I am currently out of town till 6/30 and have enlisted my mother to feed my fish while I'm gone, Tonight she sent me a video of my 18" albino clown knife acting erratic shortly before his death during the nightly feeding. All other fish appear to be fine. I did a series of large water changes to reduce the nitrates as low as possible before I left 6/23.

video my mother sent me.

1. What is the size of your tank?

195 gallon display 5x2.5x2 with 55G sump(1400gph) and FX6


2. What are your water parameters? State the brand of test kit used.

Unknown currently, Ive emailed a friend of mine asking if he could come over and do a test with my API kit. Will post results when available.

3. Is your aquarium set up freshwater or brackish water?

Full fresh.


4. How long the aquarium has been set up?

6 months on sump/display, added the FX6 about 3 weeks ago.


5. What fish do you have? How many are in your tank? How big are they? How long have you had them?

1x black Arowana 16" 3 months
1x Short Body Paroon Shark 16" 6 months
1x Albino Clown Knife 18" (dead) 6 months
1x SB RTC 10" 1 month
1x Red Tiger Oscar 12" 7 months
1x Albino Tiger Oscar 10" 4 months
3x Silver Dollars 5" 4 months
3x Royal Pleco 5-9" 2 months
1x Fire Eel 10" 3 months
1x P.tilapia Bleekeri 7" 3 months

1x Tigrinius 6" (sump) 1 week (purchased from forum member)
1x indo datnoid 2" (sump) 2 months


6. Were the fish placed under quarantine period (minus the first batch from the point wherein the tank is ready to accommodate the inhabitants)?

Yes.


7. What temperature is the tank water currently?

Generally kept at 81.5, Set the heaters at 76 before I left to slow down their metabolism while I was gone to help reduce nitrate build up.


8. Are there live plants in the aquarium?

4x mossballs 3 months
large pothos in sump 3 months

9. What filter are you using? State brand, maintenance routine and power capacity.

55g sump with 7" diameter filter sock with ceramic media and 1400 GPH return pump. Last cleaned 3 months ago.
FX6 running just the included media. Its new so i havent cleaned it.


10. Any other equipment used (aside from heater and filter which are two very important components of the tank)?

9 watt coralife UV sterilizer running at 50 GPH.

11. Does your aquarium receive natural sunlight at any given part of the day? What is your lighting schedule (assuming you do not rely on sunlight for our viewing pleasure)?

LED white lights on during day/ low intensity red light at night.


12. When did you perform your last water change and how much water was changed? How often do you change your water? Do you vacuum the substrate?

6/23 70% change. Tiled bottom is generally clean and never has solid particles on surface. due to the position of the return pump from the sump and the intake of the fx6.

13. What foods do you provide your fish? What is the feeding schedule?

General diet is NLS/Hikari pellets, freeze dried mealworms/krill and the bulk of the tank diet is tilapia fillets. fed 2-3 times a day.

Diet instructions while Im gone are feeding 10 cheese cube sized pieces of tilapia once per day to help reduced nitrate build up while I'm gone.




14. What unusual signs have you observed in your fish?

Because I'm not in town I can't accurately answer this.


15. Have you treated your fish ahead of diagnosis? If so, what treatments did you use? State your reasons for planning ahead of proper diagnosis.

no
 
Hello; Well I appreciate all the information you have provided.
Two things come to mind. First and very common is that having someone else feed your fish is very often a bad idea. I have lost tanks of fish due to a novice adding too much food. If your mother normally feeds the fish then this is not likely. If she does not normally tend to the fish this is my primary guess as to what happened.

Next is that the tank has fairly heavy stocking, which even if your mum only slightly overfed might have upset a fine balance.

lastly is that fish just die from time to time. Sometimes we never know why.
 
Hello; For future trips. 6-23 to 6-30 is seven days. That is well within the time that fish can fast and be fine. In fact I found that when away for a few days I came home to a nicer tank after the fast. In fact I now skip feeding a day or two a week fairly often.
Next trip do not get anyone to feed the fish.
 
Thanks for the quick reply, I did instruct her to feed a reduced diet while I was gone. I even included a photo with a dime in picture for scale. She's been feeding about 10 cubic centimeters of food once per day (tilapia). This is probably about a 1/3rd of their normal intake. Shes no expert but I travel to Chicago for work a few times a year and she's fed the fish successfully on my previous trips.

Im hoping it was just a random death and posted this information for more experienced keepers to maybe see something I did not.

I will definitely have her stop feeding the tank. As not to further increase nitrate levels.

I also forgot to mention I had her add 100 ml of seachem prime to the water to help temporarily reduce nitrates. I trust she measured correctly because I have scientific glassware and she is a ER Nurse so she deals with that sort of thing regularly.
 
seachem prime to the water to help temporarily reduce nitrates.
Hello; I may be confused or mis-thinking but I do not think PRIME deals with nitrates. However it should not do much harm at a low dose.

I believe Prime is a reducing agent however and if there is not any ammonia, chlorine, chloramine for it to reduce, it is my understanding that it will take Oxygen out of the water.

Label states you can dose up to 5x normal volume to neutralize nitrates for about 48 hours.

"Detoxifies ammonia, nitrite, and nitrate"
 
Hello; Thanks for the reply. I am mistaken. I guess I should have look at my bottle of PRIME.

No worries, Apparently not even Seachem was aware that prime did this. This extra effect was reported to Seachem by hobbyists after its market release. According to their FAQ Seachem isn't really sure how this mechanism works exactly either.
 
While I'm on vacation I'll set out plastic cups for each day and have it labeled. Or I'll feed every other day and usually just dry food like pellets, flake or something of that nature. I'm always paranoid that something will happen when I'm gone.

For the time of death, I doubt is was due to nitrates. If the manufacturer doesn't know how it renders nitrates harmless, I wouldn't put too much stock into relying on it for this reason.
