anybody ever tryied to make a home-made fish tank?

It's only really worth it for biiiiig tanks, like hundreds of gallons and up. And even for that, it is apparently not at all easy to get the things to reliably hold water (neither losing it gradually nor catastrophically)... one of my grad students some years ago had a coupla great big huge tanks (plywood with a clear insert for viewing) for some overly big aquarium fish, he was a *big* 'fish head' type person, but although he was a high-energy type-AA-personality fix-or-build-anything handyman type, and quite skilled at it, to judge from his stories it was a big ol' headache for him and I got the impression he wouldn't do it again.

The thing you have to remember is that water exerts tremendous force pressing outwards on the glass (or whatever). And will squoodge out thru even the tiniest hint of a crack.

Even just *fixing* commercial aquaria is not all that easy, oftentimes.

Of course you can "make" small aquaria by adapting existing containers, like rubbermaid totes or big glass jars or such, and in that case, as long as the container is strong enough to hold the water's weight/force, it is no problem at all.

Good luck, have fun,

Pat
