Yes, up the size and frequency of your wcs, and when you do them, also do a good tank cleansing job - good substrate vac, complete glass walls wipedown, and removal of the oily slick on the water surface. You could up the temp a little to stimulate their appetite, and add a little salt for those frayed fins.
Is your filtration in good condition & operating well ? What media are you using ?
Let us know your params when you have done your testing.
