A LFS is downsizing and is selling its large aquariums. I'm interested in one of the freshwater 180g he has. The tank looks to be in great shape with no cracks or chips anywhere, silicone seals look solid, no scratches on the glass and its about 4-5 years old. His prices are $500 with tank and light ONLY or $700 for tank, light, 2 filters and a heater. There is no stand or hood at all. Whats your thought on these prices? This size tank seems to be hard to come by in my area unless buying everything brand new. Any advice is appreciated.
