I have a cinnamon/tomato pair that has been together for about 8 months. The smaller one is hosting a large cluster of zooanthids in my tank. The larger one is around the same area but will not get in the zooanthids. Is this normal for them to host a colony of zooanthids? Also, if the larger one is still in the same area(no farther than 5 inches from the smaller at all times) are they more than likely still paired? I am going to try to add a small ceramic tile to see if they can use it to lay eggs. Thanks.
