Hi. I just joined this forum so I can post a query about my catfish. Not sure what section I should use however so I just chose the most used one.
My Marbled Cats had a skin color change a few months after I purchased them and not sure why or what it is. They are perfectly healthy and happy otherwise. As you can see from the pics 1 of the 2 is much more pronounced. It looks kinda cool, but just wondering if anyone knows what it is from?
Thanks!

hey my fish got something like that. I'm no expert but from what I was told my fish has Hole in the Head Lateral Line Disease. He's been getting meds for it. It starts in the head and it goes on the sides of the fish.
So far I'm thinking it could be something else. <img src="http://www.repticzone.net/images/33266/dscf3804.jpg">
