I have at least 5 adult males and 2 females. I never noticed any of the females change shape but I now have lots of BN fry zipping about and have no idea who did the deed, or where :-?
Very heavily planted tank with large bits of driftwood in it.
I got our club members to count them at the meeting to prove I had over 10 (they are over a month old) so I will register them with the breeding scheme 8)
