It seems that T. proximus are different from T. sauritus then. Kleo preffers food from water; she takes guppies (her favourite food) from tongs and once or twice took smelts, but that's it. If I hold a scented pinkie or smelt right in front of her nose she KNOWS it's food, but will ignore it until I drop it in the water. I mean she expects that proper food will be in the water and needs to be hunted down, even if it's a pinkie.
