I did it! (Possible calathea medallion)

I did "the chop" to this unidentified calathea a month or so ago because I had forgotten to water it and give it sufficient light. It was down to just a few crusty leaves. The old me would have just thrown it in the compost. I moved it to bright indirect light in a room that I'm in all the time so I can't forget about it again. And look what I found today! Any suggestions? I'm afraid I'm going to over or underwater it, etc.
