Cant keep a shrimp alive , What am I doing wrong ?

After almost a year of running a very successful reef I wanted to add my first shrimp. I got a nice coral banded shrimp at my LFS , temp acclimated for 20-25 mins , dripped for 1h30mins , introduced with the lights off in the DT and after 2 hrs it had already lost one of its claw to what I assume either stress of maybe a aggressor that I did not see. After being very calm for 20-30 mins in a shaded area of the tank , the hermits and nasarius snails were making sandwiches out of him :sad2:

Checked my water , all was good as usual. PH/Ammo/Nitrate/Phos/Alk/Cal and Mg were all pristine like the last reading in my logs. I change water, do maintenance on Mondays and test on Tuesday. I go to the LFS on the weekend so I was thinking something may of been off. RODI still at 0PPM , even tested for Phos but it was 0.000. I then started to suspect my yellow wrasse or the hermits but since the lights were off I know the wrasse was sleeping.

2 months pass by and this weekend I got a deal on one cleaner skunk and coral banded for 40$, both very small and in good health. I pulled the trigger and as I am temp acclimating them in the DT I do a bit more research to make sure I was doing the right method. I had both specimen in a previous system with wayyy less equipment, knowledge and questionable maintenance but all was thriving and they both lived for a good year until I took down the tank. I then again temp acclimated for 30 mins , drip for 2hrs ( bumped up the time to make sure the drip was small and progressively rise the salinity to my level. Someone online mentioned that the reason of the long drip is when you do not know what salinity the shrimp was in and that most stores will run low salinity. I run 1.026, I called up the store and the system it came from was at 1.024. I took a little longer so as I was introducing them the lights were just turning on. The skunk climbed up my hand when I put it in the bag like it knew it was taking him in the tank , It stayed a bit on my hand and jumped on a rock a good minute after it got a look around. acting normal , perched upside down under a cap. I introduced the coral banded about 10 mins after and set him down in the opposite corner of the tank. he was a little more feisty so I had to take a cup with tank water and drain the bag until no water was left and I then doped him in the cup that I could put in the tank since it was all my water.

Coral banded stayed in the rockscape a bit but went in hiding and has never been seen since (4 days). The skunk cleaner on the other hand was in the other corner a little less active (30-40 mins had passed) but still walking around and grazing. I started to noticed his claws were not picking at his surrounding and it was just swaying in the waves... well it did not take long for the nasarius and hermits to smell him out and try to eat the poor guy :angryfire:

I was watching them both for the longest time to make sure nothing was getting at them but they just seem to not like my tank or water :( I cant find a explanation for this , I have 6 thriving calm fishes and many picky corals like chalices , a few SPS and a GBTA that are doing well and growing. What am I leaving out ???

Lets hear it RC , help me get my head around this! :idea:
 
I just drop my shrimp, corals, crabs... in the tank never lose anything. when I was doing all the drip acclimation process the success rate was not good. well I do dip my corals first. I am starting to think drip acclimation does more harm than good. But being the new guy I don't know for sure, just what has worked for me.

lucky guy I guess ! I do this with my cheap coral , snails and hermits but never with any fish, a expensive coral or a delicate invert like a shrimp or anemone. Thanks for the post but as the title said I want to know what I'm doing wrong or what I overlooked in the process.
 
Are you controlling the temp while drip acclimating? The bag can drop in temperature quite quickly if you aren't careful. I've drip acclimated shrimp (20-30 mins total) while ensuring the container was kept at the DT temperature and I've never had a problem.

Good point sfdan ! this is something I have not taken into account. I would have to monitor this closely next time and I will take that in mind. I should maybe try the quicker acclimation since this is the second person that states little to no drip time. maybe I overshot with the time and the bad got colder :facepalm: Or I should maybe drip acclimate and then float the bag for proper temperature before introduction.

Thanks for the input sfdan

Anyone else want to chime in on this ? :beachbum:
 
Can you float the bag in your sump while you drip acclimate? If so that will keep the temp stable.

I float for 10 minutes then start a 20-30 minute drip acclimation.
Did this on 3 sexy shrimp, 2 skunk cleaners, and 3 peppermint all of which are still around a year later. Well, I only added the peppermints maybe six months ago.

