false perculla

i have a groupe of 3 false percullas one is a bit bigger then the others she is about 2 in. how long will it take them to reach full size.

 

It really depends on how often and how much you feed them. I could be months, it could be years. It also depends on which becomes the female and male. The odd man out, if I remember this right, may remain unsexed.

 

yea i had 2 about a year ago and one hrew way bigger and killed the other one but once he dies she stoped growing, will she keep growing now that i added others

 

Doesn't really matter that you added two other fish. Growth is more dependant on the fish's nutrition, not the relationships they form.
If your old fish is the largest, it will have (likely) already been the female, and will stay that way. If you bought these new fish as a mated pair, than one of them will already be a female, and you can likely assume that there may be some fighting between the two females. Males can turn into females, but females cannot turn back to males. So likely, it will be your smallest clown and your pre-existing large clown that will end up pairing. If you bought your new two clownfish from a tank with many clownfish, then there is a possibility that they may both be juveniles, and not be either male or female. This would be the best situation, as the largest of those two will take on the male role, and the smaller of those two will remain a juvenile. Now if either of your male or female clowns were to die, the juvenile would step up into the male position, and the male would take the female position. Does this all make sense? I hope i didn't ramble (which I think I did).
