Ok, in the past week i lost a royal gramma to ick. Took it back to the store they gave me a replacemnt tank rasied percula. I had my water checked and evverything turned out to be fine. Woke up this morning and the clown fish was dead. Mind you i have had a pj cardinal only in there for about a month before adding the gramma then the clown. Its a 12g nano btw. ont really know what to think of it. Any clues. Water temp and salinty are fine.
 
when i first st up my 12gal nano i had the same problem so one night when the lights where out i shined the flashlight on the tank and it was full of brissle worms. You might try to shine the flashlight on it to see if it's the same thing.
 
The pj cardinal is the only fish in there. I have seen only one bristle worm and removed it. I do have bristle stars though. Ill look tonight. Also, i just notcied that my green button polyps are turning white at the bottome with a few polyps looking to be melting on top. Im not sure what is going on here. I do a weekly 1 gallon water change and add magneison, calium and alkaline buffer aswell as ph buffer. I have seagel, matrix and purigen in the compartments.
 
alright here is my best advice...first thing when the first fish died from ich you should not have added any more fish for some time to ensure that it was dead in your system. also i can't believe bristleworms would kill a clown, although i have heard of some pretty big worms.

why are you adding all of those supplements? on a 12 gal you probably don't really need to be dosing calc, mg, ph, and alk unless you have a large amount of stony corals in there. i would also question if you need to have seagel, matrix, and purigen all running on a tank with 1 fish. i would advise you to stop adding so many "chemicals" to you water and stick with weekly 15% water changes and see if your luck doesn't improve.
 
Ok sounds good to me. i was told by my lfs that i need those things and to add the recommened amount with a weekly water change. I do have about 15 lbs LR and 20 lbs LS And i know for a fact that i do not have any large brisle worms or any worms at all for that matter.
 
i would definitely eliminate all of those additives immediately. if you're not testing for their levels then don't add any to your system. it always surprises me to hear what lfs will tell some people to do. a little carbon should be fine to keep the water crystal clear though.

when you do a water change be sure to aerate your ro/di water overnight and mix the salt for at least 8 hours to ensure it is fully disolved. in emergencies this can be skipped, but as part of a weekly routine i would suggest it.
 
Are you sure it was ich?

I concur with the poster who suggested not adding any fish until several weeks after any illness or symptoms have subsided.

I asked about ich because it may have been something else. Brooklynella is quite common in Royal Grammas (although usually more so during the hotter months). If Brooklynella was in the tank, and you added a clown, Brook can take a clown in as little as a few hours (although they don't always die from it.)

Cardinals in general rarely get sick (with the exception of the questionable pathogen that wild Banggais seem to suffer from, but that's another post). It's quite possible that the Cardinal is either not prone to, immune to or a carrier of whatever got your Gramma and Clown.

What are your parameters? Please post specifics. I don't think the "additives" had anything to do with it - the resins (SeaGel and Purigen) are fine - Matrix isn't really necessary if you have live rock (or was it Matrix Carbon? If so, that's fine). The trace elements and buffers didn't likely have anything to do with it either.

Don't sweat the bristleworm - they are good for your tank. I'm sure you probably have more of them (hiding) - and that's a good thing. They don't harm healthy tissue (fish, coral or inverts), but they will clean up the dead or dying. They are important janitors, so don't try to remove them - if you have an unusually large population of them it could be due to overfeeding - but you did not indicate that was an issue in your initial post.

Hope this helps.

since i have the one pj i usually feed PE mysis 1-2 a day in very small quantities. I do have corals like gsp, xenia, green button polyps and other types of zoanthids. Do they not need magneium and calcium? I also have 7 hermits, a few narrius astrea and turbo snails as well as a peppermint shrimp in the back compartment (he jumped over and is still living back there). Im pretty sure in was ich although im not an expert in fish disease but im pretty sure.
 
It's possible it was ich - I was just considering other things given that two fish that are prone to Brooklynella both died. Ich doesn't work that quickly (ie on the clown) - and clowns don't get ich that often either - but they do get Brook quite easily.

If you are testing your MG and CA levels and dosing is indicated - then that's fine. If you aren't testing, you may wish to test levels and adjust as needed - but that is totally separate and aside from the illness issue - they aren't related.

What are your parameters?

The clown had nothing on him when he did. He was swimmng and eating normally then last night he was dead. Ph 8.3 Salintiy 1.022 which is a little low. Kh 8 calcium 450. temp 79.
 
nitrite 0 nitrate less than 10 and ammonia isnt zero but close to it only because i think i stirred up the gravel bed and messed with the sponges then changed the water
 
What brand of test kit are you using? How long has the tank been running?

Some brands of test kit can give a false positive but if your tank is young it may not be fully cycled.

Stirring up the sandbed in a healthy tank shouldn't cause any problems, unless you have deep sand and a lot of rotting detritus.

the tank is established for over and year. i just no wut the cardinal in about a month ago. i let me lfs test the water and then i double check it. I did have a lot of debris from the filter sponges at whatnot when i cleaned it out.
 
A nano is very unforgiving when it comes to pollutants. Make sure you use no aerosols near the tank and never put one of those *Plug-In* air fresheners in the same room -- especially one that heats and diffuses oil fragrances. These are contaminants that can poison your water and affect the air/gas exchanges. These will also generally not show up on a water sample test unless you take one to a full-service lab for extensive testing.

Agree on *no supplements*. Do frequent W/C's and your essential elements should be spot-on.
 
Linda brings up an excellent point - sometimes Phosphate can be a "marker" for such sorts of contaminants.

However the cardinal lives - so that may or may not be a possibility.

I'm still leaning toward Brooklynella.

LFS may not want to bring a potential carrier into their setup unless they have a place to isolate it (they may have a q system but if they are already treating or holding fish they may not want the exposure.)

I do concur that leaving the tank fishless for 30 days or so should solve the problem though. Even if you can quarantine the cardinal in another tank - in a hospital tank he can be treated prophylactically if need be.
