Hi, i'm new to all of this and have a few questions if anyone can help me
First of all i have two clown fish and they seem to have taken a liking to a certain area on the rock in the tank and they keep rubbing themselves against it and biting at it. They also get really aggressive whenever another fish comes near it. Would i be right in thinking they are preparing to breed?
Secondly i also have two damsels and one has been going to the corner of the tank and fanning the sand with it's tail so that a big hole appears. Is this normal?
I have checked all of the levels for the water and they are coming up fine.
Also, are there any guidlines on how much live rock you should have in the tank and when it's safe to add an anemone?
