I bought 4 1.5" Dats a month ago which were sold as polota which they aren't they are indos, and i have been watching them very closey and have noticed that there is one which is a little smaller which has been seperated from the others. Dispite being smaller it has very strong colours and twice as many bars than the others which are very thin. Could this be a thin bar? I can't get any pictures as they are asways quite blurry.
