that's so cool!!!
i always look at your fish and dream...... gonna get my head around a 'standard' marine tank before i try anything like you have though
Why bother with a 'standard' marine tank?
My first marine fish was the frog in my sig. Fish are far easier to keep than corals as there is far less problem with salinity (all reef fish can take 1.021 to 1.026 without much bother) and they can suffer far greater swings in other parameters and elevated nitrate levels.
I only have a reef to placate the Mrs, otherwise I would have more predatory fish. The only downside to my newest pair of fish is getting them to eat dead. The newest frog is currently scared of teh feeding stick and I don't have anything quite the right size really for the scorp yet.
