Harley was going after food at the top that had floated over there, it was dinner time. Half the tank is baffled for the moment and the other has the bubble bar, which won't be so strong after the plants grow in. Plants got put in yesterday, about 14 new species which are all small. Removed all the plants that had grown in for the new ones. He's fine so long as he doesn't get so close to the bubbles like that, although I think he's also swimming in it on purpose a bit. Plenty of other room for him not to be going there except because he wants to.
