To OP, did you mention this was your first tank? If so, my advice is to buy cheap fish until you figure out how to keep them alive. Although fishkeeping isnt hard persay, it can come with a learning curve. Ots one thing to lose a $1 fish, quite another if he was $100.
Agreed. I've been keeping fish for around 10 years and only recently have I gotten the experience and courage to shell out for more expensive and rarer catfish.
