Top 3 most aggressive aquarium fish.

Neon green Danio Glowfish. A genetically modified species which attacked its tankmates with overt territorial displays of aggression.

Chinese algae-eater. Had the odd habit of latching on to the side of goldfish in lamprey-like fashion and feeding on their protective slime coat.

Rosey Red minnow & flathead minnow. These would use their blunt snouts to ram tankmates. Highly territorial and aggressive fish.

What is your experience with aggressive aquarium fish?

I had Oscars. They will eat any other fish in the tank not bigger than them.

A friend had aquariums and introduced a small Oscar, and immediately lost half of his other aquatic population in a matter of days.

Mature Angels are no joke either--they can be quite nasty.

Never been a fish-guy, but I've had snakes before.

'I've had snakes before'

now there's a pet with personality!

of course, being snakes they all have the same one

but at least they're consistent!

I had a brute in a 200gal tank a few years back that killed every other fish I put in there. Other bass, sunfish, crappie, oscars, whatever.

We have African Cichlids in a large tank and South American Convict Cichlids in another. The large tank has to have a confusing number of cichlids so they do not start fighting to the death starting with the 2 most mature on the way to last man standing. If you have little ones mixed in they need lots of hiding places.

My Burmese Python was a big, docile lover. My Reticulated Python was rather aggressive with an attitude. My Red-Tailed Boa was an attention-hound.

I knew you'd say something like that ; )

snake 'personalities' are feeding characteristics of the different species

the perception of 'feelings' in lower order creatures are human projection of their own onto them aka anthropomorphism. it's been thoroughly and scientifically explored

but I'm sure you know this

My daughter is acclimatising her first proper fish tank - 90 litre tropical.
But we are looking for friendlies, not killers ;-)

Peaceful is good. Here is a list of 35 peaceful fish. 3 spot and Pearl Gouramis could be a good choice for size. The Celestial Pearl Danio sure looks pretty. I don't think they were around back in the day. Dwarf gouramis are also very pretty. I've always liked Rams. There is a suggestion for the Bolivian ram for peacefulness. Pretty sure I had German rams which are not aggressive like the other aggressive fish but may be more aggressive that the Bolivan?? Worth looking into.


If you wish the sympathy of the broad masses, you must tell them the crudest and most stupid things.

Where do you get the idea that the neon Danio is an extreamly aggressive fish. They are being described as peaceful to mildly aggressive. "They are shoaling fish and great for community tanks." Like rust, misinformation never sleeps.

Thanks a lot.

She'll be buying fish next week.
Unkillable ones first. Then progressing to fancier ones......

I once visited a couple who had a salamander in the tank. They said it was much better than fish, in that it exhibited some personality, and being a low activity being, might not have minded confinement as much as an animal running higher energy levels.

They took him out and let him walk along the arm of the couch, and he seemed to enjoy the attention, or maybe he was just fully panicked and trying to run but moved so slowly I couldn't tell.

There are no un-killable fish unfortunately. It's a very enjoyable hobby but fish dying is part of it. If I ever am in a situation where I could get back into it I would be thinking seriously about keeping non or minimally aggressive fish myself. Have fun.

"Where do you get the idea that the neon Danio is an extreamly aggressive fish. "

From direct experience, it was one particular individual that was extremely aggressive with its tankmates.

Platys have been the best overall in terms of demeanor.

...don't make it to an aquarium (around here). They are immediately transferred to a frying pan. But, yes, they will eat anything/everything.

Nasty fish. You see babies in stores, aggressive, and the adults get quite large too. Locally they've become a nightmare. Some escaped/were let loose in the wild and they are eating everything they come across.
