Clown loaches and the struggle with ich

[leeD]

Well I really enjoy clown loaches.. We keep getting them at work..new shipments.. different suppliers.. and always they aquire ich in our system and on our seperate tanks.. We got new batch in and they were doingt really great..like amazing.. so i took 3 and put them in with my arowana..they were doing great..but now they have ich and 3 other ones in an angel tank i have.. Does everyon else have this problem with these fish? they seem super super delicate.. more so than my discus... Any tips? and how should i treat my arowana tank..? emphasese on not hurting my arowana at all..
