My Mom has always enjoyed our SW tanks from afar but has finally taken the leap! We set up a 5g hex nano for her on the weekend. So far only a couple hermits for activity and a lot of rock...I like a lot of rock...(and I set it up so...

) on the rock there is a large mushroom and a couple of orange ball anemones. They are a very cool hitchiker anemone that is really pretty and multiplies fairly well. Here is a pic. To add fish soon as the substrate is from our 50g and so is the rock and water so all are very very well aged and we don't expect a cycle.
(And she says that all she wants is a 5g and will not want bigger BAH! We know better!)
