I haven't personally kept jewels but when I was reading up on them I found this little blurb.
" Found in a wide variety of habitats (from river shallows to steams, oxbow lakes, swamps, and even costal lagoons), H. guttatus is closely associated with aquatic vegetation and is a forest-dwelling species. "
If you plant the tank while it it cycling and give the plants a month or so to establish then the Jewels shouldn't bother them. Just make sure anything that isn't attached to rocks has rocks around the base to discourage digging.
