Green BTA is not green??

[nanmer]

Thanks for all the info Bill! I have researched a lot and not been able to find such a great answer. I see pics of BTA and they are a nice green color, I was kind of worried. I have a 120 gallon tank and soon will be upgrading to 180 gallon. Each nem has their own area and after running around the tank for a week or so they have their special area. I have puffers and the nems eat what the puffers eat (squid, clam, shrimp, scallops). Family members take turns feeding, the kids love the sticky feel of the tentacles.
