Good Tom:)
You are right about zebra 04, I also belive those two are males.The one with his strips grown together(the one at the top) had a vistit a few days ago.He was blocking the entrance the whole week....but nothing happend..

However he was not involved in the video taped fight.
I had eggs last year,so i know i have at least one female,but the last few weeks i started to belive that i might have more...thats is why i need your input..
I hope that you are right regarding the females
One zebra was not in the pics,he/she lives under the heater,where he/she has been digging i ditch for himself/herself,even if 2 caves are unoccupied.The zebra is only 4-5cm or 1,57 inches.
3 zebra are in another tank,i will take pictures of them later today...
