Happy to hear she's eating nori..that's an excellent sign!
If you happen to have some Selcon, you might want to try soaking the nori in it before feeding just as an extra boost of vitamins. I do this time to time to help supplement my fish's diet.
How do you feed your nori? I tried the algae clip that came with one of my packs but found that too much would tear away and end up going into the overflow so I switched to a feeding stick ( a piece of 1/2" PVC). Just wrap a sheet around and and hold it on with several elastic bands. Now there is very little waste and my hands don't get wet
I drop in the stick before leaving for work (well before the fish wake up), so my fish have something to nibble on until I get home for their regular feedings.
