Hi guys, how are you?


I have 8 aces (3 falcirostris and 5 altus), 4 boulengerella maculata, 1 Ctenolucius hujeta and 1 H. tatauaia...and all my fishes are eating feeders only! I'm trying to break to a non-live food approach but without sucess (starving plus pieces of fish in a line). I´m thinking about a teacher fish. What do you think about S. brasiliensis as a teacher fish? I could buy a trio of ) 3-4 inches) dourados and keep until my fishes learn.


What do you think about that?

I've got my wolf fish on frozen tilapia and market shrimp. So if they are huge predators maybe a fish that will except the that will make it an easy transition.

Both species of golden dorado- the one you'll get are almost certainly Salminus franciscanus- are fast growing, aggressive, pugnacious apex predators. They are also fish that normally require teachers. I imagine if you introduced a trio, they'd absolutely dominate your tank. They'd likely outgrow everything else while simultaneously out competing everything else which will result in them likely killing everything else when they're bigger. They'll also end up killing each other over time.

I would avoid it.
 
My experience with dorado is that they will eat any type of food offered but I agree that they are way too aggressive for your tank. They would most likely hassle everyone and/or kill them.
 
Thank you guys..


Chicx..here in São Paulo we have S. brasiliensis, there are farms raising these fishes here and they are very cheap. 4-5 U$ each.


KNH...even smaller than my other fishes?


Guys...let me explain better: I just want to keep those dourados here just until they can teach some of my fishes. I never saw a dourado with problems to accept food and I can buy one already eating pellets in many LFS here. After that I will give those guys to a fish farm. How much time could last until my aces get the lesson? I really don know. But I don't think that a golden dourado will outgrow my tank in 2 months if I buy him smaller than my smallest kuda....and if he is getting large...I'll send him to a farm and put another tiny one.


Why 3? My intention to put 3 and not 1 is dilute some agressions between dourados. I don't know if this could work...but it is a idea...


My question is: a 3 inches dourado will kill my 5-10 inches kudas, 10 inches sabbertooth and 7-8 inches boullengerella and hujeta?


A Brycon could be a choice...but talking with some guys that have a brycon...they said that Brycons grows faster than dourados.
 
The size difference would help but they move nonstop and love to hassle other fish. Why not tinfoil barbs or silver dollars? Something nonaggressive?
 
Well if you can get them, I suppose it's worth a try. I, personally, wouldn't risk it however. Dorados have a nasty but very well deserved reputation.

I'd like to see some specimens of the fish that are for sale. All of the literature that I've read suggests that the frankies are the ones being farmed. You are right on the border of the drainages that support both species, so it could go either way. 100% of the farmed exports that make it to the States are frankies; if there is a cheap, ready source of brassys I know a lot of people would be interested.

At this point, I want you to buy some just so we can see what they are! lol
 
The Brassys we know up here are Argentinian Dorado. Didn't Brasiliensis take over for Maxilosus when lumping all the species together???? I'd also wager to bet we're talking about Frankies.

Anyways, I can speak from experience with little Dorado, I had many Frankies. To disperse aggression you'll need more then 3. By the time you get their inter-species aggression curbed there's no room for anything but them in the tank..... I think they would also make very poor teacher fish. They hit anything that hits the water and they do it so fast that after the other fish gather their wits from being startled by the Dorado destroying the food all that will be left is the smell..... Tinfoil Barbs or silver dollars would be a much better choice. Something flashy that will "peck" more at the food, and something that is easily out competed once the other fish figure it out.

Click to expand...

Maxillosus was a junior synonym for brasiliensis, brassy was the first name issued.

I agree that frankies are the more likely candidate for farming. He does live in a unique place that allows him to visit rivers that contain both species however. That is the one and only reason that I'm not writing off brassies as being impossible. I always try to keep an open mind lol
