What does F1, etc., mean?

I see references to fish being F1, and so on, and I assume from context that that refers to generations of wild fish bred in captivity, but I cannot find any confirmation of that assumption. So, is that the case? I believe I have also seen references to V1 and so on. Same case?

Thanks.

you are right about the F1 and so on......F0 means that it is the first generation of the fish caught.....F1 is the first spawn of the F0....

as far as the V1 i have no idea...i have not seen that before

anything else?

Thanks, cLateralis29. I thought that was the case, but I'm new to this and thought I would check. And maybe I hallucinated the V1 as I cannot find the reference again.

Anything else? O, no doubt there'll be more questions down the line as I settle on what kind of fish I want to keep. Right now I am enjoying the gift of a young male Montezuma swordtail, so maybe I'll end up keeping those fish. He's quite handsome. I have also been offered a male and six female green swordtails, but I haven't decided whether or not to take them.

Which reminds me of another question: Does "flock breed" mean keeping a species tank that replenishes itself over time? And is that the same as keeping a "colony"? I think the answers are yes, but again, I want to doublecheck.

Again, thanks for your reponse.

i have always heard of it as a colony....just breeding the single species in a single tank...added a few ti the tank and eliminating some of the ones you dont want....kind of like building a group of all the best of your spawns

the term flock breed is new to me, i havent heard that before.

hope this helps!

And thanks again for your answer. If I encounter the phrase "flock breed" again, I'll put it up here for you to take a look at.

Cheers.

Flock Breeding relates to livebearing fish that do not predate upon their young, or do not predate overly on their young.

When livebearing fish do not predate upon their young, the fry can be raised in the same tank as the adults and this method is called flock breeding.

Look at that! I'm a flock breeder and didn't even know it.

Yes, then we are all flockbreeders - or at least most of us are Wink

So can we say fish of a scale flock together? OK, I'm groaning at that one myself.

Cheers.

Awful. Truly Awful.

Very Happy

. All to often our starter stocks of Goodieds are just one or two pairs which may not flock breed like other goodeids, and if ones initial stock is only one or two pairs then even if they are normally a placid fish they may then aggressively defend a territory against all comers. But persevere and take the females away to a birthing tank until the fry are born, then remove the Female back to her own home when she has finished dropping. When they are born have ready a new tank to set up your multi-generational colony in. Then after feeding the fry up separately for a week or two move the fry into that multi-generational colony. After putting them into this new tank just keep adding successive broods to this fry tank, thereby building a multigenerational group and in this way you may find that the fish in this tank will become so used to seeing young around that they take much less notice of them. But don’t go thinking that the brood sizes are dropping when you see only 5 or 6 new fry appearing in that tank that’s just natural selection or survival of the fittest is taking over. So you see setting up only multi generational tanks can happen if you are lucky but now if it doesn’t then you know how to get around it, however do not over crowd there tanks once they are adult. A predominance of live food is recommended which can include baby brine shrimp, blood worms, HBH Super soft with Krill and glass worms. Flake food can be offered from time to time. Feed at least two times a day as they can be quite gluttonous and this could lead to squabbles breaking out.Hope this helps some one
