the light-colored line, hiding for a molt, struggling/wriggling but no moult detaching). 

It never happens in my tank, but whenever I purchase new shrimp there's a chance one or more will be right in the middle of their moult. I am always buying new shrimp these days so I want to have some way to stop it.

I'm not sure there woud be much you could do in that situation, hopefully someone else may have some ideas! The stress of the moving added to the waater change and  the mout is likey to be too much all in one go! Even without the obvious moult I woudn't personally expect all the shrimp to survive and usually a few disappear/die in the first 2 weeks! If you got them from a shop they have already beeen through a lot going from the breeders tank, transit, into shop tank (different water probaly), transit, into your tank (again new water) at the very least, there could even be another wholesaler to add to that? I always used to buy direct from hobbyist (ebay) which meant just going from their tank, transit (post), to my tank, but even then I usually lost a few in the first 2 weeks.

I did once see a youtube video where someoone helped a shrimp moult by using tweezers but that is very fiddly, you would need to fish the shrimp out and put it into a smaller container, and it likely still wouldn't work, even if the shell were removed it may die in the next few days from stress.........

If you try anything please let us know how it goes! Hopefully some others will have some ideas?

On the ratio issue, most people would prefer more females to males as you only need the one male to breed with the females and you will get more baby shrimp the more females you have! There is probably another issue if they aren't breeding and you have both sexes?

Failed moults are usually associated to Calcium content in the water. That is, your GH reading.

Too much GH and the shells (and eggs) become too hard and moulting becomes difficult. The shrimp looses too much energy trying to moult. Too little and their shells don't develop properly causing deformities (maybe GH under 2).

This is a long term affect, that is, if you see it, it's already too late and nothing you can do to help a shrimp that is having issues right now.

Thank you so much Simon & JayC!!!! Super insightful and helpful as always. 😁 I wonder if there's something I could use in a quarantine tank that would help soften their shells and stop a failed moult in its tracks. There are plenty of liquid calcium products out there, but none I know of to lower the calcium.. 

Mostly I wanted more yellow males since a female I've had for nearly a year now has refused to breed with the blue dream, painted fire and pumpkin males I've had. She's a picky girl!! I have plenty of yellow males now for her to choose from. 🤞🤞🤞 The rest are not picky at all. 😅

That "product" is called RO or Rain water. 👍

Would it be safe to put a shrimp into RO/Rainwater if it was struggling with a molt, as the parameters would be way off, or is it ok for a short while in that water?

I didn't mean "just dump the shrimp into pure RO water" by the way.

I guess I was referring to introducing the shrimp into a quarantine tank with RO water that has been treated with less remineralisers, so the water is more on the soft side, ie anything 100 TDS or less.

Dilute the Calcium in a tank (ie. GH) with RO or rain water.

OK, got it!

I would think though that that whole process may kill the shrimp from the extra stress combined with the fact it is already having a problem and probably stressed?

It is worth knowing thoughas an option!

Thanks JayC

Exactly, it's only an option.

Do nothing, and the shrimp will die trying to moult. So I guess trying something is better than nothing at all.

      Hi Crabby, I’ve been popping in and out quite often and answered a few questions here and there .  Im glad to have been of so assistance to fellow shrimp keepers over the years.  It’s a bit sad to see the forum so quiet. We were a very active and friendly bunch over the years. Helping each other out, giving away shrimp to new members who showed interest. Even playing games between us and generally having fun while learning about our new hobby. As to my tank the reason I queried about the spike of ammonia is mainly because if you play with substrate , move it around etc you can cause a small spike. As my substrate had been outside for quite some time I fully expected it to take a week or so to go through a mini cycle. I’m pleasantly surprised that it still isn’t showing any change just the tiniest bit of nitrate so tomorrow i will catch out 20 culls I have in my pond outside and see how they go. I need a reasonable number because it’s a big tank - if I only put 1 or 2 in I might never see them. I’m wanting to put all my black pinto, galaxy and Taitibees into the tank plus some Blue Bolts and Steel Blues. I will also put my Bloody Mary’s in for a contrasting colour. I only have 3 tanks now so it’s a bit hard to do proper selective breeding but as all my shrimp are hybrids it doesn’t really matter about mixing them. That leaves a tank for my Red pintos and Taitibees and a tank for fancy Tiger patterns and Blue Diamonds. That should keep me happy again.🥰

      Hi Ineke! I must say, I was pretty surprised to see a post from you, it’s always pretty interesting to see a past member come back to the forum. Some of your posts were really helpful to me when I was getting started with shrimp, so thanks!   I think I would personally wait a week to be sure, but to be honest, I can’t see any reason for an ammonia spike. If the substrate has already run for 4 months, and you have 4 fully cycled filters, I reckon you should be fine. Definitely go culls first though.

      I uderstand your concern, it is concerning! You are probably just going to have to ride this out, as JayC, add another filter and bacteria, the bacteria you will just have to buy what the shop has and give that ago? Do as thorough vac as you can, moving things out of the way where you can. Keep up with water changes as well as that will reduce the ammonia etc, but add new water slowly. Simon

      Thanks Simon . I just needed someone else’s thoughts. I will pop a few culls in over the weekend if the ammonia hasn’t spiked. Better to be over cautious than sorry. It just didn’t seem right that there was no spike but I guess 2 large canisters full of bacteria are a big help too. I will let you know how the culls go after the weekend.  As you say sometimes things just go right but not very often when you have TB type shrimp involved 😳 No not really I’ve been very lucky over the years with no actual disasters with my shrimp.

      I would thnk everything is ok as the sustrate was used and passed the point it may cause a spike, but just check it for a week (occassionally ammonia/nitrite/nitrate, you could leave it for the week but I would prefer the extra peace of mind you will have from more frequent testing for this week) and try some culls now to be on the safe side! Using the old water will have helped, undoubtedly! There doesn't sound like anything mentioned would cause anything other than what you have seen, but I understand your concern, rarely does everything go so well in this hobby, but with your years of experience and from your post all looks great - I will however keep my fingers crossed................ It is always great to have past members return and hear how it is going? I have read many of your old posts with interest. Simon
