ok... well ideally i would like to get a tank that will fit in an alcove in my wall the alcove is about 66" wide ... it looks like a great place for a tank. i also love to grow live plants in my tank so if I can find a fish that doesn't eat or dig up live plants that would be a huge bonus.
ps. If there are no guppy-eating fish that would fit in a tank this size then i will probably just move my guppies to a larger tank and take the extra ones back to the fish store. i don't want any new fish to feel cramped..
