Fish die within 24 hours!!!

[Tenshoa]

They could be scared of your forum handle.

Out of curiosity, what kind of time frame did you add all these fish? You said a few days apart. How many is a few days and are you adding multiple fish at once?

Also, are the fish disappearing? Or are you finding them belly up? If so, what do they look like when you find them?

Are you using RODI water?

My brittle star is a foot and a half wide and has never touched a fish. +1 on swirly with the pistol though. He used to get a few of our fish before we removed him. Anthias especially

it is only a matter of time...I found my green serpent eating a new fish I put in...they don't stalk but they are opportunistic and given the opportunity can and will eat fish. the brittles are also in this category...regular serpents are ok.

I just added a red and white striped serpent a couple days ago. My first serpent. Took me a lil while to get past the "serpent" part of it all. lol. Anyway, no issues with these type?

 

[Swirlygig]

most serpents are ok...just not the green with the thorn like spines....the smooth ones should be safe. I have one in my tank.

Green serpent yes, but I don't think I've heard of other colored varieties taking out healthy fish.

As for the OP, I have 2 serpents in my tank and they have never gone after fish or any other inverts unless they were already dead. I also highly doubt the randall's pistol would be the culprit as they are pretty small and somewhat shy. I have a tiger pistol and a randall's pistol in my tank and not a single fish has been harmed, in fact my tiger pistol bolts into his hole whenever any fish comes by. I have heard of tiger's going rogue but never a tiny randalls.

What kind of pistol did you have?

We hd a huge Tiger

Now you have me worried, we have our few remaining "first fish" in there. Might just move him tanks and get rid of the risk all together. When i say he's big, I mean it"¦. you just see 10" legs sticking out of the rock work at night. I always thought he was just a scavenger / filter feeder

some of new fish they live in aquarium only 3 days-2month,even they eat fine,

50% fish alive n used to home aquarium after few month,it's normal,

did they eat good in qt tank?
qt tank got copper or other medication? if not,75% new fish will lost,

ok

no, it isn't normal

75% death if not medicating the qt? huh?

8/12 no QT: Royal Gramma
9/7 no QT: Wyoming White Ocellaris
B & W Ocellaris
Royal Gramma
9/20 no QT: Royal Gramma
9/25 no QT: Sunburst Anthias
9/27 no QT: Sunburst Anthias
11/10 QT: Wyoming White Ocellaris
11/17 QT: ORA Black Snowflake Ocellaris
11/19 QT: Blue Spot Jawfish

All died within 24 hours of being in my display. The blue spot lived in my QT for about a month and the Black Snowflake was in QT for about a week.

I've found all of the dead fish with the exception of one Royal Gramma stuck to me MP40. My seprents got the one Gramma before I had a chance to get it out. The all look the same dead as they did alive. Sometimes I've noticed a white milky coating on their heads while still alive and breathing heavily. They have always died within the hour when I see this.

Yes I have an RODI filter. TDS: 0 exiting the resin and in the storage container.

I'm sorry I refuse to accept that and if that is accurate than we are all horrible people for willing killing that many fish.

We had a huge Tiger

Mine are about an 1" long, tiny and won't get much bigger if at all. Still not ruling them out but it's a stretch.

I haven't had any issues with my serpents. Besides, if the serpent killed the fish I doubt I would find the body. My Randalls are also very shy and never come more than an 1" away from the burrow. The only time I hear them snap is when the serpents stick their arms in the burrow.

I can offer the following observations with regard to the clowns:

• Your parameters are not the problem.
• Your drip acclimation is fine.
• Healthy clowns do not die in 24 hours.

This goes double for a tank raised clown.

I agree the most likely cause is a predator. My wild guess would've been an emerald crab cause they are the devil. Both pistol shrimp and serpent stars seem like a reasonable candidates. After reading your responses, I'm left with the following questions:

1. What time did you add the new fish?
2. Did you feed the tank before and after you added the new fish?
3. Did the new fish find a place in your rock?
4. Do you have a crazy amount of flow in your tank?
5. How often do you feed your fish?

This is interesting. Any other fish show this problem? Maybe one of the existing wild fish had the problem for a minute when first added?

Do you know what Brooklynella looks like? "Milky white coating" + tank raised clown death in 24 hours are both strong indicators.

I don't have any emerald crabs not even hermits.

1.) Same as when they were alive. I inspect the fish before I flush it and never seen any signs of aggression.
2.) Generally, late afternoon.
3.) One or the other but not both.
4.) Most of the time, yes. Clowns, no.
5.) Yes, (2) MP40s on 100%, 90g (36 x 24 x 24)
6.) Daily

Every time I've noticed this the fish is dead within the hour.

Only from google images. Again though, I'm extremely hesitant to gear towards disease because none of the other fish in the tank are affected and two of the fish lived in my QT for a while only to die within 24 hours of being introduced to the display. Also, the rate of infected fish would have to be astronomical to lose this many from the same disease.

I don't see anything wrong with this but I add new fish differently. First, I add all new fish maybe 1 hour before lights out or at least with the white lights off. I always feed the existing fish till saturation before adding a new fish and just after so the new guy can join in. Lastly, I reduce flow considerably (try to match QT for example) for at least 24 hours after adding a new fish. The purpose is to minimize stress to the fish from; aggressive tank mates, additional exercise, new and intense lighting.

It sounds like you've mostly ruled out predators. Based on your answer to 4, my next wild guess is: the clowns are trying to sleep on the MP40s and getting stuck which kills them.

but that would still leave the royal gramma, anthias, and blue spot deaths without explanation.

No. It is not normal to lose 50% of your fish in an aquarium after only a few months.

I have never used copper or other medications on fish during QT and have not lost a fish because of this.

Don't know where your pulling these numbers from.

While in general I agree with you, let me share my experience with Brook. I have a multi-tank system that houses 8 adult pairs of clowns. Each pair of clowns has it's own tank and the tanks are all filtered down to 100 micron with a sock. I added a pair of fish on Monday night. On Tuesday morning, one of the new fish seemed listless. On Tuesday night, most of the fish were covered in thin white film. I woke up Wednesday to several large fish laying on the bottom of the tank gasping for air. I treated aggressively for brook and won... but juveniles would not have made it.
The new fish I added were not quarantined because they came from a beautiful healthy reef with tons of other fish showing no signs of distress. I learned that just because some adult fish in a tank aren't showing signs of disease doesn't mean they aren't infected.
