I have a pair of these guys and they do well enough, but really these fish are happiest, and will make YOU happiest, in a group of at least 5-6. Males will spend as much time displaying for one another as they will for females, and are generally at their very best in the morning. They have a white stripe down their noses that flashes blue to white very quickly, it's pretty impressive.
Mine like some planting, but definately need swimming room as they're quite active, though i recently put some fake floating plants in the tank (as my real floating plants died and did horrible things to my water while i was away
) and they are having a blast darting through them. I think the TFF profile says that a 30 is the minimum, but if you go that route, try to get a 30 long rather than high. Mine are in a 29 long and although as a pair they seem okay, i think a proper shoal would look crowded. I can't wait to get my 55 set up so I can keep a nice school
They're quick feeders, but very rarely seem to pick at anything on the ground. When they do, it seems to be more that they just happened to notice it than were actually hunting for it.
I've been told they're slow growers, but not sure on the truth in that.
Make sure you have a lid, they can jump! I had my water level down maybe three inches and while displaying for the female, my male jumped and hit the glass lid so hard he moved it.
