hello, i have 3 chromies , 1 blenny and a mandarin in the quarantine tank. they've been in the tank for 25 days. the temp in the QT is 28c (82.4f) .. i've thought the chromes had some ich at first , but then when i checked them, their fins are fine, since im running a bubble diffuser in it and two filters "no skimmer" .. im planning to leave one behind in the Qt to keep it cycled and i might drop some cheito in there.. i haven't used any type of chemical or medication .. but what do you guys think? should i go ahead and use copramine ? i also have prazipro .. so far the fish are eating healthy. the fins are clean.. no sign of ich outbreak. should i go ahead and treat them for a week? im afraid that the medication would cause more stress
