Liveaquaria, imo, has fair prices. Yeah they are usyausu more than other places, but they have the two week guarantee, and they do quarantine Diver's Den fish , including a bath treatment.
This seems pricy to me though. They had "large" clown Loaches earlier in the summer. I really to say they had 5-6" ones for $130 each for a set of three.
This seems like less of a deal but I guess it is slightly cheaper for slightly smaller. Anyway, figured I'd post in case anyone was interested.
This is one area a LFS in Chicago has covered. They had some in this size rage for $35-60 when I checked in early summer. Most of the other fish are way more than online, including beibg more than Diver's Den.
