Fish that don't eat other Fish

[KenR60]

What eatable fish are available that will survive the outdoors ( Brisbane ) that aren't going to eat my Natives and Goldfish?

Hi Ken,

Dead ones!

Seriously, all fish will eat other fish......sometimes because they are carnivores (golden perch, barramundi, murray cod, sleepy cod, trout) or because they are opportunistic omnivores (jade perch, silver perch) and a small meal just happens to float by. Omnivore doesn't mean vegetarian - it means that (for practical purposes) they'll eat a little of everything given the choice.

But if it helps silvers have small mouths.

One of my clients reported to me the other day that one of his inebriated mates, while having a drink with him in the fish tank shed, caught a baby mouse that happened by. He deposited it into the fish tank to see if it could swim....whereupon it was attacked by the 6 month old the Jade Perch.... and devoured.

I do not know the condition of my client when he "thought" he witnessed this event....but for what it is worth.......

Take a lesson from someone who has had indoor aquariums for many years. The rule of thumb is if it will fit in another fish's mouth then it will get eaten.

Oh Bugger ... I always thought omnivores where just that!!!! Oh Well, anyone tried Goldfish on the BBQ? LOL

Thanks for the advise everyone.

Herbivore = vegies/ plants
Carnivore = meat
Omnivore = both

Placostamous fish are herbivores, but I dont think you want to eat them.
I've heard some folk keeping one in a system to keep the algi down.

I have had algae eaters in my tanks in the past, and they do very well in summer, but can handle the cold winter temps.

I'd say your options are Trout - they tend to leave goldfish alone, or Silver Perch - wrong time of year to be getting them though.
