i have a frogspawn in my tank in my classroom that is doing very well, and that is a 29 gallon tank with a 96 watt pc light. it sits about mid level in the tank. it actually has more color than a frag of the same one that lives in my big tank with lots of light. the eel will eventually be a problem because they will knock things over in the rocks to arrange them the way they want and they just make a lot of waste. many people on here (garyp.. :innocent ) really hate damsels, but i think the right kind are ok. i have two schools in my big tank, green chromis and three stripe humbug. the humbug are starting to annoy me a little, because one of them now defends his pile of rocks by moving things he can and biting me whenever i am close. the puffer will eat a lot of types of coral, and again is a high waste producer - i know, i really would love to have one in my reef tank also, most personality of any fish i have ever had. the angel, depending on the type will also eat corals and sponges. if you get a pygmi, like a coral beauty or flame, they are supposed to be more reef safe, but i have heard horror stories.

ok enough rambling for now.
