Duncan help

[coolhandgoose]

It doesn't look like there's flesh left on the dead heads, they look empty. There are lots of heads in total still. Will they grow into the dead head?
I'm going to brush the Duncan's teeth as my little guy says every couple days to try and remove all the algae.

In theory the heads should heal themselves if not too pee'd off. In other words, feeders may start to emerge from the middle of those heads and go from there.
Can the Duncan be removed from the tank for a better algae treatment? Toothbrush isn't the best way to go IMO
