My ADF's (2) live in a ten gallon with tetras. I bought the sinking frog pellets, but I've never seen them eat any. I've seen them eat bloodworms, but I've been advised by someone on this board not to feed my tetras bloodworms more than once per week, and they eat them when I try to get them to the frogs. Are the frogs eating and I'm just missing it? Is there anything I can do to assure that they are getting fed?
