Large non aggressive fishes

[Moontanman]

Ok dudes and dudettes I need your collective knowledge!

I want to put a large fish around the size of Pink Tail Chalceus in a large, 225 gallon, tank with small fish like cardinals. I know the Pink Tail Chalceus far to predatory to add to my tank but I think that a large active fish swimming among the small ones would be a very interesting sight.

Anyone have any suggestions? I have searched google for several days now but no luck. in my 50 years of fish keeping I can't recall any such fish, possibly I am going senile but I vaguely remember do this many years ago but the species of fish eludes me....

Any suggestions?

only discus really, any fish big enough will eat another fish in almost any circumstance. Giant danios would be bigger than everything else and active but not quite so big as a chalceus.

have you kept pink tails before?

Crossocheilus reticulatus, get about 7/8 inch and are algae eaters if I remember correctly

I have heard of fire eels that are introduced at a young age and small size not attacking smaller fish that they grew up with, but I'm not sure if it's a for sure thing or if it's the kind of fish that would interest you.

never heard of something like that

Rasbora caudomaculatus (sp?)
Or greater scissor tail if you want to go with a small group. I have six and they never bother anyone

Pic, they swim a lot

 

[Hendre]

scissors are probably best for you TBH

These guys get six inches a decent sized school would look nice in your tank

I have Dennison barbs in with cardinals and rummies and they never bother them. My Dennisons are about 5-6".



Bala sharks would be another possibility.
