When I had my pair of Lace Gouramis they loved Atisons betta pro so basically I fed them like they were a betta, and because I have Kuhli loaches they also used to eat Loach wafers. Feeding them was not a problem over feeding because they ate bottom dweller food was.
Hey, maybe I'll give that a try. I feed my betta Omega One: Betta Buffet. I think I'll try that tonight. My girlfriend recommended Seachem: Entice, while we were out tonight. If she won't take the Betta Buffet, I'll resort to the Entice.
