cannot place a black habitat on my island

[aikoota]

Hi, I'm new here. At dragon story I have reached level 31, near 32. I have been hatching a night dragon for which I need a black habitat. Now that I have earned enough coins to buy it, with enough place for it, I am finding myself in the situation that I cannot place such a habitat on my island between blue or green habitats. Is there any restriction for this? I couldn't find any info about it.
I have been clearing space on two other islands, but it is impossible for me to lead a new habitat onto it.
Does somebody here know how to help me?

You can place habitats anywhere unless you don't have enough space. To move a habitat to another island hold your finger on it and slide it to where you want it to go and then let it go and it will have moved. Another way of placing a habitat on another island is to have the space you want it to go in the middle of your screen and when you go to buy it it will be more or less in the right place.

Hope this helps.
