How close in a fishes lines, can they be bred. I guess the question is, is it common to inbreed fish or should you keep more than one pair from different lines to keep them pure? even know somewhere in the begining, every species there is inbreeding.

with bristlenose you want to out-cross. they are already inbred enough. The process of inbreeding for selective traits is a very tricky process and is something that requires a lot of time and research. I'm a aquatic ecologist and have spent a lot of time working on population genetics and I spend a lot of time and money making sure that my breeding pairs are from wildly different lines. I import my breeders from interstate to make sure they are different.

As with all species, siblings can breed, The thing is, they shouldn't. as a responsible fish keeper and breeder, you should make sure they don't.

i agree with Doug 100% on getting your brood stock from diff. places. the super reds i just bout are 2 males and 4 females but they are from 3 diff countrys so i will be running 4 diff blood lines so when i sell a pr of breeders they will not be any blood relationship at all between the male and female

Yes agreed on that, my pair of L144 where definitely unrelated but even those I have just split up as I dont know of anyone else breeding them locally and have sold around 200 or more fry to local shop, thought it best they where seperated, Im currently have the female L144 mother with my wild caught LDA072 male hoping they will spawn, 2 of her dauers are spawning with a common tank bred male, the first batch hatched this evening !
