Len,
My dream system, and one that I fully intend to implement in a few years, is at this point not a marine system. My next reef, whenever it happens, will be a 30 gallon cube. Anyway, you know that huge planted tank you posted about in the freshwater forum? Imagine that with a group of Severums, some Uarus, some huge schools of tetras, a pair of wild Firemouths, etc, etc.
Depending on what fish I end up with, it may not be a fully planted tank, but a large Amazonian biotope tank nevertheless.
Dimensions are still up in the air, but it will most likely be 96x48x36.
Number two, just a 90 gallon tank with a large show specimen of the fish you see to your left.
Number 3, a very large (like the dimensions mentioned above) tank devoted to groupers. Far and away my favorite marine fish. The thought of doing water changes on a huge salt tank ( been there) doesn't turn me on though.
The mind bending cost of stocking a large reef system, accompanied by anxiety any time I leave town, the danger of power outages, power use, etc has put me off of large reefs for good. I'm not willing to spend the money to recover from a disaster. I need systems with a large resilience factor at this point.
I'll always be a marine aquarist, but I'm turning my primary focus back to my first love, the family Cichlidae.
