Thanks Mr2 I think their cute. Do reg rams have a longer lifespan? How much longer?
I've never kept balloons but I'd bet that regular rams would live longer given the same conditions just like how mutts usually outlive those freaky looking purebred dogs and have a lot less health issues along the way. You can definitely add more rams in general and you won't have problems, your tank is big enough and as long as you have lots of plants they will find their own territories.
