Another month has passed and as usual, here are more pics of our hobby/sport combo that we are using these here and there this time to promote our Brisbane marine aquarium society (aandtsociety) that can inspire interesting conversation at times about the very old Brisbane area (only) clubs activities.
All of these pics we use are reduced from between 2 & 3 thousand K down to between 8 to 30 kilobytes more or less for good reasons, so the result is low quality for viewing but very nice originals.
This is the link to all our collecting trip underwater photos that we started compiling just a few years back, there isn’t just collecting and underwater pics here, it has most everything on affective collecting, planing of ocean sports and our web pages, one on most dive sites in the South east of Q and another on how to collect properly, all links and information is up dated each three months on all collection laws on fish, general inverts and (legal) recreational coral collecting in the south east of Q and all aspects of how to affectively collect for local hobbyists to the Brisbane area and understanding the oceans functions a little more as well.
It wouldn’t be of any interest to others out side of Queenslands South East and this area is not totally open for very good reasons.

On some trips to collect or to just take photos there are often a shark or two, this is interesting to some and that’s why our shark thread is included, personally the aquarium species are far more interesting after you have seen some sharks.
In the past, before we had nothing in the way of cameras included on trips, there would have been other shark photo opportunities for pics to be taken, maybe in the near future we will get a few more photo opportunities for other species again, they are quite often around, just good at sensing us from a distance.
The last time we saw a less common shark was a trip at the end of the whale season that usually attracts the big ones to here, this one trip was three years back, a white at around 8 feet and a sizeable bronzee swam past a couple of the guys, (dirtying wet suits of course), and the next day a guy we know well, that knows another guy well educated on sharks, obviously we could not clarify who either are, gave him a head of a shark for its jaws.
This shark had been bitten off from behind into the gill area, possibly not side on from what he described, the whole two thirds went in, maybe in one bite maybe in several, he said is most likely from how it looked and was bitten off this 8 foot shark that may have been seen the day before and the experienced person on sharks identified the bite pattern as a (quite large) white pointer!
This happened just off cylinders beach at straddie!
They are out there and numbers are increasing as we all knew would happen once they were protected, we just have to be very careful and get in at the right times and in not so dirty waters and definitely not wearing wet suits that resemble seals in to many ways as is sold mostly these days.
They proved what wetsuit patterns help discourage attacks by most sharks back in the eighties.
This link is to the more common sharks in the area, there still isn’t a pic of a wobbie there yet.

Clams seem to be very popular with some hobbyists and I must admit they are a sound purchase being very easy to keep in the aquarium, so a link to our photos on some in our area of these is included and at two sites we visit regularly we see hundreds of them in 1 to 4 metres of water, some young ones as small as a twenty cent coin in size and the biggest at around a foot.
It has also been educational to watch the speed at which individual clams grow when each time we go to a certain site and check on a particular clams growth, one in particular, a favourite of opal colours I first noticed at thumb nail size that I have been checking for twenty four years now, had no idea they lived that long, it got to documented full size quite fast.
In this link are the more common variations of clams from the many we see out from Brisbane.

This is our thread on the more common tubeworms seen on our collecting trips here in the South east of Q

Some of the tubeworms collected.
Some of the tube worms collected over 5 months are in this tank.
These have special needs to survive for the long term in an aquarium and have the potential to breed very well in a properly developed aquarium.
If not treated properly to begin with as they normally come sold with the main predator on the tube in well hidden egg form or a juvenile killer of these in at least one tube on purchase and has already started eating the tube worm from with in the tube and once in the tank you will never get this predator out, plus most live rock comes with this predator in it!
Tubeworms are more dependant on phytoplankton/algae based foods and many other conditions to get years out of them and multiply very extensively with a lot of trouble.
A homemade food copying similar to phytoplankton substances for these is very simple.
They also have no specific life span, if nothing kills them (they are a very popular food source for many fish and inverts) then they can have a potentially, very long life span.
From June to October is quite a good time of year for cray hunting while collecting; these are just a few pics of this part of the sport/hobby combo.
Hepatus blue surgeons are very popular in the club member’s aquariums and this year blue tangs were extremely common on our trips, on most trips where we would see 100 plus we would have taken one or two, always lots left behind for the commercial guys, other recreational collectors and natural culing.
They are brought along after spawning every year with in the plankton and leave it to inhabit our waters and else where along the ways, just some years they drop out of the plankton in huge numbers compared to other years, the ocean normally works on a cycle of 7 years for the little more unusual happenings!
They are fun to collect when in 15 to 30 feet of water, but I don't keep them in my reef tank, the other members do!
I have some in my tubs that are pets and used for testing foods, all kinds of things and live with no substrates so there is near to no chance of white spot!
There have been quite a few hundred at most sites; these are just a few underwater from one site.
A couple of blue surgeons collected, one of them is in the following aquarium.
Here it is just over two months later in a member’s aquarium.
Purple acro underwater in rock pool.
Purple acro in tank two months later.
One of the acans collected.
Acan in tank three months later.
The system supporting the aquariums fish and corals that follows does not use a skimmer or live rock or any type of substrate, it is run by a natural waste management system.
Copper band (chelmon) under water before collection.
Copper band collected.
Here it is in the aquarium 3 weeks later.
Xenia in tank 4 months later.
Sunburst coral, leopard wrasse and mimic tang collected.
A nice sized meleagris leopard wrasse collected, once it gets to big, which will be a very slow process in such a small tank, a member with a bigger tank will want it, nice fish from past experience, big or small.
Sunburst coral, leopard wrasse and mimic tang in the tank 5 months later.
They are well trained for photos.
A couple of corals collected.
These corals in the aquarium amongst others 5 months later.
Latezonatus amphiprion Underwater
The same latezonatus collected.
This is it in the aquarium over 5 months later.
With the right conditions, a very easy wonderfully natured semi temperate amphiprion to keep in a reef tank.
