You really need to scale back and learn how to handle a small tank with few fish. Sorry for your issues, but they are basically a result of you going against most all advice, rushing things and being impatient. You need to slow down...step back and rethink your position. You want to be a breeder. No way would I purchase from you if I had read your threads here. Not being mean or rude..just a fact from my perspective.
If you can't keep your sig current....how do you think you will manage a business? Book smart doesn't equate to understanding lefty-loosey, righty-tighty or which end of the screw driver to use.
