Looking good so far! I would suggest after confirming tank cycle, that you start with either a chromis or a yellow tail blue damsel and see how they do before you invest in the other things on your list. I would advise against a seahorse especially for the other things you want. Clownfish are good but stick to the smaller variety, perc's etc. maybe a nice anemone as well, but make sure you put sponge over filter intakes to prevent it from being sucked in, peppermint shrimps are good for aptasia most of the time and a cleaner shrimp is nice as well. stick to softies and mushrooms etc, I will see if I have any pics of my 27g tank at work, easiest tank I have got to take care of and I abuse it regularly{maybe thats the secret}, With small tanks I believe the secret is the K.I.S.S. theory, Keep It Simple Silly. I have customers who come in and stare at my tank for ages, so it works well. You are doing great so far though.
