Hi there,i have a 180ltr rio with 10 barbs 8 clown loach,at least half the fish are flicking,been goin on now for a month but i dont want to add meds as loaches are sensitive and i dont want to hurt the clowns as they are so nice,i have brought waterlife sterazin,is this safe for them and should i use half dose,i really have no idea,any help would be much apreciated.
