What would cause zoo's to grow a long stem's?
Also what causes zoo colonies to thin out?

 

[Schadiest1]

zoanthids will have elongated stems if they are reaching for more light. however, some naturally have long stems.

as far as colonies thinning out, could be poor water quality, something eating them (like nudibranchs), etc...
