Couple of papers, one showing some benefits of fish inbreeding, one showing some of the pitfalls.
All depends what your doing with the fry,

sometimes you cant get around it though, in Australia all of the electric yellows came from 3 fish that were imported in the 80's. because of this is very common to find bad blood lines but there is also some pretty good ones
Unfortunately approx. 15 yrs or so back there was also some idjits in AU breeding yellow labs with red zebras, which produced yellow labs with no black on the fins. Many people at the time assumed that they were pure, so no doubt those genes also found their way into at least of some of todays yellow labs being sold on the island.
Here is an older discussion from 2012 regarding inbreeding in fish, which started out about festae, and then went off in a more generalized direction. I suspect this was the thread that you guys were referring to.

From that 2012 discussion, I posted a link to the following. Damian (Number 6) summed things up regarding inbreeding fish quite nicely, in every day layperson language.

Whether inbreeding is bad or good, I believe its an illusion to think if you buy from two different LFSs in your area, to believe you are getting stock from different genetic lines. Many LFSs get stock from the same large companies, or from local breeders.
When I was breeding haitiensus, after a healthy female was grown out from a group, I went 100 miles to Chicago to find a male. (This may also not be out of the realm of close kinship) But it was older, so at least not immediate brother sister match.
The genetic weakness i found in the groups I had purchased previously lead me to believe (rightly or wrongly) that I needed to be assured of a totally different line as I was able to get, to breed with my female.
This later became my preferred pattern with other species, if I got a group of whatever species from the east coast, I found it personally satisfying to order another from the west coast if possible, and combine the 2 groups to grow out, and select mates within the mixed group, especially if some were wild caught, and some not. The influx of genes from the wild caught groups were (at least in my mind) a good mix.

Very good post, it helps to know which supplier your fish come from as well, some fish stores use one supplier, others use multiple suppliers.
