First off Jmedic25 thanks for referring me to the Newbie Pitfall thread. I should have read this before the hundreds of dollars I've already invested. It seems like the two things I've missed are the most important, cycling and a test kit. I took the LFS word for it and bought fish and a 55 gal the same day. I did transfer the water from my 20 gal to my 55 transferring the bacteria. My water is at a constant 78 degrees and I do 20% PWC every week. I have 9 african cichlids and 4 live plants in there. I have had the tank for a month and one fish is missing I assume it is dead. This week I added 4 fish to it making the total 9 and my pleco makes 10. All my fish seem healthy and fully colored. Like everything else I do I jumped in head first without researching until after the fact. I just put too much trust in my LFS thinking them the "experts" I sell paint for a living. When that "guy" comes in every winter and tries to buy an exterior product, I always try and talk them out of it. I can make a quick buck and never turn back. I consider myself an expert and gaining the customer's loyalty through quality advise and service is more valuable then 1 gal of 36 dollar deck stain. I feel cheated and mislead. Is there anything else you guys would recommend me do to ensure my fish survive my blunder?
