this is gonna sound weird but we have this chain of general stores in the north east called The Country Junction Store, and they sell everything from movie statues to farm equipment, to food and they have a fish section too. and its always insane. they have sting ray tanks, and always at least 30 different plecos and an awesome aquatic plant section, long story short pretty bad ass fish selection. any ways my buddy called me up and said they got a really sweet high grade shipment of rd in my local one so i went there and picked out the smallest one out of the batch, and im glad i did~!
