I would have to say that I am not totally satisfied no.
I really do not see how I could be for one simple reason.
As my fish grow, I am finding the need to rearrange to repopulate or depopulate as per the fishes community sense.
For example I have a 5 ft 150g that served a good purpose for my frontosa till most recently. I took note that 3 of my ladies have fry and I would bet it is a constant source of food for the tank. With that in mind, I am making plans to split my colony over 3 tanks, the 150g, a 230g and 300g. For I did indeed get that many frontosa for the purpose of breeding them and being able to sell the fry.
There is also the point of predatory fish that are now the size where they can easily fit a 7inch + fish in their mouth and they must be moved to a tank where they are free to swim but not enjoy and endless supply of expensive feeders.
Then there is my sw, which is roughly 8 mths up. Definitely a work in progress and as the tank matures, it is my hope to be able to look at developing a coral angle to the tank.
The final reason why I do not think I could ever be totally satisfied revolves around my fishes well being. I really think that fish are very smart and they do very much enjoy a change in surroundings, if their looking about after a remake says anything. There is also the need to move the sand substrate to make sure that gasses are not being trapped, to do so necessitates the removal of all decor so why not a remake at the same time.
