have you been keeping his tank salty and doing alot of WCs? his tail looks now about like my fh that you saw the pic of. well after all the fungus went away. if it is going to grow back, you should start to see some growth in a week or two. i was shocked when mine started getting her tail back. i felt like crap because i put the JD in with her trying to get them to pair up. she doesn't have any pearls, but has good color and great personality. jd are one of my favorite pure bred fish so i thought that it would be great to have an fh with dempsey pearls. all i got was a half dead fh with all her fins chewed off.
