When you bought your fish is there any dead or dying fish in the dealers tank???If have then that is the one may cause the trouble of dying fish.The wild scalare is difficult to take care.I took care some juveniles and it is very prone to fin rot.All my other fishes do not have except for the wild type.I now still quarantining them.The one marbled angel only got white spots so i treated the whole tank because there is a huge outbreak with general aid med that is used to kill common parasites and diseases.And my marbled angel now doing fine see my avatar.(It's actually begging for food there)
