I found in my smaller community tank my small loaches scratching a bit and found no ick so I'm suspecting gill flukes. I'm thinking of dosing with prazipro but was wondering if I should lessen the dosage since they are loaches in which they don't have scales and also the tank has a few plecos. I've read that plecos don't do so well with certain meds and I'm kinda weary of dosing the tank. I'm thinking they got it from me not quarantining new fish (bad habit). Any help would be greatly appreciated.
