Almost nothing is allowed into Australia apart from a silly little list of bog standard stuff.
The other 1 i have is a male also judging by the lack of width around the stomach region.

so is it safe to say in australia they could be pretty hard to find? think iv got 3 males

Thank you very much that looks about right. Are they fairly common?

Best way with these is viewing them from above most females are much rounder in the stomach region. If you can get pictures from above that would be good.

Sorry about it being upside down I'm on my phone internet.

is this one good enough?

I bought three fish all similar to this when smaller as L104's they are now over double in size (about 9-10cm) and look nothing like my L104's. any idea?

cheers jack
