at least brevis have piranha-like pack mentality so there should not be much issues with keeping them togetherEasy there boys. I've decided not to keep a single dorado. Went for african tigerfish. Got three. Hope they are all or atleast one of them is a brevis
Batfs/brevis are very rare in the hobby though..
Very much true. But i wager they are easier to keep than goliaths, at least based on tank requirements.
Yes they are easier to keep but nastier than goliath. Highly aggressive. Even took the fin out of my bigger tinfoil barb. Lol
aggressive behavior can at least be compensated for, tho i would recommend keeping the three of them in a separate tank from other fishies.
I understand this is now moot due to your plan change but thought I'd still throw in my few cents, even if for the giggles.
IME my only dorado hasn't been one of the most horrible tank mates but it can be choosy in who it targets. I don't think it has ever been any of our catfish. Our experience including any notable tank mate interaction is described in detail here: https://www.monsterfishkeepers.com/forums/posts/7764972

M Mister-Blister Welcome to the MFK!
I hope to learn from you and with you about your fish keeping experience for many years to come. If I may, just a couple of comments. It is the goal of MFK to spread helpful, constructive, and solid information, which is either originated from one's first hand experience or second hand but both must be supported as best as possible with visuals, links, details, write-ups, etc.
Anecdotal evidence is not in favor here at all and if given too much of can warrant a corrective action from the mods.
Taking your example for instance, if, as you say, you held in your arms a trophy sized dorado that you believe is capable of taking your digit off, photos would greatly solidify your words, while without them, most people would treat your words as just shooting the breeze. Almost no one in their right state of mind would NOT take a picture or a video at that moment.
If you read somewhere someone's accounts of what the dorados are capable of, proper links (and credits) to where this is documented would again ensure that people don't just disregard your input as anecdotal hearsay, emotional exaggeration, flashy statement, etc.
The second comment involves tact and politeness. When someone new on the block, only 3-day new, freely dispenses advice and comment to those of MFKers who have been keeping fish for as long as that someone 19 year old lived, and some 2x or 3x as long, you can rest assured this will leave a pretty bad and long lasting aftertaste. I am not preaching from a high horse but from my own experience. I really, in earnest have been keeping fish for only about a decade and used to come off as passionate as you are until I learned better.
Glad to have you here, amigo, anyway.
It would seem that there are many, or even mostly, hybrids out there of brasies and frankies or so Wesley Wong claims, if I understood him right.

The only reason i brought up anecdotal evidence is that the poster who was arguing with me seems to value that more than "info that can be found on the internet" while at the same time showing a massive lack of knowledge on the morphology of golden dorado.
Studies on the behaviour of these freshwater predators are readily available and always portray them as apex predators:
Juveniles of the piscivorous dourado Salminus brasiliensis mimic the piraputanga Brycon hilarii as an alternative predation tactic
In the district of Bom Jardim, in Nobres, Mato Grosso State, Brazil, there are clear water...
This study also points out that ‚30 cm long dorados hunt smaller prey such as schooling fish, backing up my assumption that their true aggressiveness only comes out at a certain age.
Older dorados readily take Brycon hilarii, species that can grow up to 56 cm ad weighs 3.4 kg, quite of a jump compared to the younger specimens menu list.
The global fly fisher also mentions them as cannibalistic:
Dorado | Global FlyFisher
Locally it is known as "el tigre de los rios", the tiger of the rivers, and Argentina's famed Dorado is a popular and sought after gamefish.
Dorados are often referred to as the River Tigers, with a pretty good reason too
While their teeth are not the biggest the well-developed jaw muscles might as well turn their jaws into a spring trap.
In my humble opinion, you have done a great job supporting your statements. Thank you. It makes me a bit sadder I had to kill mine off. Oh well. If I get the license, I will try again, this time with a good size school.
I have not found my dorado to be this bloodthirsty creature these links depict. It was not that big though, only 2 feet and 5-6 years old.
When someone speaks of aggression without any qualifiers, I personally would like to gain clarity first what aggression they are referring to. Predatory aggression can be mitigated by proper feeding and by choosing large and robust tank mates or the ones that are aggressive territorially or hierarchically. Territorial and hierarchical aggression is mitigated by a careful choice of tank mates.
In the example above, the Jibran (headbanger) crenicichla's territorial aggression is probably what overcomes dorado's predatory aggression or the known nippiness and otherwise nuisance behavior, it's hard to think about feeding when the feed is attacking you...
Anyhow, this is all fun and dandy but I think you'd agree that the no amount of reading and generalized considerations can take place or overcome a thorough, grounded, and long term firsthand experience. The latter is heavily favored on the MFK, is what I have been trying to tell you too.
