Recently started stocking my 600g and a big 7-8” Orange spotted rabbit was one of the first fish I added. I’ve been loosing fish slowly when they’ve seemed fine then all of a sudden they disappear. Yesterday I noticed my small fowleri tang swimming at the surface like a clown fish and breathing kinda heavy. I was just hoping it was sleeping or just acting funny like they sometimes do. He will sometimes swim upside down in the corners. Today I found him dead on the sand bed with 4 evenly spaced lines on his side. Wondering if that’s an imprint from the rabbit fish spines. . That’s the 3rd fairly expensive fish I’ve lost, first my small clown trigger disappeared then a baby sohal tang. Think I may be re homing a rabbit fish. Every thing started fine but lately I’ve noticed him getting aggressive towards my big 8-9” naso tang usually when they are eating off the seaweed clip. He turns dark black and white and throws his spines up and kinda angled his back towards him.
