Fish Symptoms (include full description including lesion, color, location, fish behavior): the fish are generally active and look from the outside healthy with no visable particular bloating or thinness or lack of colour but some do flick every now and then on leaves or sometimes the gravel.
the cories show the most symptoms with some darting around for a second or so looking like they're not comfortable every now and then (i assure there is no problem with the gravel which is roman jet black smooth and small) and i've seen the halequins do it but more rarely.
a few of the cories also hover mid air some of the time with the head pointing downwards and an angle which i don't understand what causes this.
all seem to have good appetites and no fatalities for months.
i guessed at a bacterial problem or some kind of parasite which is why i used the medicines said below but a few treatments of interpet and one of sterazin the same symptoms persist which is really getting me down not knowing how to get rid of this.
suggestions for possible other treatments or more info needed please ask, i'm from the UK too, btw.
