  1. Question Golden Pencil Fish dropping like flies?


    0 Not allowed!
    So I managed to get the LFS to order me in some golden pencil fish after searching around for them for a couple months since starting my tank back up. Well, the research I did on the fish seemed to show that they weren't any harder to take care of than cardinal tetras, of which I have a school of a dozen. I picked up 8 to start with since they're pretty small and require a school to feel safe. Two died within 12hrs and then the rest seemed alright. So I took the two dead back to the store, got them swapped out, but also picked up 2 more, bringing the total to 10. Now three days later I'm sitting at 6 fish, almost one fish has died per day. Before I added the fish I had performed a water change and made sure my water parameters were in the clear, which everything checked out. All my tests show my water is still pristine, so why are they all dieing on me? I keep an acidic soft water aquarium which should be replicating the native environment for these little guys. The 6 I have left however have all colored up really well and are eating well, so I hope I don't lose anymore. Is there something wrong with my tank, or is just because the fish are from a chain store and who knows where they came from?

    Water parameters:
    pH- 6.0
    nitrite- 0
    nitrate- 0
    ammonia- 0
    kh- 71.6

    Nitrate should be between 5 and 15 ppm. Zero nitrate is indicative of uncycled tank. Your pH being 6.0 is very acidic and at the lower thresh hold of acidity tolerance for those fish....but in the thresh hold none the less.

    Overview sounds like you are knowledgable about fish keeping, many times the shock of transporting fish is just too much for them. How did you acclimate them to the new tank? HOw long were they in the bag? How cold did they get in transport? (wintertime is rough on fish). Sometimes, unfortunately, fish will have a death sentence before they even leave the LFS tanks and its just rotten luck.

    Give it a week or two and if the remaining 6 fish are thriving, then try again to boost the school to the desired population.

    The nitrate in my tank always goes down to 0 right after a water change, it's normally around 5-10. It's takes a few days for it to bump back up.

    I don't have any special acclimation supplies, I sit the bag in the tank until it becomes tank temp, then I empty about a quarter of the water out and refill with tank water, wait a little bit and so on and so forth until most of the water in the bag is tank water.

    They were in the closed bag for about a half hour/forty five minutes because of the drive back from the store+acclimating to tank temperature.

    Not sure if you're referring to the shipping transport or the transport from store to home, I obviously wouldn't know the first one, but the weather where I am was warmish the night/day they shipped into the store, not tropical warm though, probably was around 50-60F. On the drive home they stayed at room temp, which is the same as they were in store. The store I shop at doesn't do anything special for their fish, they all have the same water, same temp, same chemistry. They also I believe only use tap water, which where I am is ATROCIOUS for fish. I don't really shop with them much except for plants, they just happened to be able to order these guys in and petsmart wouldn't.

    Yes, yes I do. The tap water where I live is god awful city water, it has chlorine, the kh is off the charts (when I used the API liquid test, I used 16 drops in the test tube of water and it NEVER went yellow). So I use a mix of dechlorinated tap water with RO water that I get from a fellow aquarium fan. The tap water is then additionally treated with Seachem Acid buffer, which supposedly also softens the water by particulating the minerals in the tap water and makes them precipitate out, which then gets sucked up by my filter. The tap and RO water are set to the proper pH before being added to my tank. A water change seems to take FOREVER, it takes at least 4 hours while I wait for all the chemicals to settle to be sure that my tank won't have any water swings. Of course the reason for the RO+tap mix is to keep some minerals in the water to keep it buffered enough so the pH doesn't suffer any bad swings and stress. All in all is sort of a pain to regulate a soft water tank where I live. I also keep peat in my filter, that was more to make a blackwater effect, but it hasn't worked yet :/.

    I just performed another Nitrate test and now they're between 5-10ppm. It's always so hard to tell the exact color lol.

    Could the replacement water you add after a water change be at a different pH the tank water ?

    It does sound like you are taking all the right steps to prevent this. I was just wondering if you had tested the pH just to double check. That would be my only guess as you did not mention if you have tested the pH or not in your above post.
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    In my long winded reply I mentioned that I do make sure that the pH of the water entering the tank matches :)

    + 1 to above - You "keep" an acidic soft water aquarium - Does this mean you are doing something to alter the pH in your tank? For how long did you acclimate your fish before putting them into the tank?
