OKAAAAY! Another update. Now I'm REALLY confused. Apparently, the questionable female/male ram that I purchased from Petsmart that I suspected was a female, but then thought it must be a male because it paired with the one I was sure was a female is now almost certainly a female.... The eggs that were laid a couple weeks ago never developed and I thought there must have been something wrong with my tank parameters (too high nitrates--40?). So I vacuumed the aquarium and did an almost 50% water change.
Over the last few days, I've noticed that female (or male) ram behave very friskily with the male I purchased recently and both of them are chasing away the ram I know is female. Also, I noticed that the breeding tube on female that recently laid eggs is much smaller than it was when she was ready to lay eggs and now the other female, that I though must be a male, now has a HUGE breeding tube and is acting like she's ready to lay eggs. Is it possible that a female could be 'confused' about their sexual orientation and pair with another female?
This morning, I noticed that the ram in question is rubbing her/his/her belly against the bottom of the tank, cleaning one of the rocks, darting around, and lip locking/dancing with the male. This should be very interesting.
