Hey guys, I've had this mertens juvie for a few months now. Just recently noticed its tail having the wavy effect. It's not the bone part just the ridging. There's no visible scale lifting or anything. The lighting makes it look like there's white spots but there isn't. It feeds on a mix of the marinara mix and velvet rat. Has also had yabby and prawn. Filter gets cleaned every two weeks and water pH is also tested. Just looking for ideas as to what it might be before booking a vet trip. Any help would be appreci
ated. Thanks!
