He will be fine in the plants, mine likes to hang out in some I have floating near the surface, he actually negotiates plants better than most fish, due to his shape. Try getting a long tube or in my case I have whole coconuts in there (hollowed out of course) which is loves as his home, albeit he is growing out of his now, his tail sticks out but it doesnt seem to bother him.
Mines very active even during the day and hand feeds, so if you get some live/frozen foods, try teaching him to come up for his food.
Great fish, one of my favourites, be aware they are pretty senstive so keep on top of water quality and feed plenty of varied foods.
