Hi, as ive said in my previous posts, I just started a new pond filled with predator fish juvies(mostly around 10cm each)
-arowana
-2 oscars
-3 rocket gar (freshwater barracuda)
- 6 tinfoil barbs
-3 endlicheri(snakehead)
-2 plecos

Im currently feeding them crickets and grasshoppers(freshly caught from my backyard, there are lots), frozen bloodworms, and feeder guppies which i buy from the local aquarium shop and keep them in a tank to quarantine them. I want to add a little more food diversity to it so that they can get the most out of the nutritional values. I was thinking of maybe getting some frozen tilapia, live feeder shrimps or dried maggots. Would they be okay? Feel free to leave suggestions or questions!
Thanks!
