Jasenka,
I cant believe I'm just now seeing this thread. Your tank is gorgeous! I'm very impressed with what you have in the tank, especially since you say there are no good stores in your country...
I'm very impressed with the aqauscaping and the obvious good health of your tank, despite you saying you dont have anything fancy like a protein skimmer etc..
Do you have a sump for your tank, or are you not using one? I would also like to see more pictures of your tank. Closer pictures of each side would be nice so we could see more detail of the reef.
Your photography skills are very good, thank you for sharing.
BTW, thats an unusual growth pattern for a Seritopora coral...nice color too.
Nick
