shrimplet survivalrate less then 10%

[nuri]

Goodafternoon fellow shrimplovers

 

I need some advice to get my shrimplet survivalrate up

 

the tank had been recycled for 4 weeks and is running now for about 7 months.

substrate: akadama

it is a 50 L tank with 15 spotted heads + 2 taiwan bees in it ( to keep taiwan bee blood line in the group)

 

 

i feed:

 

dennerle shrimpking complete every 3 days

bacter ae everyday

CSF zemelenpouder  everyday or 2

csf nettle sticks 

some more products (forgot the name)

 

have catappa leaves in it 

 

i do every 2 weeks waterchange of estimated 20%

 

i use reversed osmose of 250 microsiemens (us) for waterchange and the aquariumwater is 290 us.

 

waterparameters:

 

NO3 = 0

NO2 = 0

GH = between 4 and 5

KH = 1,5

PH = 6

chlorine = 0

PO4 = 0 (it didnt turn blue)

 

the shrimplets first died in the first weeks then i changed the food diet now they dissapear when they are around 1 month old.

 

the temperature was 25 degrees i have lowered it down to 21 degrees since last week.

May seem like an obvious answer, but what kind of shrimp?

[nuri]

15 spotted heads and 2 taiwan bee's

(Caridina)

I had tons of zebra pinto shrimplets unfortunetly they all died....

All taiwan bee shrimolets die, i havent even raised 1 to mature in thus tank.

I do have couple almost mature crystal red smily raised up but thats it...

[Soothing Shrimp]

My card tanks had deaths until "seasoned."  Took about a year.  I have no idea why, but after that things slowly got better.

 

But I now use ae to help build biofilm.  Don't know if that makes a difference or not.

[nuri]

How do you use bacter ae?

I hate that product i have to get some water in a small bucket mix it and then pour it back in the tank with the filter off.

If i put it direct in the aqua it stays on the surface

[Soothing Shrimp]

Well, I kinda cheat. LOL  I dip a bamboo skewer in the water, dip it in the ae, then swirl the stick in the water.  I do this every feeding.

 

What floats usually falls down rather quickly for me.

Seems like a lot of food for so few shrimps. I feed less than that, and less frequently, for a 10 gallon with probably close to a couple hundred shrimp.

 

Also, what are you using to test your nitrates? And how are you remineralizing your RO water? I am not sure how to convert your µS to TDS.

 

Are you dripping in your water changes?

[Soothing Shrimp]

Good catch on the food Sarah!

[Purplepanda]

I hate that product 

 thats's odd, it's surely one of the most popular foods around and is excellent for TB young.

 

a quick stir on the surface usually sinks most of it, my shrimp also grab it from the surface..

I think the two most important aspects to a shrimplets survival is oxygenated water and food. Food not meaning drop in a pellet and hope they eat, but being able to deliver the food to a place where the shrimplet feels confident enough to eat and not be crushed by adults. That is our challenge, I started a couple months ago using Lowkeys Double Speed to pinpoint food distribution with a pipette. Seems to have helped get the food to where it needs to be, but the most important piece I added was a Choice Bubbler that helped increased oxygenation within my water.

[adrand]

Adding extra oxygenation made a HUGE difference for baby shrimp survival in my tiger tank. And I mean huge difference. In a 20 long i had only a sponge filter with very few babies surviving, probably around 10% like you. I added a large airstone and i saw a large uptick in the amount of babies around the tank. Id suggest adding an airstone or something else to add oxygenation.

[nuri]

airstone does not add oxygen it helps the gas exchange on the surface, to have a better benefit i use oxydator restocked with 6% H₂O_{2 .} 

 

i want to thank all you guys for the effort.

 

have you guys had the feeling that all baby shrimps were dead but 1 month later they show up....... that is prety much what happened to me today i turn the light up and i see a prety grown up pinto zebra between the moss.

 

he must have a good hidingspot lol

 

i reminilaze RO from 4 tds till 160 and my tank is 184 tds

 

i dont over feed right? atleast i am not noticing it....

 

everyday baxter ae 

every 2 or 3 days a pellet of food 

every 2 or 3 days small bit of CSF zemelenpouder (babyfood)

 

oh yeah btw: i have also roughly 20 neo's grown up in it (came as a shrimplet with the moss when i transfered it to this tank)

[nuri]

that is the main scedule of feeding sometimes i change to an another (baby)food product or mix it

[Pokeshrimp]

How much bactor ae are you feeding? Maybe its just me but when i first started using bactor ae i easily used too much. I started using the skewer technique and the tanks seem to be doing better. I also try to dip the skewer where all the babies hang out or in piles of moss where there may be hiding babies.

[nuri]

it is a 50 or 60 L tank and i dose between 1/2 to 1/4 of the spoon.

 

overfeeding bacter ae cant harm the conditions right?

[Soothing Shrimp]

Nits zoom up according to poopians calcs when using the suggested dosage.  That's why some people, like me, have cut back on dosing to the skewer.

[Vpier]

1/2 to much.

Using the recommended dosage that is printed on the jar is a bad thing. I Learned the hard way and struggled with maintaining proper water parameters, nasty things like hydra and planaria enjoyed it. I now use a little bit once a week and no more nitrate, tds and nasty creature problems. I dissolve AE in a glass and use a 12 inch long pipette to spot dose where I think babies might be hanging out.

Thanks nuri for the info, I stand corrected of airstone vs gas exchange vs oxygen. I love learning new things. In the end though, for me the addition of the airstone made a very noticeable increase in the survival of babies.

[Clansman]

I agree with targeted feeding of fine baby foods, I use a 20 ml syringe that got a 12 inch hard plastic 4 mm tube I spread it to all the common areas glass dish almond leafs etc, Oxygen is also another I agree on, but there's another to consider does the soil have a build up of bad bacteria for babies graze on the soil from about 10 days and with lots of moulting I believe there vunerable , I have upped my use of beemax and increased water changes with matched water my survival is great

[nuri]

what for feed recommandations do you guys use  for bacter ae ?
