ok i finally convinced my sister to get a decent tank for her betta rather than a 1.5 liter bowl :)
i found this 5 gallon tank at the lfs. Its 15" long by 5" wide or so and about a foot tall is this good dimentions for a betta. its quite long and tall for a 5gallon
but my real question is about the filter- it had an intake tube going into the filter, and the filtration itself is those Bio/Balls in front, and poly fiber pads (or white sponge stuff) with carbon media in the middle of the pads, then back into the tank. Is that good filtration?? i havent had much experience with filters.
thanks in advance for the info.
