im sorry but in my fish keeping expierineces ,healthy fish dont bump in to anything .i mentioned selcon and garlic as preventative measures ,why would he not want to fatten him up and build immune system ?.
fish swim all their lives .i consider them masters of swimming under water ,im not doubting your fish is or isnt crazy but i would keep an eye on him
