My LFS is selling a 7 gallon acrylic cube with a built in wet/dry filtration system, heater, light, sand, and everything you need to get started except for fish and water for about $238 (special deal for me )..... I'm thinking of getting that, putting an anemone in it, two clowns, 2 shrimps, and a crab.... What do you think? How does the price sound? Any advice? Thanks
