Sorry those measurements are wrong it's:
24x12x16 (inches) sorry guys.
a beta wouldn't work because aren't they good jumpers? Too bad, they are such pretty fish!! I tested my tank for water-proofness (lol

) and it was good so far... even if I managed to give my basement a mini-flood

oh well, its all cleaned up now!! So I just added a bunch of salt into the tank to make sure its good and clean... Is salt good enough? Do I need to add some other stuff? Oh BTW here's my plan for my tank:
6 harlequin rasboras (they grow 1.5 inch, that's approx 8 inch)
7 neon tetras (1 inch each, thats a seven-inch total)
so I have five gallons/five inches of fish left.
