RE-Post: As well as observations

  • We are currently upgrading MFK. thanks! -neo
You also make a good point...but again, i don't think anyone have the right answer for this. it's just not easy to tell the different, every expert have to cut them up to see and ID the sex. This conversation will just through in opinion, but there is no fact on this. Everyone got a good point, but what is the true?
 
I have no clue, my opinion as well as yours are just that, opinions. I just thought it would be a good conversation topic. Im just trying to broaden my knowledge as well as see what other criticism others have upon my opinions. There is no right and wrong here just wondering what everyone else thought.
 
i don't really think that the subtle differences in color would signify a difference between male and female. the brandtii are found in a smaller area, so the i wouldn't think that the difference would be caused by locality either. i think that they just vary slightly from fish to fish, an example of that would be to look at multiple natts that you know for certain were caught in the same area or natts that you have bred yourself, they all have slightly different coloration, some of them are a fiery red, while others are more of a light orange color.
 
Thats also true.. The gold color can just mean that the fish is in better Condition. Or like with the natts could just be individual color or just signifying that the fish in question is dominant.. I guess i got a little ahead of myself, wishfully thinking.. But either way all your opinions are greatly appreciated , thanks for all the replies
 
i wouldn't call it wishful thinking, who knows... it might be fun to look into. the fact is that there is still a ton of stuff that needs to be found out about all types of piranhas, so if you wanna get a gold colored brandtii and a silver brandtii to see if there are any behavioral differences between the two, i say go for it. you have nothing to lose, because either way, you would have two beautiful fish. obviously to make a statement about brandtii species as a whole, you'd have to make observations on a lot more than two fish, but all ideas gotta start somewhere.
 
The problem is finding these fish in general.. The one I have now I obtained from a fellow MFKer. It was a steal, he didnt have the tank to house him at his current size.. I havent personally even seen a silver brandtii but they are out there.. i would also need a mature specimen, say over 6 inches ( just a guess ).. That seems to be around the size that the ones that are gold start to change ( correct me if i am wrong ) Then they would have to be housed in the same tank, same water parameters, same temperature, same food ( type and amount ) and same surroundings. Just to see if these would have any impact of said fish. Do you think that beeing able to see each other would make a difference? or should they be secluded? Any suggestions on this matter is appreciated i am contemplating tracking down a large silver brandtii and trying this out.. JoeDizzle's Spilopuera have inspired me greatly and would like to try what he has achieved with Spilos, with brandtiis.

so are you talking about eventually keeping them in the same tank with each other without a divider?
 
Like I said before, Wishful thinking.. Your fish have inspired me to try to do something positive with my fish. Of course I would document all the steps I take and the like. I wouldnt just dump them in the same tanks as many might think, I would carefully study each fishes behavior before attempting to do anything like that. I would keep them seperate and I would attempt to learn everything about the new fish, as I try to do with the one I already have. Such as temperment and how each one reacts to other fish in its immediate environment. Mixing any type of fish with the brandtii I already have is going to be a feat in its self. I would of course then go into trying to figure out different spawning triggers and things such as that.. I have never heard of any Serrasalmus sp. laying eggs in captivity but it may just because we do not know what triggers the fish to do so in the wild. I would never risk any of my fish without doing my homework first. I love my fish and take care of them as if they were my children. But If anyone knows anything about serrsalmus breeding habits.. I am all ears.

well s. maculatus have been found in small loose groups in the wild, which is probably why people have had success in the home aquarium, but it is still not guaranteed and i definitely wouldn't recommend that everyone goes out and tries it. as far as spawning goes, s. maculatus spawn fairly easily and have been observed spawning year round in the wild.

as far as cohabbing two brandtii, i would probably invest in a massive tank before even attempting something like that. i would say that in the best case scenario, it would still be like flipping a coin, no matter how much you observe them beforehand, there will be absolutely no way of predicting what will happen when they meet face to face without a barrier between them.
 
well that goes without saying.. i am well aware that all serras posses a nasty disposition.. seeing that they are scale and fin eaters in the wild i wouldnt expect everything to run smoothly.. they do breed, so they must tolerate each other.. even if its just for egg laying and fertilization.. i understand in the wild there are millions of gallons of water and endless water ways and visual barriers.. i am just trying to arm myself with as much knowledge as possible before i even try this.. as for the spilos i am interested to learn about there breeding behavior.. do they guard there eggs such as the fish in the pygocentrus family or do they show no interest in the eggs once they are layed?... all knowledge is useful
