Shrimp death.

Recommended Posts

Shelly_shells

Hi. I don't know where to go to to ask this question. I've had my shrimp tank for a few months now, and I had four cherry red and four crystal red shrimp adults in my tank. I found one of my cherry red shrimp had died during the night. It looked as though it had cracked behind its head, like when they molt.

What would have caused this?

He was a big shrimp and he was an adult when I purchased him.

One of my female red cherries has a belly full of eggs. This lot of eggs seems to be a huge amount compared to her unsuccessful few attempts of carrying eggs in the past few months. How can I help her keep them this time?

Is the death going to affect her?

Thanks everyone.

Do you have any info on your water parameters?

This will help work out what is going on.

Definitely sounds like a death during a moult, as BF said, we need to start from the beginning & your water parameters are vital for us to help, so as much info as possible, PH, KH, GH, temp, TDS, Nitrate, Nitrite & Ammonia will be a great start. Depending on your WP, the death itself shouldn't effect the berried mamma but the cause of the death might.

These are my results from today.

Ph 7

Ammonia 0

Nitrite 0

Nitrate 0

Temp 24

I have a 23 litre fluval tank

10% water change was done less than a week ago

I use tap water with conditioner during water changes

I replaced the filter media as well.

I'm using API freshwater master test kit by the way

They look ok, did you change all the media when you did the water change?

Why do they die during a molt? How can I, if possible, prevent it from happening again?

Yes, sponge, carbon and biomax

You should have KH & GH in that kit too, can you test those for us as well?

Yes' date=' sponge, carbon and biomax[/quote']

I wouldn't replace all the media as once as you need to keep some of the bacteria to seen the new media, next time only replace one at a time.

Shrimps have a lifespan of around 1.5 years ish. You got it as an adult so there is a chance it might of died from old age.just something to think about. I never buy adult shrimps even if it's cheap coz sometime they only have a few months to live.

My test kit just has ph, high range ph, ammonia, nitrite, nitrate. Do I need to get other tests?

I thought the API master kit had GH & KH in it? These two(general hardness & carbonate hardness) are very important to shrimp & make a major difference to moulting.

Nar, the API master kit doesn't have GH or KH. Well not the one I bought anyway.

Definitely worth investing or go to a LFS and get your GH & KH tested.... Sounds like a GH or age related issue.

I also got some mystery dead today...5 already :(. Unknown dead, they are all the same as Shelly, have a cracked behind its head. My GH is 5-6, KH 1, the rest of WP is good, also just instal the UV sterilizer.

A high GH would have caused this...I had the same problem just yesterday with my crystal only the head part moulted, the bottom half looked like it was going to leave it's head (almost decapitation the poor thing) it died as well. I checked my GH and it was around 10 and TDS >350 which is way too high for crystals? I really don't know what made it go that high maybe wasn't thinking when adding the mineral powder or shrimp salts and added too much! slowly dropped it down with RO water

Ya, high GH cause that. But in mine, GH only 5-6 which is good, TDS 150 (not too high) and still dont understand. :(

I'm curious to know what your Ca:Mg ration is ..... any chance you guys have a Ca Test kit ? Or go to the local LFS to test ?

Unfortunately I dont have Ca test kit. What is it about? I think that kit is for salt water?

Magnesium is the key to unlocking Calcium Carbonates potential. It is able to make Calcium absorbable in shrimps bodies. Without it they would suffer from lack of calcium. It is needed for a healthy calcium absorbtion and balance as well as healthy muscles and nervous system.

Does salty shrimp mix for water change contain the right amount of magnesium for calcium or do I have to add extra magnesium to salty shrimp mix?

I'm sticking with just Salty Shrimp for now. The Mad Scientist stuff is too scary for me just yet.

Pretty sure the ratio for salty shrimp is correct' date=' but Calcium does deplete, so it's usually calcium that needs to be added.....I ONLY check my ratio's 1-2 a year, and usually only require a pinch for my 200lt tank....the 500g bag of MgS04 will last me for 167 years. LOL

Yes, totally agree, it's ONLY really once you get unexplained deaths, and the "not knowing" really bugs you, then you should start experimenting... bhahahahahaha

      Mine is a DIY Chiller, as you know a peltier has a hot side and cold side, for the cold side to stay cold, the hot side must be kept cold and with a heatsink and fan to cool it down. My DIY chiller has two sides and two water block. blue aluminum block with tube leading to the outlet of the canister filter and back to the tank to chill the tank water. copper block is to cool the hot side of the peltier, with copper block to the radiator/fan and a water pump looping. The problem is the tube from the water pump came off, apparently the plastic from the pump started to melt and the tube came off and the looping side had no water, so the copper water block stayed hot all the time with heat transferred to the cold side of the peltier also heating the water. since the copper takes time to cool down, most of the heat and the room hot temp had already heat the tank water to about 45 C.

      Try testing it again and see what you get or to confirm that the previous were right, especially the higher Ph reading is all I can recommend! If there is some explanation for the difference hopefully someone will reply and let you know, but I expect there won't actually be a difference if you do it again? Simon

      No that's not normal. But I don't know which tube in your loop had come off. Can you show us?   Yes that would have helped a bit, and at least give KMS more time to have found the issue by turning off the chiller. As I understand, kms has a peltier style chiller, and a tube of the pump had come off, which meant that hot water from the hot side of the peltier flowed back into the tank. So if the chiller was on the same temp controller, it would have turned off the chiller at around 26degC. The tank might have got warmer in his room, but it would have been at a much slower rate, and certainly would not have reached 45degC.

      I'm using the API master test kit with the dropper bottles. I was just very confused at how much more akaline the water was coming out of the filter compared to the water out in the open. I can't imagine how this fluctuating change in pH is going to be beneficial for my crs.
    • sdlTBfanUK
      What type of test are you doing strip or drip? I use drip tests and always ignore the first attempt as no matter how well I clean and keep the test set it is often way out of line. Las time first test was Ph8, second test Ph6. Sometimes first attempt looks ok so I have no idea what is going on????? If you just tried once it may be worth testing again? Simon
