Do you have the leafy's? If so do they also eat the krill? I think they are my most favorite ocean critter. Neal says I couldn't work at the aquarium because I couldn't pass their tank without stopping for an hour
I find it a little strange that all the aquariums that keep them have a tank that contains only artificial plants. I mean ONLY these plastic plants, nothing else. One of the write-ups said that, "pound for pound" they are the most expensive animals to keep in the aquarium. I don't think ours have done well though as I am sure there are fewer of them than I saw during my visits last year. I don't know what makes them so difficult to keep and why a more natural environment is not used. Oddly enough, they are one of the critters that made it through the flooding and subsequent power outage in New Orleans.
