Hi, sorry for the title but my yasha goby is stuck in the back of my aio in the pump chamber. The construction of the aio is dumb in that it looks like this (attached). He is hiding underneath where the other chambers are. I have removed the pump and put my heater in the display with an airstone to keep oxygen flowing. Can anyone help suggest a way to catch this fish? I don’t want to put the pump back in until i catch him so he doesn’t get shredded
