hi, i seldom use meds on my fish but would like opinions on which meds are safe to use on plecos, corys and other cats, is there a fairly comprehensive list of what is safe to use, or those to use at halfdose only or not at all. i have a gill and body fluke outbreak in one of my tanks that contains some corys and an otocinclus, would like to use sterazin but is that safe at full dose?:dk:
