Predatory stocking options 90gallon

[Danielslo]

Hi all, 

I am currently working on a 90 gallon project with a 30 gallon sump.

I was wondering if I could put up a predator tank with a feeder fish of some sort. (Possibly livebearers) 

I thought about Red wolf fish (single or pair) with endlers for instance. 
 

Any thoughts, suggestions or alternatives? 
 

Thanks in advance.

Sounds good to me. There are always types of freshwater eels, too. But since it’s 90 gallons, you can’t fit many well known predatory fish in there. You could maybe do some young vampire tetras, yet they will 100% outgrow the tank. All I would do is go to a local predatory/exotic freshwater fish store near you and check out their recommendations.

Smaller species of bichirs, like palmas would work perfectly, but keep a tight lid.
