My blog will get better when i get home

Its kind of empty and not finished right now.
Good reason to be nervous. I'm still nervous with new discus even though i've kept them for years now. Being nervous keeps you alert. Discus are fish that literally will let you know when something is wrong. There are so many signs they send off to you. A fish like a tetra would not send the signs.
You're plan sounds good with the existing tank, just make sure you got all of the bleach out. You're water sounds good as well as your maintenance schedule. Though maintenance goes hand in hand with feeding so it kinda depends how much and what you feed. I would not put angels with discus. Yes its possible but angels will usually out compete discus for food.
Are you planning on a planted tank or a
bare bottom tank?
To me, discus keeping is very simple. The phrase Keep It Simple Stupid is true here IMO. Mine were all kept in a bare tank, with a sponge filter, daily or every other day WCs, 3 feedings per day, and i used water out of the tap straight into the tank. The most important thing i can stress here is to get healthy fish to start. If you start with healthy fish they will be much more resilient to mistakes you might make and it will make the experience so much better. Remember, you get what you pay for. Going with the local breeder instead of the LFS is a great move. I order all of my discus online and have them shipped into me because i trust the source.
Let me know if you have any other questions or concerns. Or if you need some help finding/contacting a breeder/supplier. The discus world is quite small, almost to where everyone knows each other, so everyone knows when they find a good supplier and a bad suppler.
