I vaguely remember someone telling me that you could actually have an aquarium full of beta fish as long as they were all brother/sister fish which were in the aquarium since they were hatched.
Does anyone know if that is true? If you have a breeding pair and simple keep the baby betta in the same tank, they will all get along and not have the normal fight to the death normally associated with multiple male bettas ?
Yes you could actually have an aquarium full of Betta as long as they were all brother/sister fish which were in the aquarium since they were hatched. Yes I know that is true because I have done it 3 times already. No you don't keep the breeding pair and the baby Betta in the same tank, at the very least you must remove the female. Yes they will all get along. There is no "normal fight to the death normally associated with multiple male bettas." Given the opportunity the losing Betta will flee.
You have to leave the male in to maintain order as the fry grow. The male fry usually won't fully develop their fins unless they are separated. ...
No you don't have to leave the male in to maintain order as the fry grow. That sounds like a child's bedtime story or some John Lennon song. Male Plakat fry fully develop their fins regardless of whether or not they are separated. I can't speak to the long-finned variety, I've only bred them to use their eggs as feeders.
I've heard lots of stories, but haven't seen much proof that it works over time. ...
Then why don't you try it? I'll warn you though, the more 1st hand experience you gain the more you'll realize that this Internet thing is increasingly becoming awash with armchair experts regurgitating hogwash.
The fact the breeders serape males (and even females sometimes as there are more aggressive ones) while still fry/young juvies to individual cups/jars/whatever is a good hint you should keep them apart. Why would breeders put out the extra effort/cost of separating if they didn't need to? Because trust me, they would not if they could keep them all together instead, would save sooo much more time, money, and space.. but that's not the case.. and breeders typically (speaking of breeding farms-massive breeding programs overseas) just want to get them grown enough to sell, they don't care about comfort of the fish, just keeping it alive.
Not true. Read the last 9 paragraphs of the following webpage: Siamese cyberAquarium, Types of plakatthai
Yes it concerns Betta smaragdina
specifically and not Betta splendens
, however it can be applied to any of the 7 species in the Splendens
complex, which are all interbreedable.
