We have a lionfish that has been very good to us for quite a while now....last week it seems he stopped eating....but he was very agitated...now this morning i find him on a plant. so i threw some food in the tank (95 gallon wave front) and he didnt move.....so i got the net and decided to see if i could scare him away or intice him with food (it likes the net now....thats how i got him to eat prepared food)but instead of moving he just floated around the tank not moving like paralized. He isnt breathing fast or has cloudy eyes....it just seems like he cant move....i checked all the lvls and they are perfect....can someone help me?!
