That’s essentially what I’ve been doing, with one exception: I’ve been putting it in a cup and it only ate the one day. But I do have a breeder net, maybe that will be less stressful on it.The best way to know that it is eating is by putting it in a breeder net, and only putting a blood worm or 2 in the net. If it's still there a few hours later then it is not eating. The breeder net will also give it easy access to the surface versus the bottom of a 10g tank. When my SAL was 3" it ate every day for 2-3 feedings.
