Thanks...The Ctenopoma gets on well in my community, but there is no small fish, except for an Oto. I've read that they will eat smaller fish, but I've seen no aggression from my little guy. He's still small yet, though...
Your guess is as good as mine! The big ones were labelled Splendida Rainbows. The others were labelled Australian Rainbows. I did research, but there's so many, and I didn't have the patience.....
