Aquariac- I want to commend you for listening to advice and opinions that you may not like in an open minded way. Alot of people could learn from that IMO.
Shameless plug for AC, RB! Seriously though, I agree that probably every bit of up-to-date information available can be found on AC/by AC members. However, it would be nice if when someone asks me a question in person about fish instead of saying "Go to AC and madly search the forums/stickies" I could simply say "pick up book X." But now I think I have gotten off topic so I shall stop typing.
Update: I've now found a home for 27 adult endler's, but I'm not sure what to do with the guppies just yet... I actually just decided to maybe try and breed my own "strain" (there are some hybrid males that are just starting to color up and they are GORGEOUS!) so do you think I should cull by giving the unattractive ones to an lfs for feeder fish, or something else? I already moved the 13 virgin females from that brood into another of my 10s, so that's 40 fish gone from the tank. (and yes, I'm aware that two ten gallons isn't a good breeding setup, I'm not breeding them yet, just preparing for it.)
