i had a pair, they require feeders.
DO NOT KEEP THEM WITH CICHLIDS.
i lost my needle nosers to broken backs.
they were in my 120 with my sa-ca's for like 2 months and i hadn't yet had much expierence,
one night during feeding my oscar broke one of the gars back' by bitting his bottom jaw
while the gar had a feeder in his mouth, he seemed alright but in the morning, snapped back.
the same happened the next night but this time i never caught any of my fish lol.
they love the top and will eat any fish that they can fit into their mouths.
they also enjoy the dark and will swim more in dim light or no light.
