Chaetodon Mertensii-How hardy are they?

I'm looking at getting one from liveaquaria. Does anyone have experience? Are they easy to get to eat? Prone to disease?
 
I don't have Scott Michaels book with me right now but I remember reading that there are two color forms. I think One is from the Pacific and the other is from the indian ocean. Hopefully I remembered that right. I can post what it actually says soon if nobody nobody backs me up.

you got it right on the nail.

pacific and indian colour forms of the same fish.

this fish is also synonymous to Chaetodon madagascarensis.
 
I'm surprised one with a crown and one without would be considered the same species... that's more than just a shade of yellow/orange variation. Very interesting!

They are differentiated. Similar to Lyretail Anthias.

C. mertensii is pacific (yellow & no crown), whereas C. madagaskariensis is Indian (orange w/ crown).

Look at the locales of the pictures of the crowned fish on the Fishbase page. They are all IO specimens, thus C. madagaskariensis. The eye stripe is also not continuous on these specimens, confirming even further that they are the IO counterpart and not actually C. mertensii specimens.

I am not sure why they're on there. One of Fishbase's many errors.
 
As far as care, they are easy to acclimate & feed compared to some of the more delicate BF species.
 
from scott michael's book.

madagaskariensis was once considered distinct but is now recognised as a synonym for mertensii. IO variants have eye bars that do not connect to each other and have a crown. PO variants have complete eye bar that connects on both sides and hav a darker smudge where the nape is.

both same species.
just diff variants.
 
It's a shame I haven't seen the IO specimens for sale much...they are very pretty!
 
yah the IO ones look abit like xanthurus but are much yellower.

my fav from the complex is paucifasciatus but in the recent years they've seemed to have became extinct!

I have a very VERY old little marine tank handbook I have from Tetra (ie so old it says to start your tank cycle with a small handful of potting soil :lol: ). There is a picture of a pair of pearlscales that I always loved... one had orange, and one yellow. To this day I could never figure it out...I always figured it was a camera trick. Now I know!!

Oh and tell me about it!! I've been looking for a Red Sea specimen for years now. Nuthin'!! :(

Sorry to the OP for the hijack. :o
 
anybody reading this have either in a reef aquarium?

Easy to feed butterflies, I'd imagine they would have a feast in a reef tank.
I've had a few madagascarensis, but only in a FOWLR system.
They were hardy flies that were easy to care for.

(I caught mine with a tiny fishing hook off our local harbour entrance, they like pink prawn bait:dance:)
