It's a bit hard to keep up with all the threads about sick fish sometimes just because there are so many new ones every day. :( I know what you mean about it being hard sometimes to get sustained help. Most of the time when a thread reaches its second page, people stop looking at it and assume you got the help you needed without looking to actually see if the problem was resolved - that's why I always try to keep my posts involving unsolved problems 1 page long.
Sorry, I don't know anything about sexing juvies or I'd have posted in your thread. :c I actually did look at it (before this thread) and they're all adorable!
