Now before you get your claws ready to pounce on me for keeping fish in a tank like this, a Betta needs about a half gallon tank, I'm currently keeping two Bettas in mine (separated of course) and this tank is 1.49 Gallons. Not only is it big enough but it has places for them to hide and has a filter. They are very well taken care of.
On to the Instructable!
Step 1: Materials
You will need the following for the tank:
1. Polycarbonate: [Mcmaster Carr]
2. Extruded Acrylic: [Ridout Plastics]
3. Acrylic Glue: [Ridout Plastics]
The amount of these items will vary on the size of your tank, but for a small one like mine you are looking at 2 sheets of Polycarbonate (1' x 2'), 2' worth of Acrylic Extrusion, and about 3 ounces of Glue. This is for a 2.40" x 6.00" x 24.00" Tank.
Tools you will need:
1. Cutting Implement: I used a bandsaw with a guide to get nice strait cuts. You could also use a dremel with the linear guide attachment. (Would have been really easy with a laser cutte... winkwink r ;) )
2. News Paper to cover your work area.
3. A drinking straw (I'll explain later)
Things you will need for your fish:
1. Well.... The fish themselves of course, I wouldn't put more than two Bettas in this size tank unless you are mean.
2. Water conditioner, Assuming you are using Tap water
3. Food, mine seem to hate dried bloodworms and prefer the pellets.... go figure.
4. Filter, there are a couple that will fit my size tank but look below for the one I purchased. It works phenomenally well for $15.
5. Fake plants (Or real if you know what to do)
6. Gravel, to hold your plants down and make the bottom look nice.
7. An Easter Island head, optional of course.
8. A mesh net for when you have to transplant the fish
So far my tank has been running for four weeks going strong, I run the filter during lunch for an hour a day and it keeps the water sparkling clean. Just add some of the water treatment of your choice each week to replenish the minerals in the water.
On to construction!!
