I would like to start with thanks for all your comments and help with me being a new guy with ponding....as you can see Donald and Hillary are pretty big when you compare them to my Savio main drain....my question is that Hillary is flashing.....against my bottom drain....not a lot compared to what I have read but when I watch maybe 3 or 4 times in a 30 minute period.....I got a good look at her this afternoon and she has four white spots up close to her dorsal fin, she has none on her sides.....that due to her keeping them scraped off on the drain.... I have done alot of research and I think this is Itch....just my opinion.... But I need you guys opinion and about remedys and treatment.....but not sure what to do....Donald is fine no spots and no flashing....at this point in time I have no way to segregate her....and treat her alone...your thoughts would be appreciated....Jimmy
