Hammer Growing New Heads?

[Ballman17]

I am assuming these are new heads forming? I am having trouble finding good pictures of similar growth.

I also read on a post where the existing head would shade these out and cause them to die? How would a hammer ever get new heads if that were the case?

Thanks all!

Those are new heads, however they usually never really get that big. The main way hammers grow is by splitting their existing heads. The 2 main heads were one head at one point before it split.

hi , yes new heads, some may get shaded out ,but for the most part ,will survive,
nice pretty "rare" to see in captivity, but it happens...

No doubt and not dependent yet on light, flow, etc.
