Our female was biting for a while too! Acutally seems to have calmed down some since we got the nem. She would bite my husband all the time, but she's never attacked me so I've started doing more.
We usually have our hands in there for feeding time - we have sun corals - so she has plenty of opportunity to bite ! She even knew to bite him between his fingers, where the skin is more sensitive!! Sneaky little girl.
Before they weren't seeing the turkey baster as a food source (they would attack that too, especially hated the green topped one!) but the other night I noticed that they gently go up to it and try to take the food! They started making that association after we introduced the nem, we were feeding that and they caught on I guess.
These are such neat little critters! Glad to be in the hobby!
