The festivum (if starting out small)(and depending on what species) . should be OK until it reaches adult size, but even then as adults , they are not very adept at predation. (they are more insect eaters)
Some species of Mesonauta (all known by the commerci monikerfestivum) (there are 6 described, and another 2 in limbo) reach 8" which will outgrow a 60 gal, Some species (mirificus, or insignias) are said to only reach 4-5" and better suited for that size tank.
