Hi Deb,
Thanks for the feedback about your
Chaetostoma. I'm glad you've had such good fortune keeping rubberlips before. Are yours the same species as mine? I don't know if all species are equally rugged and adaptable (my impression is that
/
may be a little better, but I don't have first hand experience to know; as for
dorsale, I like them much better than
formosae, but the
dorsale seem to be a sensitive species, at least for me).
I mentioned PetSmart and Petco because I bought this same species from those stores in the past and I had awful luck with Ich and fungus while the fish were still in quarantine. I lost so many fish (13, if I recall correctly), all within 2 weeks of purchase. I really like
Chaetostoma but I've avoided buying any more since that experience because of (a) the generally poor health they have on arrival (often with ich and sunken stomachs), (b) the challenges they have adapting to captive food options, and (c) their need for cooler temperatures, which I have trouble providing at home. But I set up a cool water tank (<75F) at work and a friend gave these to me from an independent LFS which generally has healthy fish. These particular specimens have decent stomachs and no signs of Ich, so I thought they are worth a try.
As a biologist, in all my years of research I have not encountered a symbiotic animal in the mouth of a tropical fish. These white things move like leeches and flukes; I'm inclined to suspect a fluke. I handled the fish a lot yesterday trying to get the mystery organism out, with no success. So I won't attempt to remove the mystery organism again unless I anesthetize the fish first, so it is relaxed and not struggling. On Facebook, someone reported to me that they've collected plecos (not specifically
Chaetostoma) with leech-like parasites in their mouth. This appears to be something similar.
If I am able to recover one, you can bet I'll get it under a microscope and take more photos (or video if my medication doesn't kill them all).
Cheers, Eric
