Cold water marine...

I forgot about your importation regulations.....but, there still must be quite a few interesting,colorful things in your own waters to collect. Does anyone on this board scuba dive ? Tidepool collecting is fine....but diving will open up more opportunities. I collected the anemones in my tank at around 70 ft (24m)......I'd never find them in a tidepool. It took me about 10 minutes to carefully detached each one from the rock. Maybe visit a local dive shop and find out what's out there......especially invertebrate wise. When I was last in Napier, I visited their small aquarium there.....and they had some nice displays of the local sea life.

Why would it be restricted diodon holocanthus is permitted as are most puffers I can not see why diodon nicthermus would be restricted just a matter of someone importing it for me.

Well thats how I understand the MAF list, is there something I am missing

Currently that's how it works. Who knows after the latest review. They had suggested that all imports (and the allowed list) be specified down to the species level, rather than just genus as it is now - that could be a problem, as there is no import history of these temperate fish.

Like Tim said, there are probably better ways of getting this livestock than importing it from Tasmania.

im currently setting up a cold water marine. seems to be going fine so far.

I have decided not to use a skimmer as i fear it will skim all the good stuff out of the water as well as the crap. I have a bunch of oysters that seem to be doing well and i dont want them to starve. I also have a lot of small barnacles that look really cool with their feathers out catching any plankton that drifts by or whatever it is they eat.

crabs apparently do well, but all the crabs i have in mine stay constantly hidden under the rocks. and you will probably have problems with them fighting over teritory when they are initially put in.

the temperature of the tank is hovering around 19 degrees celcius which is pretty much the average inner harbour water temp up here in auckland. although it will definately get too hot in summer and i will need to buy a chiller.

So far a couple of Neptune's necklace seaweed specimens are doing ok and i have very little by the way of lighting. Just a single 4foot flouro tube.

so can this not be done without a chiller? i was hoping to avoid the big $$$'s

Say if i collect my live stock in Kaitaia (the far far north) and keep it in a non chilled tank in wellington? Would that do ok?

I did it with my seahorse tank over two summers and i seriously regret not getting a chiller sooner. My freezer was full of bottles of frozen water and i had two fans blowing accross the top of the tank. In desperation i would let the water out of the bottles occasionally. I would replace the bottles up to three times a day and there would be days during the summer i would sit at work thinking that if the heat goes up anymore my tank may fry.

It can be done, but it is a huge amount of work and dedication. Fans will only drop the temp about 1 - 2 degrees and the only choice you really have some times is to freeze salt water and put that in your tank.

Most DIY projects to chill the water will only end up costing more money than you want them too (IMO). You could set up the tank now and start saving for a chiller now.

Also you may have a few troubles transporting the livestock from kaitaia to Wellington, it is a long way to travel. The best thing you could do is invest in a battery air pump.
