Throw out the old watts/gallon rule when you're talking about T-5s. I have a 4xTek T-5 hood over a 46 gallon, which comes to just over 3 watts per gallon, and I've been able to keep certain acros on the bottom of my tank. Montis don't need all that much light, so I think you'd be fine with those. Rics are great for color, and they seem to play very well with other corals. Echinophyllias are great corals if you can find them! I have a red and green one that's very cool. Be careful where you put them, though. They have pretty good sized sweeper tentacles. Of course, that seems to go for most of your LPS.
