PS - I'm sorry - in your post I didnt get the sentence where you said you fish died. I'm really sorry - I hope the information I tried to provide helped some - for the future.Hey guys! Update time, sorry, it's been a really frantic 12 hours. First off, this has been one of my favorite discussions to follow on here, I just wish it wasn't because my eel was dying. Thank you everyone for all the help, but things are getting really weird again.
First and foremost, I'm using the standard API saltwater test kit with calcium and phosphate testing added. All tests are within 1 year of shelf life and I test the water about twice a week now running a log. Ammonia is usually lower than that .35, but my wife was feeding dry pellets and probably overfed while I was on a trip for 4-5 days. I figured the higher ammonia was her overfeeding my fish. She fed the eel on the schedule I gave her with tiny chunks of frozen shrimp. For those saying malnutrition, the shrimp isn't frozen brine, it's large grocery shrimps I keep a bag of, cut pieces off of, thaw out, then feed to him. One question I have is if she didn't thaw a shrimp chunk out completely and he ate one with a frozen core, could that lead to his death?
Regarding the fate of the eel, by the time I got home, he was dead. I felt around his throat to see if something was lodged in there, but couldn't find anything.
I'm questioning everything now, as I did a 21 gallon water change (20 gallons, then an extra gallon for what was thrown out of the protein skimmer when I cleaned it) and the Nitrate level went from turning bright red in less than a minute to almost 0 the day after I changed some water. No other fish in the tank are affected by whatever affected the eel and as a reminder to something I said earlier, he only started showing signs of not eating a day or two ago. His stomach was not impacted and I had a friend take a look at him to let me know what he thought the condition of the eel was and was told he was the proper weight/thickness for his age/length, so it wasn't underfeeding.
So now, I'm questioning my test kit, the use of chemiclean, and everything else in my tank...
I bought some activated charcoal (I believe it was seaclear brand) that was recommended by a LFS and a large mesh bag. Since I've been using the Magniflow 360 canister filter cartridge and the marine land brand charcoal pouches, I've never liked that they don't cover the entire shelf they sit on, so hopefully this gets better filtration? Other than that, I'm at a loss for what I should do other than just watch the tank and see what it does.
