It's a coralife fixture with one blue light and one daylight. They used to be skittish a while back with both daylight bulbs, it was too bright. But the blue lights really show off their colors and it's dull enough they're constantly active.
I see so many umbees around here but no love for the more manageable smaller growing species.
are they harder to come by or just not popular?
heres one of my Caquetaia Spectabilis about 5-6"
I've never owned an umbee but from videos they seem to have a different personality to Spectabilis.
I currently have two and they are very much like datnioids. Ambush predators first, show little overall aggression and can be shy to take pellet food that doesnt resemble the shape of fish.
This guy doesnt pound the pellets down like an oscar, he stalks a single large log shaped pellet and then swallows it whole, swims away and hides in a cave.
