Congrats on the pods! Just a heads up, in a 24g, the mandarin would destroy your pod collection in about a week or two. They constantly eat and there is no way you could possibly keep up with their appetite in a 24g. Unless you intend to buy pods on a monthly basis from one of the online retailers.
If you want one, get either an ORA mandarin that feeds on non-live food or get a spotted mandarin (the green one with target-looking markings on them). They usually take to non-live food more readily.
