I have a BTA that decided to make his home the very back of my tank behind my main aquascape. Obviously this is not ideal since no one could see him to enjoy his beauty . I gave him a few weeks hoping he would move on his own but he is staying put. His foot is very deep in the crevice of my rocks where it is nearly impossible to reach in there to try and pry it off. I bought a small powerhead and started blasting him with flow in hopes he will come off but after 3 days of being blasted, he is still not moving and now I am worried I am just injuring him. What are my options at this point?
