Thank you for all comments.
With the consideration of your comments, I had a little search on internet and I belive this is most likely a Guttulatus or a Hartwegi.
This is quite pitty since I travelled all the way to England in order to get Zonatus from a Jeff Rapps fish importer .
Anyways again thank you all.
Just to let you know, (not sure how big yours is) but I purchased 4 blu/red head Fens, 4 piebold Fens, 4 Hartwigi, 3 Zo's all around 1.5". I had 15 fish that I had no idea which was which. Its not until they started hitting 3-4" before I could tell them apart. So if yours is still under 3", you have to give it a little more time.
Shawn thank you for this important information.
I bought 3 of them and biggest is just under 3''. Then I will post new pictures in 3-4 weeks time and ask for your comments.
It has been 5 days, pictures belong to the first day in my tank but not so much difference since then.
By the way, there are some variety differences mentioned in the internet for Zonatus; pasific area and atlantic area. Does anybody have any idea?
