I like your setup wish i could afford a tank that sort of size! would be a good move filling it up and getting those floating plants as shade as you said if you dont want your axies hiding all day, As for bulbs ive tried a few Hagen sunglo was too bright, Hagen aquaglo abit dimmer apparantly good for plants had a very pleasant pinky bluey light that really showed off colors but my favorite by far is the interpet blue moon moonlight bulb designed for night viewing, it probably not good for live plants but my axie acts as if the lights not even on, no more hiding in his cave for days at a time and has an blue glow that makes the tank look amazing. The downside being if you had nice colorful axies they would all just look different shades of blue rather than the beautiful whites n golds but gomez is grey so he looks better blue haha! Id recommend the aquaglo if you want to accentuate the colors of your axies and the tank while still using a relitively soft light or the moonlight tube if you want to see your axies out and about more often i went for the latter its nice to turn the light on and not have him dart to the nearest corner or cave.
Bet you cant wait!
