No but I think pedro posted this so his online prices might be cheaper than in store prices. Pedro would be the owner and runner of aquascape. There's also alex too but I'm pretty sure pedro posted this ad. If you really want them I would call back and get the name of who you're talking to/maybe ask for pedro/alex and either way tell them you saw an ad online for them for 125.00 a peice.
It would be vary hard for someone short of a cichlid expert to sex them at that young into pairs anyways because the only way to be sure would be to vent them. And although pedro is cool, I don't know if he would be confident enough to sex them as sexed pairs at 3"..
