Read the stickies on this forum for solid info. It's done me a world of good. Corns are easy keepers, forgiving of newbie errors, stay a reasonable size and weight, and come in tons of colors and patterns, in all price ranges. Understand you're looking at a 20+ year commitment. The most wonderful things about corns are that they are naturally inquisitive, get to know their person, and are capable of developing personalities. (Yes, they do have unique mannerisms and definite preferences.)
The most difficult thing with corns is to "know your limit; stay within it" lol ...so make sure you choose your color morph carefully!