Ya know when I was in Hawaii for the first time a year ago, I saw a few clown triggerfish in the shallow beach during a particular walk. The next day at the same time, taking another walk, it happened to be raining and there were maybe five to six times as many triggerfish + others in the shallow beach.

At one point I had my ATO line running into my DT. My cleaner shrimps would continue to skim the surface right around where the fresh was dumping in. completely un-phased.

I used to think that water with different parameters would feel like acid to my critters, but with these observations I'm starting to think it's not like that at all.

I am respectful of it however and still stabalize temp and introduce water. I just do it much faster now.

Another observation is when I do water changes on my fresh water planted tank: I bring water back in over time with RO so I don't heat it. The angels love hanging around the RO water dumping in.
 
I float the bag for 10-15 minutes to match temp. Then I open the bag and remove some of the water then I start adding small quantities of water until the volume of water doubles. I pour out half into a bucket and do this one more time then I take the shrimp/crab whatever and I move it into tank discarding all water in the bag. Total time is about 30 minutes.

Essentially I do a drip method but I just stand there with a turkey baster for 20 minutes and I keep the bag hanging on the inside of the tank so the water will always be the same temp. I've never lost a fish or invert with this method.
 
Whats more then likely happening, your long drip times are causing ammonia to build up in your drip container, or your drip container is getting way to cold with those long drip times. I would shorten your drip time to no more then 30 minutes.

IMO 1.024 to 1.026 isn't that big of a jump and if it were me, I would just temp acclimate and dump them in.

This.

Drip acclimation kills.
 
Yes.. just float the bag for 10-15 minutes and then grab that sucker out and put it right into the tank..
I've always done that.. never lost anything

+1 Temp acclimate and dump.
 
Knew I was on to something!

haha yea I agree ! Seems to be a popular method... I'm off tomorrow and I will attempt to get a new one and I will try this for my own. I heard that from long shipping time the ammonia would build up in the bag and become active in water when you open the bag and let it hit air. From all your good information and advice here is what I will try on my next attempt.

  1. Temp acclimate with bag closed for 25-30 min in sump
  2. drip for 20 min with bag in sump
  3. dump n pray

thanks RC :beachbum:
 
What fish do you have in the tank? Are you sure they aren't being attacked by a fish?

I drip acclimate shrimp I get from a LFS because they aren't in the bag more than 15 min, so there's no ammonia buildup. If I get one online, then I just float bag and drop them into water that's the same salinity. So if you are getting them locally, I don't think the drip is what's killing them, imo. And if you're dripping from the DT, then obviously the temperature should be the same. My money is on a fish attacker.
 
This.

I agree. It's often been problematic for me in the past. It seems to make sense but so did bleeding medical patients in the 19th century.

I say temp acclimate but bring the animal home in a small cooler quickly so keep the temperature differential to a minimum. And then just match salinities and get it in the new water quickly. If the LFS keeps the invert tanks near reef salinity, all the better. JMO.
 
Had a red hawkfish that was killing off my shrimp. He was taking out shrimp that were bigger then he was. He's been traded... shrimp problem over.

I too tend to float the bags for 15 minutes or so, net out the critter, and discard the fish store water. Almost all of them treat their water with something. I don't want _any_ of that gunk in my tank.

the only thing I would see is my royal gramma that is kind of a *** but my clown puts him in his place. The other would be a small yellow wrasse that is a very calm tank mate but I did not see either of them pick at the shrimps when I introduced them in.

I will keep a close eye when I introduce the next one.

Once again , Thanks to everyone that replied . I will update the post when I get a new shrimp tomorrow
 
Update ...

I got another skunk cleaner and I set the bag in the sump to temp acclimate for 30 min, at the same time I had a drip line to the bag. The shrimp was active in my cave work for the 20 first minutes i watched. but 40 minutes later it has passed away and getting picked at by hermits and my nasarius snails.

I dont get it , I cant explain why I cant keep a shrimp more than 1hr :S

Dude you did it again.

Don't. Open. The. Bag. Putting that line in the bag screwed you.

Float the bag, match the salinity, pick him up with your hand and put him in.
