I think some sort of gill parasite has come in with one of the bunches of loaches I bought.
The fish are flashing (turning sideways to scrape the side of their face against rock/wood then turning back to swim normally) with some frequency and seem overall uncomfortable.
Sometimes when they flash on a completely clean surface, like a granite rock, I see a 1mmx1mm roundish brown thing come out of the gill when the fish flashes, as if it has scratched the parasite out of its gill. It is too small to scoop out and I cant get a photo... its just a roundish brown thing. Im sorry thats a pathetic description.
I've made drawings also here- the burmese cross breed loaches are 'yawning a lot' (image 2) where they curl the barbels all back to reveal the inner 'mouth'. Image 1 is a normal mouth. Also, one of the burmese cross loaches, only just today, has been holding his barbels in a rather unhappy pose, as in image 3. He appears rather timmid to the other loaches today.
Also the burmese are being very beligerent, appearing quite frustrated, and are taking it out on the rostrata by tryint to bite their caudal fins.
All my fish show symptoms except the plecos. The bolivian rams are flashing as well, and on occasion are coughing and fluttering their fins and fidgetting their bodies in discomfort.
I need a recommendetion for medication please
(bolivian ram, brislenose pleco, burmese X loach, rostrata loach, aeneus cory)
I would greatly appreciate this. Thank you.
Water parameters have been checked by the way. pH is 7.0 ammonia nitrite zero nitrates are under 10ish ppm...
