How Long Will It Take

[black molly3]

how long will it take for my featherdusters about 4mm in size to get to a decent size. at the moment i am feeding them invert food as it is stapel food for them. how long will it take for them to get to about 2cms.
thanks

Depends... Some species of featherduster do not grow very large at all. They may continue to grow their tubes longer and longer, but they dont get much wider or have a much wider crown. Regardless, their growth rate is very slow.
