sounds like fun, i dont knoow many monitors other then ackies that should be kept in a breeding group tho, especially with groups of 1.3 or 1.5, simply because well youd need a small island to properly house em lol.. when u get into monitors like blackthroats and argus (which im especially interested and patiently waiting to keep) they need really large enclosures and to my knowledge are territorial. plus require alot of funds to properly house em. if you could maby put the breeding off, itd offer alot of more options. like if u have the space a blackthroat, a argu, or even a tegu.. they can all become very good captives and pets. the tegu is a around the same size as the other two but requires much less space at only really needing a 8x4x3 eclosure opposed to the argu needing a 12x6x4 and the black throat needing atleast a 10x6x4.
