i bought some feedder fish this morning and placed some in my tank for my knife fish... the lights are off cause my knife fish won't feed with them turned on, i noticed a fish swimming vertically at the side of the tank trying to fight the current from my filter. i ignored it and thought that it's just a wounded feeder, but after half an hour i checked my tank, and saw that the fish stopped swimming and was actually resting on the glass, it has fins under the belly so it could hold on. i took it from the tank and placed it inside my small pen, it 's face looks like a goby, the head is round and has globe fins, initially it was dark in color , but when after an hour it turned to light brown with some black markings... any idea what fish is this?
