I was wondering would a 280 gallon tank be easier to care for if it were fresh or salt water?? Or does the fish your keeping make all the difference. I realize the large volume of water will stay clean longer because there's more to 'dirty up' if you have smaller fish in comparison to the tank size. Wasn't planning on having anything nearly as large as a pacu or arowana or anything like that just because I know a larger tank would still be better and would result in frequent water changes too. So, what does anybody think from your fish keeping experience?? Thanks!!
