Retirement and forum shutdown (17 Jan 2022)
Hi,
John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.
I wish to thank John for his hard work in keeping the forum going.
With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.
I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.
If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.
I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.
I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.
Thank you
Darragh Sherwin
Today In The Fishroom~2/28/11 P. zonatus
He does his fair share of glass banging. I was trying to get a picture of hi hitting the glass. The challenge of course it to time when he will hit the glass. Generally by the time you see him doing it and hit the button...it's too late. I had to second guess when he was going to turn and strike. I took a couple dozen shots and got a few.
Here he is with his lips partially flattened against the glass.
My brother was visiting and commented on the fish's dentition.
Same shot only cropped tighter. You can see the small teeth along the inside of his lip.
The anatomy of the jaw is really amazing. We were discussing the difference between the positioning of the teeth in relationship to the types of foods that they eat...predatory fish having pseudocanines as opposed to the smaller teeth in fish like the zonatus. Here's a link to how the jaws of the fish work: www.amnh.org/learn/pd/fish_2/fish_skull/index.html
And a close up side shot to show the external structure of the jaw of the zonatus.
I wanted to get a better shot of the open mouth. Using my standard three flash set up worked well to illuminate the fish, but cast the mouth somewhat in a shadow. The Nikon gives you the option to shoot in commander mode and either add flash from the camera using the TTL function, on manual, or none at all. Most often I add a 1/128 power fill to the shot. For the photos below I use the TTL (through the lens) setting adding a nice "dollop" of light to the front of the fish...and the inside of the mouth.
The end result was a win-win for me. I can see how utilizing this new light set up works better for getting macro shots. If you consider the function of the jaw in relationship to the positioning of the teeth....you can see how they would be more efficient in scraping and rasping rather than that of the more predatory cichlids.
