I got couple fauls perc in my tank and I finally decide to purchase a BTA for them. My perc shows no interest at all to the BTA as they always hang around my powerhead. These couple days I found my cleaner shrimp "dance" on top of the nem and seems to me it is picking up "stuff" to eat. Could that be possible the shrimp just eating the dead skin off the BTA if they got any? I don't see the BTA react to the shrimp at all, still got bulb tip and not retarcting. I am just afraid the hungry cleaner shrimp consider the BTA a nice beefy meal.
