I've got comets, shub's and commons in my tank. They get gobbled up quickly.

goldfish + 10 gallon = not a good ideaDo guppies go with goldfish? (If the gf's aren't big enough to eat the adult guppies?) The gf's would regulate the population and you'd still have guppies.
if u buy a few new gups every month or so the new genes would stop this id imagineOne thing to include: die offs from such a massively overstocked tank. May be minimal at first but within a few months of breeding there's going to be deaths.
I wasn't specifically talking about inbreeding (although that certainly would be a problem) more so that 1000+ guppies in a 10 gallon would be a horrible living situation in general.if u buy a few new gups every month or so the new genes would stop this id imagine
I have been free breeding fancy guppies for about 5 years in a 30gl tank.I picked 5 color types 1 male for each 3 females plus a few extra for a total of 50 fish more/less. They do pretty much self regulate.dead of winter I'm down to between 30to50 by mid summer I may have as many as 300. I do pull off the red ones and the ones with bad shaped fins and bodys. The females will hold male sperm for close to 6 months before using it to drop new fry
