Aaaah, larger fish are typically faster and capable of displacing more water and because of other biological adaptations. Notice the fastest fish are fish like sailfish, marlin and tarpon etc

"That was just the fish itself being lazy and not wanting to have to chase over a smaller meal. The smaller fish are faster and harder to catch due to being smaller. Bigger fish are slower and have a larger surface to bite onto, which means a higher chance of catching one, and in turn a larger meal."

That basically the explanation I got from the rhom owners. Not worth the chase. I've heard that argument before too about other large fish. Talking about feeding oscars goldfish and it being natural. In the wild a big fish isn't going to burn a ton of energy chasing a little baby fish that won't replenish the energy spent chasing it.

I've seen loads of piranhas kept with small fish and the piranha just ignore them.
I never tried this myself when I used to keep natteri years ago.i imagine juveniles would be more likely to chase down a neon than an adult would.
I have also kept chocolate cichlids and satanoperca species with small tetras without issue.

Notice we don't keep sailfish in aquariums.

A lot to consider. I tried a mbu with a 100 gold tetras. I slowly lost all of them. flagtails would work.
I had severums before... they dont eat whatever fits in there mouths?

I keep Geophagus redheads and dicrozoster with my school of 3 dozen tiger barbs. They don't even bother them at all.

Where can I buy those GEOs? very beautiful. I live in Dallas TX now.
Thanks! We bought them as adults at our local fish store. They are all males, so they get along great with each other. A little gill flaring by the two biggest males, but nothing else. The store owner wanted to breed them, that's why he sold them to us.
