Aqua creator, Aquariscape, Tanknology, look at your preferred clientel and gear your name toward those people. if you want to stick to highend reefs in doctors offices, use the word "reef" in your name. If you end up taking out a yellow pages ad, a name like "Reefscape" should keep people with a 10g guppy tank from calling. There is definately money in maintaining 75g cichlid tanks, its easy, you suck water out and put it back in and maybe bleach the fake plants, if this is your style then call yourself something more generic.

Good luck to you (unless you come to Austin :angry ) and kiss your weekends and personal life goodbye.
