I have a one day break from school before finals start so I took advantage of this and the poor weather and did some maintence. Tested my mag which I do maybe 4 times a year. Spot on at 1410. Thanks reef crystals. Decided to take topdowns of a few colonies I have. All raw shots with no editing. Taken by my Galaxy S4
Hairy pink tabling milli
Tyree Microphalma
Ora ponape birdsnest (This one came out pretty crappy)
Finally my favorite sps in my tank. This is its true color to the naked eye and its consistent everywhere, not just from viewing top down.

I love that Millie
Thanks judeo. Nowhere near your collection but ive got about 30 or so highend zoas now in the frag tank and then those few (my favorites) in the display. Let me know what you like, maybe we can do some trading when things are ready.

Definitely, I am currently in grow out mode but definitely dude when the time comes!
Lol I just presented as part of my final for an animal behaviorist class and did it on clownfish protandry which was a cool topic for me. Im not worried about my other 3 except for organic chem but thank you, im sure you will be fine. Where do you go to school?

Are you on the new brunswick campus? We have a similar professor who is trying to give us all the exceptions on the exams.
Kyle, your comment about your animal behavior final caught my interest. I am degreed in Biology (and Chemistry), albeit 40 years ago. I also say this with ignorance because I’ve never looked into the voodoo magic that goes on with sexing clownfish. However, I never would have guessed it to be protandry (typical with plants and a few inverts)….I had been told that the young were actually sexless, until they flipped a coin, and someone lost!
Anyway, how did you tie in animal behavior and the flipping of a coin to determine sex? Is this sex determination thing environmental, age related, lack of presence of other males (or females)…..I’m curious in what you found….and please, the Reader’s Digest version with simple words. Thanks.

Paul here is some info: Sequential hermaphroditism occurs when the individual is born one sex and changes sex at some point in their life. They can change from a male to female (protandry) or female to male which is protogyny. Clowns are born male. And one in a cluster becomes dominant female, usually determined by largest size so this is essentially based on growth rate and then a second male becomes dominant male who reproduces with the female also determined by size. All others in the school or cluster remain juveniles. If the dominant female dies then the dominant male becomes female and the next largest male will grow at an accelerated rate and take the place as dominant male.There are occasionally 2 dominant males which is why you can sometimes have a triple binded pair. The clownfish males have latent ovaries that develop and dissolve the testes whenthey become female. This is why they cannot revert back
My paper was focused on two things. 1. How protandry is more beneficial to these fish than fish with born sex determination and an inavility to change it and also the external parasitic disease fighting benefit that their mutalistic relationship with anemones provides due to the nemacyst in their tentacles. I also performed 3 controlled experiments to test and back up these claims that both characteristics are not only advantageous to survivability of the indivual and species as a whole but also, ultimately for greater reproductive succes.
If you are interested in anything else, pm me. I love talking bio

the interesting thing is that there seems to be more to it than just size. something else can also determine final status.
i got a pair of picassos, and they were similar in size, with one being slightly larger, but both being male-sized and not female yet. but the larger one hasnt grown, and the smaller one grew out to now be slightly larger, and is dominant - bullies the other one away from food, and the other one does the twitchy submission gesture. so the smaller one is becoming the female.
of course this is anecdotal - not trying to claim statistical significance.

See you are comparing it to clowns in a home aquaria which act and adjust differently than a natural cluster. I had to be careful to avoid these biases in my report.
Also being Picasso, I bet they are tank bred
