Re: ILL NEVER SURRENDER TO THE LIKES OF YE!
Then I will find a way to keep them in captivity!
Octomush, I really do like your attitude!!!
OK, there are some exciting things about to happen over the next week, and I'm going to be a little busy, but what I'll do is post a few notes here to get you started on a very cheap, very basic (but successful) squid holding device/tank.
Ask dad for one of his biggest plastic barrels, about 400 litres [or a CLEAN 200 gallon drum] (without a lid) - the ones he probably keeps his rope in (make sure you ask him first!) - and some hose or piece of PVC pipe [we won't worry about PVC for the sake of this experiment], about 1 metre of it, about 7cm in internal diameter (this will be your airlift). You'll need an airpump, ~ 1.5 metres of air tubing, and an airstone.
You're going to keep this tank outside to begin with, so you'll need an area where the rain cannot get into the tank. You want to keep the tank in an area that gets natural light (so a dark, locked-up garage without light is no good), but not full sunlight (find some shade somewhere).
Fill the barrel with water [you cannot do this in a square or rectangular tank - it must be a barrel or cylinder]. Mark the top of the water level. Cut the piece of PVC pipe to the water level (lower it into the tank so that the pipe touches the bottom; cut it to length at the top); drill 4 small holes in the bottom of this pipe (~ 5-7mm diameter), and 4 larger holes at the very top. Cap the bottom of the pipe (or place some gauze, pantyhose or onion-bag mesh over it - just use a rubber band to hold it in place). Place the airstone on the end of the air hose and lower it [inside the pipe] to the bottom of the pipe (or hose; whatever you have handy). Turn the pump on. Water will be drawn from the bottom of the airlift, oxygenated with the airstone, raised to the top of the airlift and will be released, all oxygenated through the holes in the top of the pipe (ask your dad to do this for you; I'm sure he'll understand what I'm talking about, and he can also cut the pipe for you, and drill the holes). You need this airlift so that you don't have all of these bubbles in your tank - these tend to get inside the squid, and they don't like that.
OK, now your tank is kind-of ready (to start with). What you'll have to do now is get a protein skimmer, and these can be expensive. Alternatively you can change 1/3rd of the water every day ... but that's a big job.
Why don't you try this basic and very inexpensive tank design first, have some live food (sprats or shrimp handy), get yourself a squid, and if you can keep it alive in this basic system for more than 3 days
then you have done EXTREMELY well, and you should then invest in a protein skimmer immediately!
All the best
