Hippo playing with fire!!!!

[fresh]

Ok, well not exactly

My hippo keeps swiming SOOOOOOO close to my RBTA!!!! I am talking 1/2 cm or even less from the nearest tentacle!

It has gotten so bad, that I keep watching my tank just so that I know when to get up and stick my fingers inside the BTA's mouth to fish the tang out!!! I don't look at my tank any more, I only look at the tang and "wait" for him to be caught by the RBTA's tentacles!!!!!!

Anybody has this behavior in their tanks?

Do tangs know that BTA = DEATH?

My hippo is only 1.5" long, and I got him when he was less than 1" long, so I have a feeling that he never saw a BTA before and doesn't know that it will eat him if it catches him... any thoughts?
