I'm getting my first rays this week. A pair of retics. I've been doing my research on here and think I'll be ok. I was wondering if they could be kept with Geohpagus sp. "Redhead Tapajos". I think they would be a nice touch in my show tank. The geos as you may or may not know are very peaceful, they don't even bother my lemon tetra's. I know thet the rays may go after the tetra's so if I see that I have another tank for the tetra's. Any insight is appreciated.
